Description

  The present invention provides a radiographic imaging system that irradiates a subject with radiation from a radiation source, detects the radiation transmitted through the subject with a radiation detector, and converts it into a radiographic image, and the radiographic image and the radiographic image. The present invention relates to an image display method for displaying related shooting menus.

  2. Description of the Related Art In the medical field, radiation image capturing apparatuses that irradiate a subject with radiation and guide the radiation transmitted through the subject to a radiation conversion panel (radiation detector) to capture a radiation image are widely used. As the radiation conversion panel, a conventional radiation film in which the radiation image is exposed and recorded, or radiation energy as the radiation image is accumulated in a phosphor and irradiated with excitation light, thereby stimulating the radiation image. A storage phosphor panel that can be extracted as light is known. These radiation conversion panels supply the radiation film on which the radiation image is recorded to the developing device to perform development processing, or supply the storage phosphor panel to the reading device to perform reading processing, A visible image can be obtained.

  On the other hand, in an operating room or the like, it is necessary to be able to immediately read out and display a radiation image from a radiation detector after imaging in order to perform a quick and accurate treatment on a patient. As a radiation detector capable of meeting such demands, a direct conversion type radiation detector using a solid state detection element that directly converts radiation into an electrical signal, or a scintillator that temporarily converts radiation into visible light, and the visible light. An indirect conversion type radiation detector using a solid state detection element that converts light into an electric signal has been developed.

  In addition, the radiation detector mentioned above is accommodated in the radiation detection cassette (cassette main-body part) which can permeate | transmit a radiation.

  Thus, as disclosed in Patent Document 1, the conventional radiographic imaging device is developed on the premise of imaging of a patient in a hospital.

  On the other hand, there is a potential demand for imaging outside a hospital, and for example, an in-vehicle radiographic imaging device for the purpose of health check using a checkup car has been proposed (Patent Document 2). However, such a radiographic imaging device has a relatively large size that can be mounted on the examination car. Therefore, for example, even if it is attempted to take a picture of a subject at a disaster site such as a natural disaster or home nursing, in the case of a disaster site, the examination vehicle cannot be moved to the disaster site. In the case of home nursing, the examination car can be moved to the home of the subject (home person) serving as the home nursing site, but the home person can be brought into the examination car at the time of photographing. Since it is necessary to guide, the burden on the home-stayer involved in the shooting is increased. Therefore, an ultra-compact and portable radiographic imaging device is required at the disaster site and the home nursing site.

  Therefore, in recent years, as disclosed in Patent Document 3, a portable radiographic imaging apparatus that can accommodate the entire system in a compact manner has been developed.

JP 2003-093354 A JP 2008-206740 A Japanese Patent Laid-Open No. 11-104117

  When the radiographic imaging device is reduced in size and weight as a whole, the radiographic imaging device can be easily moved. In this case, the radiographic imaging device is transported to a disaster site or home nursing site, and the subject is imaged after the radiographic imaging device is assembled at the site of the transport destination.

  By the way, in Japan, a person who can perform radiation irradiation (photographing of a radiographic image on a subject) on a human body as a business is a doctor and a dentist (hereinafter also simply referred to as a doctor) and a medical radiographer (hereinafter referred to as a doctor). It is defined by the Medical Radiologist Law that it is limited to simply “radiologist”. Therefore, if for some reason the doctor or the radiation technician who has the authority to irradiate radiation on the subject cannot go to the disaster site or home nursing site, someone other than the doctor or the radiation technician, Even if a person who does not have the qualification of medical radiographer defined by the Medical Radiologist (hereinafter also referred to as an operator) brings a radiographic imaging device to the site, the subject is photographed on the cassette body containing the radiation detector. Although it is possible to prepare for imaging such as position alignment, it is not possible to perform imaging on the subject. Therefore, at present, in order to carry out imaging at a disaster site or home nursing site, it is necessary for the doctor or the radiological qualification holder to accompany the site.

  In order to eliminate such inconvenience, the techniques of Patent Documents 1 and 2 are applied, and in accordance with instructions from a doctor or radiographer waiting in a waiting place (for example, a medical institution or a checkup car) where the subject cannot be directly viewed. It is assumed that photographing of a subject is performed.

  However, the technique of Patent Document 1 transmits an affected part image (radiation image) of an emergency patient (subject) carried to a medical institution to a portable terminal of a doctor who is absent from the medical institution. The doctor asks for instructions about the next imaging. Therefore, when the technique of Patent Document 1 is applied as it is, the affected area image transmitted from the site to the portable terminal in order to ask for an instruction for the next imaging is a radiographic image captured without obtaining approval from the doctor. There is a risk. Moreover, since it is necessary to transmit the affected part image to the portable terminal and ask for the next photographing instruction, the doctor cannot instruct photographing in real time to the site.

  On the other hand, the technique of Patent Document 2 is to stop radiation exposure based on an optical image obtained by photographing body motion of a subject. For this reason, even if the technique of Patent Document 2 is applied as it is, it is not possible to instruct imaging from the doctor to the site in real time.

  Further, in order to appropriately instruct the subject to take a picture of the subject while the doctor or radiologist is waiting at the waiting place, for example, the situation of the place is photographed with a camera and the optical image (still image or It is desirable that the doctor or the radiographer can instruct in real time while viewing the optical image displayed on the screen of the display device. In this case, information that the doctor or the radiographer wants to see is displayed (as large as possible) on the screen according to the radiographic image capturing situation (before and after radiographic image capturing) on the subject. Is also desirable. However, the above-mentioned documents do not propose any image display method for supporting an instruction for radiographic image capturing.

  The present invention has been made in order to solve the above-described problems, and radiation capable of performing imaging on a subject without a doctor or a radiographer going directly to a disaster site or home nursing site. An object is to provide an image capturing system and an image display method.

  Further, according to the present invention, when a doctor or a radiographer gives an instruction to the site while viewing the optical image of the site displayed on the screen, the doctor or the radiation It is an object of the present invention to provide a radiographic imaging system and an image display method capable of displaying as much information as possible on the screen as desired by an engineer.

In order to achieve the above object, a radiographic imaging system according to the present invention includes:

  On the other hand, the operator can grasp what kind of radiographic image is captured on the subject by looking at the imaging menu displayed on the mobile terminal side display unit, and the imaging menu It is possible to perform an appropriate operation (for example, positioning of a subject) according to the situation. Moreover, if the said site side optical image is also displayed on the said portable terminal side display part, the said operator can confirm the condition of the said site easily.

  Further, after the radiographic image is captured, the site-side optical image and the radiographic image are transmitted from the site-side communication unit to the standby location-side communication unit, and the console-side display unit and the portable terminal-side display unit are At least one of the imaging menu, the site-side optical image, and the radiation image is displayed.

  Accordingly, whether or not the doctor or the radiologist has obtained an appropriate radiographic image (an image suitable for interpretation diagnosis by the physician) according to the imaging menu while viewing the radiographic image displayed on the console-side display unit. Can be determined. Further, the operator can also know whether or not the radiographic image has been properly captured by viewing the radiographic image displayed on the mobile terminal side display unit.

  Thus, according to the present invention, when the doctor or the radiologist is standing by at the waiting place where the subject cannot be directly viewed, the doctor or the radiologist waits for the console side display unit. While viewing the display content, it is possible to instruct the operator in the field to take the radiation image in real time. Therefore, it is possible to perform photographing on the subject even if the doctor or the radiologist does not go directly to the site.

  In addition, as described above, since signals such as the imaging menu, the site side optical image, and the radiation image are transmitted and received between the site side communication unit and the standby location side communication unit, the console side The display unit can display as much information as possible on the screen as much as possible the doctor or the radiographer according to the radiographic image capturing state, and the mobile terminal side display unit can display the radiation.

In addition, the portable information terminal 34 can transmit and receive signals by wireless communication with a medical institution 40 (standby place) to which a doctor (or a radiographer) 38 belongs via a network 36 using a public line or the like. It is.

  The operator 32 is a person who does not have the qualifications of a medical radiographer defined by the Japanese Medical Radiologists Act. Specifically, the operator 32 is a doctor or dentist who is authorized to irradiate the subject 18 with radiation 12 (hereinafter referred to as the operator 32). , Simply a doctor) and a person other than a medical radiographer (hereinafter simply referred to as a radiographer). In the present embodiment, the subject 18 is at a disaster site or home nursing site, while the doctor (or radiologist) 38 cannot see the subject 18 directly (at a remote site) at a medical institution 40. However, the operator 32 goes to the disaster site or the home nursing site instead of the doctor 38 because he or she cannot go directly to the disaster site or the home nursing site for some reason.

  Therefore, in the present embodiment, a case will be described in which the radiation image capturing apparatus 10 is brought to such a site and the subject 12 is irradiated with the radiation 12 (radiation image capturing). In addition, since the waiting place of the doctor 38 is a place where the subject 18 cannot be seen directly, the place where the doctor 38 cannot see the subject 18 directly in the medical institution 40 is not limited to a disaster site or a home nursing site. Is also included in the field. In the following description, reference numeral 38 will be described as a physician.

  Here, the portable information terminal 34 incorporates a web camera 30 (mobile terminal side camera, site side camera) that captures a predetermined imaging region 28, while the radiation source body 16 also has a predetermined imaging region 332. A web camera 330 (a source-side camera and a field-side camera) for photographing is incorporated. That is, the web camera 30 is configured integrally with the portable information terminal 34, and the web camera 330 is also configured integrally with the radiation source main body 16 including the radiation source 14.

  In this case, the web camera 30 continuously captures the imaging region 28 and outputs a camera image (moving image) that is an optical image continuously captured. In addition, the web camera 30 captures the shooting area 28 at a predetermined time interval (intermittently), and outputs a camera image (still image) that is an optical image intermittently captured or is captured at a predetermined time. It is also possible to output a camera image (still image). On the other hand, similarly to the web camera 30, the web camera 330 continuously photographs the photographing region 332 and outputs continuously photographed camera images (moving images). Further, the web camera 330 shoots the shooting region 332 at a predetermined time interval (intermittently) and outputs a camera image (still image) shot intermittently, or a camera image (still image) shot at a predetermined time. Image) can also be output.

  The integrated configuration of the web camera 30 and the portable information terminal 34 is not limited to the configuration of FIGS. 1, 2, and 4 to 6 in which the web camera 30 is built in the portable information terminal 34. A configuration in which the web camera 30 and the portable information terminal 34 are integrally connected (connected) when the radiographic imaging device 10 is used is also included.

And (3) the radiation source body 16 and the web camera 330 are coupled when in use, and the web from the radiation source body 16 during maintenance and when not in use. A configuration in which the camera 330 can be separated (separated) is also included in an integrated configuration of the web camera 330 and the radiation source main body 16.

  Even in this case, in order to enable the web camera 330 to be separated from the radiation source main body 16 at the time of maintenance or non-use, for example, the web camera 330 may be coupled to the radiation source main body 16 by a coupling means such as a clip. . As a result, the web camera 330 is connected to the radiation source main body 16 via the connecting means only at the time of use. Further, the connecting means may be provided with a ball joint so that the orientation of the web camera 330 connected to the radiation source main body 16 can be changed. In addition, when connecting with a connection means, of course, it is necessary to connect between the web camera 330 and the radiation source main-body part 16 by wire (for example, USB cable) or wirelessly.

  Furthermore, the configuration in which the radiation source main body 16 and the web camera 330 are connected by a cable can be arranged in a state where the web camera 330 is self-supporting in a desired position as long as the length of the cable is within the range. Therefore, the degree of freedom of positioning of the web camera 330 is higher than the configuration in which the web camera 330 is built in the radiation source main body 16.

  As shown in FIGS. 1, 2, 4 to 6, and 9, the cassette body 22 has a substantially rectangular casing 42 made of a material that can transmit the radiation 12. The surface on the radiation source main body 16 side is an irradiation surface 44 to which the radiation 12 is irradiated. A guide line 46 serving as a reference for an imaging region and an imaging position is formed in an irradiation portion (irradiation field) of the radiation 12 on the irradiation surface 44. The outer frame portion of the guide line 46 (irradiation field of the radiation 12) substantially corresponds to the radiation detector 20, as shown in FIG. Also, on one side surface 48 of the housing 42, a switch 50 for starting the cassette body 22 and a USB terminal 172 to which a USB cable (not shown) is connected are arranged.

Further, the web camera 330 described above is arranged in the vicinity of the output location of the radiation 12 in the radiation source main body 16. In this case, for example, the operator 32 points the radiation source main body 16 including the web camera 330 toward the cassette main body 22 while holding the handle 310 with one hand, and the portable information terminal 34 with the other hand. Can be operated.

  In this way, by directing the radiation source body 16 toward the cassette body 22, it is possible to irradiate the radiation 12 from the radiation source 14 to the cassette body 22, and at the same time, the web camera 330 allows the cassette body to be irradiated. It is also possible to take a camera image (radiation source side optical image, site side optical image) of the unit 22.

  In this case, the web camera 330 has the subject 18 between the radiation source main body 16 and the cassette main body 22, and the imaging region of the subject 18 (the right hand of the subject 18 in FIGS. 1 and 2) and the cassette main body. A predetermined area including the range of the guide line 46 of the unit 22 is imaged as an imaging area 332. Alternatively, the web camera 330 can perform imaging so that the face of the subject 18 including the pupil enters the imaging region 332.

  The handle 310 is provided with a capacitive or resistive touch sensor 312. Therefore, when the operator 32 grips the handle 310, the hand of the operator 32 comes into contact with an electrode (not shown) constituting the touch sensor 312, and the touch sensor 312 outputs a detection signal based on the contact between the hand and the electrode. Can be output.

  Further, the radiation source main body 16 houses an irradiation field lamp 56 that projects the irradiation light 54 in addition to the radiation source 14 and the web camera 330. The irradiation field lamp 56 displays the irradiation field of the radiation 12 on the irradiation surface 44 by projecting the irradiation light 54 onto the irradiation surface 44 before the radiation 12 is output from the radiation source 14. Furthermore, a USB terminal 132 to which a USB cable (not shown) is connected is disposed on the side surface of the housing 130.

When the distance to the device 20 (distance between radiographs) is set to the distance between the source image images (SID), the irradiation field of the radiation 12 displayed on the irradiation surface 44 by the projection of the irradiation light 54 And the outer frame of the guide line 46 substantially coincide. Furthermore, it is desirable that the portion of the housing 130 through which the irradiation light 54 passes is made of, for example, a material that can transmit the irradiation light 54.

And are provided.

  The web camera 30 described above is disposed on the upper surface side of the lid 66. In the web camera 30, when the lid 66 is rotated with respect to the main body 62, the power switch 76 is turned on by the operation of the operator 32, and the portable information terminal 34 is activated, the imaging region 28 is displayed. Camera images (mobile terminal side optical image, site side optical image) are taken. Specifically, the web camera 30 performs imaging so that the face of the subject 18 including the pupil enters the imaging region 28, or the subject 18 is between the radiation source main body 16 and the cassette main body 22. Thus, imaging is performed using a predetermined area including the radiation source main body 16, the subject 18 (imaging site) and the cassette body 22 (range of the guide line 46 thereof) as the imaging area 28.

  In the present embodiment, the notebook type portable information terminal 34 is described. However, the portable information terminal 34 may be any portable terminal having various functions such as the operation unit 60 and the display unit 64, for example, a touch panel. Of course, a handheld personal computer (tablet PC) equipped with a display, a mobile phone with a screen display function, or a PDA (personal information terminal) may be used.

And a microphone 122 capable of inputting the voice of the doctor 38.

  As described above, signals are transmitted / received between the portable information terminal 34 and the communication unit 104 by wireless communication via the network 36, and the portable information terminal 34, the radiation source main unit 16, and the cassette main unit. Signals can also be transmitted to and received from the terminal 22 by wireless communication. Therefore, the portable information terminal 34 has a camera image from the web cameras 30 and 330, a radiation image from the cassette body 22 (the radiation detector 20), and the voice of the operator 32 or the subject 18 input to the microphone 80. It is possible to transmit an audio signal corresponding to the signal to the antenna 102 and the communication unit 104 of the medical institution 40 via the network 36.

  On the other hand, the communication unit 104 displays a camera image of the doctor 38 taken by the web camera 116 (a moving image, a still image taken intermittently, or a standby location side optical image that is a still image taken at a predetermined time), the doctor 38. The exposure control signal generated in the main body 108 based on the input of the exposure switch 120 and the voice signal corresponding to the voice of the doctor 38 input to the microphone 122 are transmitted via the antenna 102 and the network 36. It is possible to transmit to the portable information terminal 34. The communication unit 104 also transmits an imaging menu related to radiographic image capturing including order information, procedures, and imaging conditions to the portable information terminal 34 via the antenna 102 and the network 36.

  Accordingly, the display unit 64 of the portable information terminal 34 is configured such that the camera image of the imaging region 28 captured by the webcam 30, the camera image of the imaging region 332 captured by the webcam 330, the radiation image from the radiation detector 20, and / or The camera image of the doctor 38 taken by the web camera 116 can be displayed.

Furthermore, the speaker 78 can also output a voice corresponding to the voice of the doctor 38 or an exposure control signal (a warning sound that tells the start of the output of the radiation 12 from the radiation source 14).

  In addition, the portable information terminal 34 transmits a synchronization control signal generated based on the exposure control signal to the radiation source main body 16 and the cassette main body 22, respectively, and at the same time the radiation source according to the order information, procedure, and imaging conditions of the imaging menu. 14 and the cassette body 22 are controlled so that the output of the radiation 12 from the radiation source 14 (start) and the detection of the radiation 12 by the radiation detector 20 and the conversion to the radiation image are synchronized. It is possible to take 18 radiographic images.

  On the other hand, the display unit 112 of the console 106 is similar to the display unit 64 of the portable information terminal 34.

Further, the speaker 118 can output the sound of the operator 32 or the subject 18 and the sound corresponding to the exposure control signal.

  Here, the order information of the radiographing menu is information created by the doctor 38 using RIS, and is information for requesting radiographic imaging of the subject 18. Specifically, the order information is a radiographic image capturing method (for example, simple imaging, hand imaging) in addition to subject information for specifying the subject 18 such as the name, age, and sex of the subject 18 (patient). Is included. The technique is information indicating the imaging region of the subject 18 and the irradiation direction of the radiation 12 on the imaging region. Further, the imaging conditions are conditions for determining the radiation dose when the subject 18 is irradiated with the radiation 12 such as the tube voltage and tube current of the radiation source 14 and the irradiation time of the radiation 12.

  The doctor 38 operates the console 106 while viewing the camera images (optical images of the subject 18) of the web cameras 30 and 330 displayed on the display unit 112, so that the contents of the shooting menu including the current order information are displayed. Can be rewritten (set or changed) to an appropriate content corresponding to the subject 18 reflected in the camera image. In this case, when the rewritten imaging menu is transmitted to the portable information terminal 34, the portable information terminal 34 controls the radiation source main body 16 and the cassette main body 22 based on the rewritten imaging menu. However, it is possible to take a radiographic image of the subject 18.

  Next, the internal configurations of the radiation source main body 16 and the cassette main body 22 will be described more specifically with reference to FIGS.

  As shown in FIG. 8, the radiation source body 16 can be charged from the radiation source 14, the irradiation field lamp 56, the web camera 330, the USB terminal 132, and the USB terminal 132 from the outside. In addition, a battery 134 that supplies power to each part in the radiation source main body 16, a communication unit 136 (site side communication unit), a radiation source control unit 138 that controls the radiation source 14, and a material that transmits the radiation 12. And a collimator 146 made of a material that does not transmit the radiation 12 and transmits the irradiation light 54.

  The radiation source 14 is a field emission type radiation source.

  That is, in the radiation source 14, a disk-shaped rotating anode 152 is attached to a rotating shaft 150 that is rotated by a rotating mechanism 148, and an annular target whose main component is a metal element such as Mo is formed on the surface of the rotating anode 152. Layer 154 is formed. On the other hand, a cathode 156 is disposed facing the rotary anode 152, and an electron source 158 is disposed on the cathode 156 so as to face the target layer 154.

  The radiation source control unit 138 includes a synchronization control signal based on the exposure control signal received from the portable information terminal 34 (see FIGS. 1, 2, and 4 to 7) via the communication unit 136 by wireless communication, The radiation source 14 is controlled so as to output a predetermined dose of radiation 12 according to the imaging conditions in the imaging menu.

  That is, in the field emission type radiation source 14, the rotating anode 152 rotates by the rotation mechanism 148 rotating the rotating shaft 150 according to the control from the radiation source control unit 138, and the power supply unit 142 supplies power from the battery 134. When the voltage (negative voltage) is applied to the electron source 158 based on the power and the power supply unit 140 applies a voltage between the rotating anode 152 and the cathode 156 based on the power supply from the battery 134 (to the rotating anode 152) When a positive voltage is applied and a negative voltage is applied to the cathode 156), electrons are emitted from the electron source 158, and the emitted electrons are accelerated by the voltage applied between the rotating anode 152 and the cathode 156 to be targeted. Collides with layer 154. Radiation 12 corresponding to the collided electrons is output from the electron collision surface (focal point 160) in the target layer 154. The radiation 12 passes through the mirror 144 and is output to the outside from the radiation source main body 16 in a state where the irradiation range is narrowed by the collimator 146.

  Further, the radiation source control unit 138 controls the irradiation field lamp 56 so as to output the irradiation light 54 until the synchronization control signal is supplied from the portable information terminal 34. Thereby, the irradiation light 54 output from the irradiation field lamp 56 is reflected by the mirror 144 toward the collimator 146 and output to the outside.

  A touch sensor 312 is built in the handle 310. As described above, after the operator 32 holds the handle 310, the radiation 12 is emitted from the radiation source 14 toward the subject 18 and the cassette body 22, so that the radiation source control unit 138 is detected by the touch sensor 312. When the signal is output, power supply from the battery 134 to each part of the radiation source main body 16 may be started to start the radiation source main body 16.

  Inside the cassette body 22, as shown in FIGS. 4 to 6 and 9, a grid 162 for removing scattered rays of the radiation 12 by the subject 18 when the subject 12 is irradiated with the radiation 12 from the radiation source 14. The radiation detector 20 and the lead plate 164 that absorbs the back scattered radiation of the radiation 12 are disposed in order with respect to the irradiation surface 44 on the subject 18 side. Note that the irradiation surface 44 may be configured as a grid 162.

  In this case, as the radiation detector 20, for example, the radiation 12 that has passed through the subject 18 is once converted into visible light by a scintillator, and the converted visible light is made of a substance such as amorphous silicon (a-Si). (Hereinafter also referred to as a pixel) An indirect conversion type radiation detector that converts an electric signal into an electric signal or a solid detection element made of a substance such as amorphous selenium (a-Se) directly converts the dose of the radiation 12 into an electric signal. A direct conversion type radiation detector can be employed.

  The switch 50 and the USB terminal 172 described above are disposed on the side surface 48 of the cassette body 22. Furthermore, the inside of the cassette body 22 can be charged from the outside via the USB terminal 172, and the battery 166 supplies power to each part of the cassette body 22, and radiation is generated by the power supplied from the battery 166.

  The cassette control unit 168 and the communication unit 170 are provided with a lead plate or the like on the irradiation surface 44 side of the cassette control unit 168 and the communication unit 170 in order to avoid damage due to the irradiation of the radiation 12. It is preferable. The battery 166 supplies power to the radiation detector 20, the cassette control unit 168, and the communication unit 170 in the cassette body 22.

  As described above, when the operator 32 grips the handle 310, the touch sensor 312 outputs a detection signal, and then the radiation 12 is output from the radiation source 14, so that the radiation source body 16 is wirelessly connected to the cassette body. The detection signal may be transmitted directly to the unit 22, or the detection signal may be transmitted to the cassette body 22 via the portable information terminal 34 by radio. Thereby, when the cassette control unit 168 receives the detection signal via the communication unit 170, the cassette control unit 168 can start supplying power from the battery 166 to each unit of the cassette body 22.

  As schematically shown in FIG. 10, the radiation detector 20 includes a large number of pixels 180 arranged on a substrate (not shown), a large number of gate lines 182 that supply control signals to the pixels 180, and a large number of pixels 180.

In this case, in each pixel 180 to which the bias voltage Vb is supplied from the battery 166, charges generated by converting visible light into an electrical signal (analog signal) are accumulated, and the TFT 188 is sequentially turned on for each row. The electric charge can be read out as an image signal.

  To the TFT 188 connected to each pixel 180, a gate line 182 extending in parallel with the row direction and a signal line 184 extending in parallel with the column direction are connected. Each gate line 182 is connected to the line scan driver 190, and each signal line 184 is connected to the multiplexer 192.

In this case, the line scan driver 190 includes a plurality of switches SW1 for switching the gate lines 182 and an address decoder 194 for outputting a selection signal for selecting one of the switches SW1. An address signal is supplied from the cassette control unit 168 to the address decoder 194.

  In addition, the charge held in each pixel 180 flows out to the signal line 184 via the TFTs 188 arranged in the column direction. This charge is amplified by the amplifier 196. A multiplexer 192 is connected to the amplifier 196 via a sample and hold circuit 198. The multiplexer 192 includes a plurality of switches SW2 that switches the signal line 184, and an address decoder 200 that outputs a selection signal for selecting one of the switches SW2. An address signal is supplied from the cassette control unit 168 to the address decoder 200. An A / D converter 202 is connected to the multiplexer 192, and a radiation image converted into a digital signal by the A / D converter 202 is supplied to the cassette control unit 168.

  Note that the TFT 188 functioning as a switching element may be realized in combination with another imaging element such as a CMOS (Complementary Metal-Oxide Semiconductor) image sensor. Furthermore, it can be replaced with a CCD (Charge-Coupled Device) image sensor that transfers charges while shifting them with a shift pulse corresponding to a gate signal referred to as a TFT.

Further, the control processing unit 222 receives the exposure control signal from the medical institution 40. In this case, a synchronization control signal corresponding to the exposure control signal is generated, and the generated synchronization control signal and the imaging conditions in the imaging menu are transmitted to the radiation source body 16 and the cassette body 22. A radiation image is taken while synchronizing the output of the radiation 12 from the radiation source 14 with the detection of the radiation 12 by the radiation detector 20 and the conversion to the radiation image.

  The display unit 64 can display the shooting menu received by the control processing unit 222 and the camera image of the subject 18 (of the face including the pupil) taken by the web camera 30 or the web camera 330. Therefore, the operator 32 can determine whether or not the subject 18 registered in the order information of the shooting menu matches the subject 18 reflected in the camera image.

  That is, the operator 32 operates the operation unit 60 while viewing the display content of the display unit 64 to input the content indicating the determination result (result indicating the coincidence or mismatch between the two). If the input content matches both, the control processing unit 222 displays a result (determination result) indicating that the radiographic image can be captured with the content of the imaging menu, the communication unit 218, the antenna 216, and the network 36. Via the wireless communication to the medical institution 40. In addition, if the input content does not match, the control processing unit 222 cannot capture a radiographic image with the content of the imaging menu, so the content of the imaging menu according to the subject 18 reflected in the camera image is displayed. A result (determination result) requesting rewriting is transmitted to the medical institution 40 by wireless communication via the communication unit 218, the antenna 216, and the network 36.

  The console 106 further includes a memory 228 and a control processing unit 226 that performs various control processes. In addition, the control processing unit 226 includes an authentication processing unit 344, a control signal generation unit 346, and a linking processing unit 348.

  The control processing unit 226 is configured by the CPU of the main body unit 108, and performs various types of control processing by reading and executing a program stored in the memory 228.

  Specifically, the control processing unit 226 transmits the camera image captured by the web camera 116 to the portable information terminal 34 by wireless communication via the communication unit 104, the antenna 102, and the network 36. In addition, the control processing unit 226 transmits the voice of the doctor 38 input to the microphone 122 as a voice signal to the portable information terminal 34 by wireless communication via the communication unit 104, the antenna 102, and the network 36. Further, the control processing unit 226 outputs an audio signal transmitted from the portable information terminal 34 via wireless communication from the speaker 118 as the audio of the operator 32 or the subject 18. Needless to say, the control processing unit 226 may display the camera image captured by the web camera 116 on the display unit 112.

  Further, according to the order information in the shooting menu displayed on the display unit 64 of the portable information terminal 34, the operator 32 finds the subject 18, and then the camera of the face including the pupil of the subject 18 is detected by the web camera 30 or the web camera 330. When an image (for example, a still image) is captured, the portable information terminal 34 transmits the camera image by wireless communication via the network 36, the antenna 102, and the communication unit 104. The authentication processing unit 344 performs biometric authentication on the camera image received via the network 36, the antenna 102, and the communication unit 104 using the pupil or face of the subject 18 reflected in the camera image (in the case of the pupil). The pupil authentication process is performed to determine whether or not the subject 18 having the pupil matches the subject 18 registered in the order information.

  If the two match, the authentication processing unit 344 determines that the subject 18 in the camera image is a genuine subject 18 corresponding to the shooting menu, and can capture a radiographic image by the subject 18. The authentication result shown is transmitted to the portable information terminal 34 by wireless communication. On the other hand, if they do not match, the authentication processing unit 344 determines that the operator 32 has found a subject 18 that is different from the subject 18 indicated by the shooting menu, and determines the authentic subject 18 indicated by the shooting menu. An authentication result instructing to find out is transmitted to the portable information terminal 34 by wireless communication.

  When the doctor 38 turns on the exposure switch 120, the control signal generation unit 346 generates an exposure control signal for starting output of the radiation 12 from the radiation source 14, and the generated exposure control signal is generated. The data is transmitted to the portable information terminal 34 by wireless communication via the communication unit 104, the antenna 102 and the network 36. In addition, in the camera image of the web camera 30 displayed on the display unit 112, the imaging part of the subject 18 is not reflected in the outer frame of the guide line 46, or only a part of the imaging part is reflected. In this case, if the doctor 38 irradiates the subject 18 with the radiation 12 in this state, it is determined that an appropriate radiographic image of the imaging region cannot be obtained, and the exposure switch 120 is not turned on. The instruction content for changing the position and posture of the subject 18 is instructed by voice through the microphone 122 so that the imaging region is reflected in the outer frame of the camera. Therefore, the control signal generation unit 346 does not generate an exposure control signal when the exposure switch 120 is not turned on.

  Further, the control processing unit 226 captures each camera image, radiation image, and cassette ID information of the web cameras 30 and 330 transmitted from the portable information terminal 34 via wireless communication after capturing the radiation image, and an imaging menu. Are associated (associated) and stored in the memory 228. As described above, since the web camera 116 also captures the camera image of the doctor 38, the camera image of the doctor 38 may be associated with the above information and stored in the memory 228.

  In addition, since the memory 224 is also provided in the portable information terminal 34, for example, the control processing unit 222 is caused to function as a linking processing unit, and the shooting menu, each camera image of the webcams 30 and 330, the radiation image, and After the cassette ID information is associated and stored in the memory 224, each piece of associated information may be transmitted from the portable information terminal 34 to the medical institution 40 by wireless communication. In this case, the association processing unit 348 stores the received information (associated information) in the memory 228.

  Further, the camera image of the web camera 30 to be linked is desirably, for example, an image of the face (including the pupil) of the subject 18 photographed by the web camera 30 before the radiographic image is photographed. On the other hand, as a camera image of the web camera 330 to be linked, for example, an imaging region of the subject 18 taken (positioned) with respect to the cassette body 22 captured by the web camera 330 before radiographic imaging. An image is desirable. For example, when the subject 18 is injured on the right hand and a radiographic image is taken using the right hand as a photographing part, the camera image photographed by the web camera 330 shows the degree of injury at the photographing part (right hand). It becomes an image that understands.

  The radiographic image capturing system 11 according to the present embodiment is basically configured as described above. Next, operations thereof (radial image capturing method and image display method) are shown in FIGS. This will be described with reference to the flowchart and the screen display of the display units 64 and 112 shown in FIGS.

  Here, the characteristic functions (operations) of the present embodiment will be described separately for the first to third examples.

  The first embodiment is a flowchart of FIGS. 14 to 20 and a screen display of FIGS. 23 to 92. Since the subject 18 to be imaged is specified in advance on the medical institution 40 side, This is a case where an imaging menu is set in advance and a radiographic image of the subject 18 is captured according to the setting contents. In the first embodiment, for example, when the subject 18 is specified in advance in the home nursing field, or when the doctor 38 does not go directly to the medical institution 40, but the subject 18 is specified in advance. Applicable.

  The second embodiment is the flowchart of FIG. 21 and the screen display of FIG. 93. The doctor 38 of the medical institution 40 changes the shooting menu while viewing the subject 18 shown in the camera images of the webcams 30 and 330. This is a case where a radiographic image of the subject 18 is taken based on the changed shooting menu. This second embodiment is applied, for example, when the operator 32 at the disaster site finds out the subject 18 and the doctor 38 rewrites the photographing menu according to the subject 18 and urgently takes a radiographic image. Is possible.

  The third embodiment is the flowchart of FIG. 22 and the screen displays of FIGS. 94 to 98. When the shooting menu rewritten by the second embodiment is transmitted from the medical institution 40 to the portable information terminal 34, the subject is displayed. In this case, it is determined on the site side (operator 32 side) whether or not the 18 imaging regions and the imaging region indicated by the imaging menu match, and the determination result is notified to the medical institution 40. In the third embodiment, for example, since the subject 18 is injured in the hand, photographing of the hand is necessary, but the photographing menu is for instructing photographing of a part other than the hand (such as the chest). Applicable to the case.

  In the first to third embodiments, as an example, when the imaging region of the subject 18 is the right hand and a radiographic image of the right hand is taken, that is, since the subject 18 is injured on the right hand, A case where a radiographic image is captured as an imaging region will be described. The first to third embodiments will be described with reference to FIGS. 1 to 13 as necessary.

  First, the first embodiment will be described.

  In step S1 of FIG. 14, the operator 32 follows the instruction of the doctor 38 who has authority to irradiate the subject 12 with the radiation 12 from the medical institution 40 that cannot directly view the subject 18 to the disaster site, home nursing site, Alternatively, the attache case 98 is transported to a hospital room or the like in the medical institution 40 where the doctor 38 cannot go directly.

  Next, in step S2 after arriving at the disaster site, home nursing site or hospital room, the operator 32 takes out the radiation source main body 16, the cassette main body 22, and the portable information terminal 34 from the attach case 98, and FIG. The portable information terminal 34, the radiation source main body 16 and the cassette main body 22 are arranged so as to have the positional relationship shown in FIG. 2 and FIGS.

  In the next step S <b> 3, the operator 32 rotates the lid 66 with respect to the main body 62 around the shaft 68 of the portable information terminal 34 under the action of the hinge 70, thereby 1, 2, and 4 to 6, the operating unit 60 and the display unit 64 shown in FIGS. 1, 2, and 4 to 6 can be seen from the outside, and then the power switch 76 is turned on to activate the portable information terminal 34. . As a result, the battery 220 starts supplying power to the web camera 30, the display unit 64, the microphone 80, the communication unit 218, and the control processing unit 222 due to the power switch 76 being turned on.

  When the portable information terminal 34 is activated in this way, in the next step S4, first, the control processing unit 222 uses the ID information (for example, cassette ID information) stored in the memory 224 as the communication unit 218, the antenna 216, and It transmits to the medical institution 40 by wireless communication via the network 36, and requests the medical institution 40 to confirm the establishment of communication between the medical institution 40 and the site and to authenticate the radiographic imaging apparatus 10.

  In step S5, when the control processing unit 226 of the medical institution 40 (standby place) receives the ID information via the antenna 102 and the communication unit 104, the authentication processing unit 344 performs an ID information authentication process (step S6). In this case, the authentication processing unit 344 determines whether or not the received ID information matches the ID information (for example, cassette ID information) stored in the memory 228, and the determination result and communication are established. An authentication completion notification indicating that this has been done is transmitted to the portable information terminal 34 via the communication unit 104, the antenna 102 and the network 36 (step S7). Thereafter, the control processing unit 226 acquires the order information created by the doctor 38 using the RIS from the RIS (step S8).

  On the other hand, when the control processing unit 222 of the portable information terminal 34 receives the authentication completion notification in step S9, the control processing unit 222 completes the authentication of the ID information and establishes wireless communication between the medical institution 40 and the site. It is determined that the image has been taken, and the on-site shooting by the web camera 30 is started (step S10), and the transmission of the camera image taken by the web camera 30 to the medical institution 40 is started (step S11).

  In this case, if the camera image of the web camera 30 is a moving image, the control processing unit 222 transmits the moving image to the medical institution 40 via the communication unit 218, the antenna 216, and the network 36. Further, if the camera image is a still image taken at a predetermined time interval, the control processing unit 222 notifies the medical institution 40 via the communication unit 218, the antenna 216, and the network 36 every time the still image is acquired. The still image is transmitted.

  Therefore, after steps S10 and S11, on the portable information terminal 34 side, the camera image is transmitted to the medical institution 40 by wireless communication continuously or intermittently. Therefore, the medical institution 40 receives the camera image of the web camera 30 continuously or intermittently through the antenna 102 and the communication unit 104 after step S12. The camera images taken continuously or intermittently are sequentially stored in the memory 224 of the portable information terminal 34 or the memory 228 of the console 106.

  The web camera 30 can also capture a camera image (still image) at a predetermined time. For example, the web camera 30 captures a still image due to the operation of the operation unit 60 by the operator 32. The control processing unit 222 may transmit the camera image taken at a predetermined time to the medical institution 40 via the communication unit 218, the antenna 216, and the network 36. Even in this case, the photographed camera images are stored in the memories 224 and 228, respectively.

  On the other hand, also in the medical institution 40, the web camera 116 starts photographing the face of the doctor 38 who operates the console 106 (step S13), and transmits the information to the portable information terminal 34 via the communication unit 104, the antenna 102, and the network 36. Transmission of the camera image is started (step S14).

  Even in this case, if the camera image of the web camera 116 is a moving image, the control processing unit 226 transmits the moving image to the portable information terminal 34 via the communication unit 104, the antenna 102, and the network 36. If the camera image is a still image taken at a predetermined time interval, the control processing unit 226 obtains the still image by using the communication unit 104, the antenna 102, and the network 36 each time the portable information terminal 34 is acquired. The still image is transmitted to.

  Therefore, after steps S13 and S14, the medical institution 40 side continuously or intermittently transmits the camera image to the portable information terminal 34 by wireless communication. Therefore, the portable information terminal 34 continuously or intermittently receives the camera image of the web camera 116 via the antenna 216 and the communication unit 218 after step S15. The camera images taken continuously or intermittently are sequentially stored in the memories 224 and 228, respectively.

  Since the web camera 116 can also take a camera image (still image) at a predetermined time, for example, the web camera 116 takes a still image due to the operation of the operation unit 114 and the mouse 336 by the doctor 38. In this case, the control processing unit 226 may transmit the camera image taken at a predetermined time to the portable information terminal 34 via the communication unit 104, the antenna 102, and the network 36. Even in this case, the photographed camera images are stored in the memories 224 and 228, respectively.

  In this manner, camera image capturing is started, and the camera image is transmitted and received between the medical institution 40 and the site by wireless communication, so that the display unit 64 and the console 106 of the portable information terminal 34 display. The unit 112 can display a camera image or the like (steps S16 and S17).

  FIG. 23 to FIG. 30 illustrate the display contents of the screen 400 of the display unit 112 (of the console 106) in step S17. All the display processing related to these display contents is performed by the control processing unit 226. Yes. FIGS. 31 to 39 illustrate the display contents of the screen 430 of the display unit 64 (of the portable information terminal 34) in step S16, and all the display processing related to these display contents is the control processing unit. 222 is doing.

  23 and 24, a window 402 is displayed on the screen 400 of the display unit 112, and a display area on the left side of the window 402 is an on-site image display for displaying an on-site camera image taken by the webcam 30. On the other hand, the display area on the right side is a shooting menu display area 406 for displaying a shooting menu.

  In this case, the shooting menu display area 406 is displayed relatively large, while the on-site image display area 404 is displayed small. That is, in steps S18 to S21 to be described later, it is necessary for the doctor 38 to set the contents of the shooting menu while monitoring the on-site situation by looking at the on-site camera image. Display processing is performed such that the shooting menu display area 406 is displayed larger than the display area 404. In the field side image display area 404, for example, a camera image of the subject 18 including a pupil and a face is displayed.

  In the shooting menu display area 406, an order information display area 408 for displaying order information and a technique display area 410 for displaying a technique are arranged. As shown in FIGS. 23 and 24, the information displayed in the shooting menu display area 406 does not fit in the size of the shooting menu display area 406. The display area is relatively long with respect to the direction. Therefore, a scroll bar for moving the shooting menu display area 406 in the vertical direction is displayed at the right end of the window 402. As a result, the doctor 38 operates the mouse 336 so that the mouse pointer (cursor indicated by the arrow “→”) displayed on the screen 400 is superimposed on the scroll bar, and then clicks the mouse 336. When the mouse 336 is moved, the control processing unit 226 performs display processing for moving the display content of the shooting menu display area 406 in the vertical direction as shown in FIGS.

  Here, in the order information display area 408, “simple X-ray imaging, right-hand imaging”, which is a part of the order information, is displayed. Therefore, in the technique display area 410, a list of techniques related to hand shooting is displayed with icons 412 to 418 corresponding to this content. In these icons 412 to 418, a picture showing a photographing part of the subject 18 and a simple explanation of a photographing method corresponding to the picture are displayed.

  The icon 412 represents that the imaging region is the left hand and that the radiation 12 is irradiated from the back side of the left hand by a picture showing the left hand and the characters “left hand side irradiation”. Moreover, in this picture, the nails of the fingertips are shown in order to facilitate the distinction between the back side of the left hand and the palm side of the left hand.

  The icon 414 represents that the imaging region is the right hand and that the radiation 12 is irradiated from the back side of the right hand by a picture showing the right hand and the characters “right side irradiation”. In addition, in this picture, in order to easily distinguish the back side of the right hand and the palm side of the right hand, the fingernail is illustrated.

  The icon 416 represents that the imaging region is the left hand and that the radiation 12 is irradiated from the palm side of the left hand by a picture showing the left hand and the characters “left hand palm side irradiation”. In addition, in this picture, the palm formed on the palm is illustrated in order to facilitate the distinction between the palm side of the left hand and the back side of the left hand.

  The icon 418 represents that the imaging region is the right hand and that the radiation 12 is irradiated from the palm side of the right hand by a picture showing the right hand and the characters “right hand palm side irradiation”. In addition, in this picture, the palm formed on the palm is illustrated in order to facilitate the distinction between the palm side of the right hand and the back side of the right hand.

  In this way, since each icon 412 to 418 displays both the picture and the character of the imaging region, the doctor 38 can view the order information displayed in the order information display area 408 while viewing the order information on the screen 400. After operating the mouse 336 so that the mouse pointer displayed on the icon 414 or the icon 418 is overlaid, the mouse 336 can be clicked to easily select a procedure according to the order information (step S18, FIG. 40).

  In addition, the shooting menu display area 406 is displayed in a large size, and each of the icons 412 to 418 in the shooting menu display area 406 displays a picture portion larger than a character portion, and each picture is an actual shooting portion. Therefore, the doctor 38 can easily specify the procedure corresponding to the order information. Furthermore, since the on-site camera image is displayed in the on-site image display area 404, the doctor 38 can easily grasp the on-site situation (for example, the state of the subject 18) before the radiographic image is captured.

  Further, in the present embodiment, as described above, since the shooting menu and the camera image are displayed in the window format as in the screen display of a general personal computer, the display of the screen 400 is shown in FIGS. Instead, the display contents shown in FIGS. 25 to 30 can be used.

  In FIG. 25, most of the area in the window 402 is assigned to the shooting menu display area 406 (order information display area 408), and a switching button 420 for displaying the camera image of the web camera 30 is displayed at the lower end of the window 402. It is displayed. Therefore, when the doctor 38 operates the mouse 336 so that the mouse pointer displayed on the screen 400 and the switching button 420 overlap, when the mouse 336 is clicked, an order information display area 408 is displayed as shown in FIG. Instead, the site-side image display area 404 is displayed larger. As a result, a switching button 422 for displaying the shooting menu is displayed at the lower end of the window 402 instead of the switching button 420.

  In FIG. 26, when the doctor 38 operates the mouse 336 so that the mouse pointer displayed on the screen 400 and the switching button 422 overlap with each other, when the mouse 336 is clicked, the control processing unit 226 displays A display process for switching from the display content to the display content of FIG. 25 is performed.

  27 and 28, another window 424 having a size substantially the same as that of the window 402 is displayed on the screen 400, and the shooting menu display area 406 (order information display area 408 thereof) is displayed on the window 402. In the window 424, a site-side image display area 404 is displayed. Here, when the doctor 38 operates the mouse 336 so that the mouse pointer displayed on the screen 400 and a desired window overlap, and then clicks the mouse 336, the control processing unit 226 causes the clicked window to be displayed. The display process for displaying in front is performed.

  29 and 30, two windows 402 and 424 are displayed on the screen 400, and the doctor 38 operates the mouse 336 so that the mouse pointer displayed on the screen 400 is overlaid on the desired window. When the mouse 336 is clicked, the clicked window is displayed in full screen (the window is displayed on the entire screen 400). For example, when the doctor 38 clicks the window 402 via the mouse 336, the control processing unit 226 displays the window 402 in a full screen and performs display processing that hides the window 424 behind the window 402 displayed in the full screen. Perform (see FIG. 30). When the doctor 38 operates the mouse 336 and clicks the window 402 once again, the control processing unit 226 returns the display content of the screen 400 to the display content of FIG.

  On the other hand, as shown in FIG. 31, a window 432 is displayed on the screen 430 of the display unit 64 of the portable information terminal 34, and the display area on the upper left side of the window 432 is a shooting that displays a shooting menu. The display area on the lower left side is a menu display area 434, the display area on the lower left side is a standby area side image display area 436 for displaying the camera image of the doctor 38 taken by the web camera 116, and the right side display area is taken by the web camera 30. An on-site image display area 438 for displaying the on-site camera image is displayed.

  In FIG. 31, the field-side image display area 438 is displayed relatively large, while the shooting menu display area 434 and the standby place-side image display area 436 are displayed small. In this case, since the operator 32 needs to grasp the situation of the scene by viewing the camera image of the scene, as will be described later, the control processing unit 222 has the field-side image display area rather than the shooting menu display area 434. Display processing is performed such that 438 is displayed large.

  In addition, since the imaging menu is not transmitted from the medical institution 40 to the portable information terminal 34, the imaging menu display area 434 indicates that the imaging menu is not set (not received). "Not available" is displayed. Thereby, the operator 32 in the field can easily grasp that the shooting menu is not set because the portable information terminal 34 has not received the shooting menu.

  In the site-side image display area 438, the same camera image as the above-described site-side image display area 404 (see FIGS. 23 and 24) is displayed. Moreover, as described above, in the window 432, the site-side image display area 438 is displayed in a large size. Therefore, the operator 32 can easily grasp the situation at the site before taking the radiation image. Furthermore, since the camera image of the doctor 38 is displayed in the standby place side image display area 436, the operator 32 can recognize that the doctor 38 of the medical institution 40 has responded, and in the field. You can work with peace of mind.

  In addition, since the shooting menu and the camera image are displayed in the window format on the screen 430, the display on the screen 430 can be changed to the display contents of FIGS. 32 to 39 instead of FIG.

  In FIG. 32, most of the area in the window 432 is assigned to the field-side image display area 438, and a switching button 440 for displaying a shooting menu and a camera image of the web camera 116 are displayed at the lower end of the window 432. A switch button 442 is displayed. Here, when the operator 32 operates the operation unit 60 so that the mouse pointer displayed on the screen 430 is overlaid on the switching button 442, and then selects the switching button 442, as shown in FIG. Instead of the side image display area 438, the standby place side image display area 436 is displayed large. As a result, at the lower end of the window 432, a switching button 444 for displaying a camera image in the field is displayed instead of the switching button 442.

  Further, when the operator 32 operates the operation unit 60 so that the mouse pointer displayed on the screen 430 is overlaid on the switching button 440, and then selects the switching button 440, as shown in FIG. Instead of the side image display area 436 or the site side image display area 438, the shooting menu display area 434 is displayed in a large size. As a result, switching buttons 442 and 444 are displayed at the lower end of the window 432.

  That is, similarly to the control processing unit 226, the control processing unit 222 changes the display content of the screen 430 of the display unit 64 according to the operation content of the operation unit 60 by the operator 32 to any one of the display content of FIGS. It is possible to switch to.

  In FIGS. 35 to 37, other windows 446 and 448 having substantially the same size as the window 432 are displayed on the screen 430, the field-side image display area 438 is displayed in the window 432, and the waiting place side is displayed in the window 446. An image display area 436 is displayed, and a shooting menu display area 434 is displayed in the window 448. Here, when the operator 32 operates the operation unit 60 so that the mouse pointer displayed on the screen 430 is overlaid on a desired window, and then selects the window, the control processing unit 222 causes the selected window to be selected. The display process for displaying in front is performed.

  38 and 39, three windows 432, 446, and 448 are displayed on the screen 430, and the operator 32 operates the operation unit 60 so that the mouse pointer displayed on the screen 430 is overlaid on the desired window. Next, when the window is selected, the selected window is displayed in full screen (the window is displayed on the entire screen 430). For example, when the operator 32 clicks the window 432, the control processing unit 222 performs display processing to display the window 432 in full screen and to hide the windows 446 and 448 behind the window 432 displayed in full screen ( (See FIG. 39). When the operator 32 operates the operation unit 60 to select the window 432 once again, the control processing unit 222 returns the display content of the screen 430 to the display content of FIG.

  Returning to FIG. 15, when the doctor 38 selects a procedure according to the order information in step S <b> 18, the control processing unit 226 switches the display content of the screen 400 of the display unit 112 to the display content of FIGS. 40 and 41.

  40 and 41, the shooting menu display area 406 includes an icon 450 indicating order information, a technique display area 410 in which a picture and characters of the selected icon 412 (see FIG. 24) are displayed, and a selected icon. A shooting condition display area 452 for displaying shooting conditions according to 412 (procedure) is displayed. Since the procedure display area 410 is a comparatively large display area, the procedure display area 410 is displayed with an explanation of “irradiate radiation from the right back side” more detailed than the explanation in the icon 412. ing.

  Here, when the doctor 38 operates the mouse 336 so that the mouse pointer is placed on the icon 450 and then clicks the mouse 336, the order information display area 408 of FIG. 23 is displayed. In the imaging condition display area 452, a list of imaging conditions including the voltage and current of the radiation source 14 and the irradiation time of the radiation 12 corresponding to the selected procedure (picture and character of the icon 412) is displayed. 458 is displayed. In addition, since the subject 18 is specified in advance, if the thickness and SID of the imaging region (right hand) are known, the information is also displayed in the imaging condition display area 452.

  Therefore, the doctor 38 moves the mouse pointer displayed on the screen 400 to the icons 454 to 458 while viewing the procedure displayed in the procedure display area 410, the thickness of the imaging part displayed in the imaging condition display area 452, and the SID. Of these, by operating the mouse 336 so as to be superimposed on any one of the icons and then clicking the mouse 336, it is possible to easily select an imaging condition corresponding to the procedure (step S19).

  As a result, as shown in FIG. 42, the selected setting contents are displayed in a list, and below the shooting menu display area 406, whether the setting contents are OK or should be corrected is selected. The selection buttons 460 and 462 are also displayed.

  If it is determined that the setting contents are OK and the doctor 38 selects the selection button 460 (step S20: YES), the order information, the procedure, and the imaging condition shooting menu are set according to the setting contents selected by the doctor 38. The display content of the window 402 is switched to the display content of FIG. 43, and the message “Order information, technique, and shooting conditions have been set with this content” indicating that the shooting menu has been set is displayed (step S21).

  When a predetermined time elapses after this display is performed, the display content of the window 402 is switched to the display content of FIG. 44, and the shooting menu display area 406 is displayed in a small size in the left area of the window 402, while the right side The site-side image display area 404 is displayed large in the area. That is, in steps S18 to S21, the control processing unit 226 performs a display process for displaying the photographing menu display area 406 in a large size so that the doctor 38 can surely set the photographing menu. After the menu is set, display processing is performed to display the on-site image display area 404 in a large size in preparation for radiographic image capturing for the subject 18. Further, the control processing unit 226 stores the setting content of the shooting menu in the memory 228.

  In the shooting menu display area 406, an icon 450 indicating order information, an icon 464 indicating a procedure, and an icon 466 indicating shooting conditions are displayed. When the doctor 38 operates the mouse 336 and clicks a desired icon, information corresponding to the clicked icon is displayed on the imaging menu display area 406. Therefore, the doctor 38 can easily confirm the setting contents of the shooting menu.

  If it is necessary to correct the setting contents of the imaging menu in step S20, when the doctor 38 selects the selection button 462 (step S20: NO), the control processing unit 226 returns to step S18, and FIG. 23 and FIG. 24 display contents are displayed on the window 402.

  Further, regarding the selection of the shooting conditions in the shooting condition display area 452, the display contents of FIGS. 45 to 49 may be used instead of the display contents of FIGS.

  FIG. 45 shows, for example, the display of the imaging condition display area 452 when the doctor 38 sets the thickness of the imaging region and the SID while looking at the subject 18 reflected in the camera image displayed in the on-site image display area 404. It is the content, and can be applied when changing the thickness or SID of the imaging region. That is, in FIG. 45, the imaging condition display area 452 includes a text box 470 for inputting the thickness of the imaging region, a text box 472 for inputting the SID, and the input content is OK or correction. Selection buttons 474 and 476 for selecting whether or not to be displayed are displayed. In this case, when the doctor 38 operates the operation unit 114 to input the thickness of the imaging region and the SID in the text boxes 470 and 472 and clicks the selection button 474, the display content is switched to that shown in FIG. When the selection button 476 is clicked, the input contents in the text boxes 470 and 472 are deleted.

  In FIG. 46, in the imaging condition display area 452, a text box 480 for inputting the thickness of the imaging region, spin buttons 482 and 484 for increasing / decreasing values in the text box 480, and SID are input. Text boxes 486, spin buttons 488 and 490 for increasing / decreasing numerical values in the text box 486, and selection buttons 474 and 476 are displayed. In this case, when the doctor 38 operates the spin buttons 482, 484, 488, and 490 using the operation unit 114 or the mouse 336, the numerical values in the text boxes 480 and 486 can be set to desired numerical values. Further, when the selection button 474 is clicked after setting to a desired numerical value, the display content is switched to that shown in FIG. On the other hand, when the selection button 476 is clicked, the input contents of the text boxes 480 and 486 are deleted, or the values (initial values) before operation of the spin buttons 482, 484, 488 and 490 are the text boxes 480 and 486. Respectively.

  The setting method shown in FIGS. 47 to 49 may be applied to the setting of the voltage and current of the radiation source 14 and the irradiation time of the radiation 12 instead of the setting method using the icons 454 to 458 as shown in FIG. .

  47, similarly to the case of FIG. 45, a text box 500 for inputting a voltage value, a text box 502 for inputting a current value, and an irradiation time are input to the imaging condition display area 452. A text box 504 and selection buttons 506 and 508 for selecting whether the input content is OK or should be corrected are displayed. In this case, when the doctor 38 operates the operation unit 114 to input each numerical value in the text boxes 500 to 504 and then clicks the selection button 506, the display content is switched to that shown in FIG. When the selection button 508 is clicked, the input contents in the text boxes 500 to 504 are deleted.

  48, similarly to the case of FIG. 46, a text box 510 for inputting a voltage value, spin buttons 512 and 514 for increasing / decreasing a value in the text box 510, and current in the imaging condition display area 452. A text box 516 for inputting a value, spin buttons 518 and 520 for increasing and decreasing a numerical value in the text box 516, a text box 522 for inputting an irradiation time, and a numerical value in the text box 522 are increased and decreased. Spin buttons 524 and 526 for selection and selection buttons 506 and 508 are displayed. In this case, when the doctor 38 operates the spin buttons 512, 514, 518, 520, 524, and 526 using the operation unit 114 or the mouse 336, the numerical values in the text boxes 510, 516, and 522 are set to desired values. Is done. When the selection button 506 is clicked after the desired numerical value is set, the display contents shown in FIG. 42 are switched. On the other hand, when the selection button 508 is clicked, the input contents of the text boxes 510, 516, 522 are deleted, or the values (initial values) before operation of the spin buttons 512, 514, 518, 520, 524, 526 are set. They are displayed in text boxes 510, 516, and 522, respectively.

  FIG. 49 is different from FIG. 48 in that mAs value (current × irradiation time) is set instead of current and irradiation time. That is, the imaging condition display area 452 includes a text box 510 and spin buttons 512 and 514, a text box 528 for inputting a mAs value, and spin buttons 530 and 532 for increasing and decreasing a numerical value in the text box 528. , Selection buttons 506 and 508 are displayed. In this case, when the doctor 38 operates the spin buttons 512, 514, 530, and 532 using the operation unit 114 or the mouse 336, the numerical values in the text boxes 510 and 528 are set to desired numerical values. When the selection button 506 is clicked after the desired numerical value is set, the display contents shown in FIG. 42 are switched. On the other hand, when the selection button 508 is clicked, the input contents in the text boxes 510 and 528 are deleted, or the values (initial values) before operation of the spin buttons 512 514 530 and 532 are displayed in the text boxes 510 and 528. Each is displayed.

  44, after a predetermined time has elapsed since switching to the display content of FIG. 44, in step S22, the control processing unit 226 transmits the content of the shooting menu set in step S21 by wireless communication via the communication unit 104, the antenna 102, and the network 36. It transmits to the portable information terminal 34. In this case, on the screen 400 of the display unit 112, as shown in FIG. 50, the characters “Settings have been sent to the site” notifying that the shooting menu has been transmitted are displayed in the shooting menu display area 406. . This character is deleted when a predetermined time elapses, and as a result, the screen 400 returns to the display content of FIG.

  In step S23, when a shooting menu is received via the antenna 216 and the communication unit 218, the control processing unit 222 of the portable information terminal 34 changes the display content of the screen 430 of the display unit 64 from the content of FIG. Switch to the contents of FIG. 51 and 52, in the window 432, the upper left area is assigned to the scene side image display area 438, the lower left area is assigned to the standby place side image display area 436, and the right area is the shooting menu display area. The shooting menu is displayed in the shooting menu display area 434.

  In this case, the control processing unit 222 displays the shooting menu display area 434 (shooting menu) in a large size, while the on-site image display area 438 (on-site camera image) and the standby place-side image display area 436 (of the medical institution 40). (Camera image) is displayed small. That is, the control processing unit 222 has the shooting menu display area more than the on-site image display area 438 and the standby place-side image display area 436 so that the operator 32 can confirm the contents of the shooting menu set on the console 106. Display processing is performed to display 434 in a large size.

  The shooting menu display area 434 includes an order information display area 540 for displaying order information, a technique display area 542 for displaying procedures, a shooting condition information display area 544 for displaying shooting conditions, and the operator 32 of the shooting menu. A confirmation button 546 for notifying that the setting content has been confirmed is displayed. In other words, in the shooting menu display area 434, display content (shooting menu) substantially the same as that of the shooting menu display area 406 is displayed.

  51 and 52, in the shooting menu display area 434, the technique display area 542 is displayed in the largest size so that the operator 32 can easily recognize the technique, the order information display area 540, and the shooting conditions. An information display area 544 and a confirmation button 546 are displayed in a small size. Therefore, the operator 32 visually recognizes the picture displayed largely in the procedure display area 542 and the characters displayed under the picture, so that the imaging part of the subject 18 is the right hand and the back side of the right hand Therefore, it can be easily understood that the radiation 12 should be irradiated.

  Then, after the operator 32 confirms the shooting menu displayed in the shooting menu display area 406 (step S24), the operation unit 60 is operated so that the mouse pointer displayed on the screen 430 overlaps the confirmation button 546, and the next If the confirmation button 546 is selected, the control processing unit 222 sends a confirmation notification indicating that the operator 32 has confirmed the shooting menu to the medical institution 40 by wireless communication via the communication unit 218, the antenna 216, and the network 36. (Step S25). Thereafter, as shown in FIG. 53, the control processing unit 222 displays the letters “confirmation notification sent to hospital” in the imaging menu display area 434 in order to notify the operator 32 that the confirmation notification has been transmitted. To display. Further, the control processing unit 222 stores the shooting menu in the memory 224.

  After a predetermined time has elapsed since the characters were displayed, the control processing unit 222 switches the display content of FIG. 53 to the display content of FIG. In this case, the shooting menu display area 434 is assigned to the upper left area of the window 432, the standby location side image display area 436 is assigned to the lower left area, and the site side image display area 438 is displayed to the right area. ing. That is, in the field, since various operations are performed on the subject 18 in steps S27 to S29 and S37 to S40 after step S25, the control processing unit 222 is configured to perform the task efficiently. Display processing is performed such that the side image display area 438 is displayed in a large size, and the shooting menu display area 434 and the standby location side image display area 436 are displayed in a small size.

  In this case, in the shooting menu display area 434, a relatively large procedure display area 542, an icon 550 indicating order information, and an icon 552 indicating shooting conditions are displayed. Therefore, the operator 32 can display information on the selected icon in the shooting menu display area 434 by selecting the icons 550 and 552.

  On the other hand, when the confirmation notification is received via the antenna 102 and the communication unit 104 in step S26, the control processing unit 226 of the console 106 switches the display content of FIG. 44 in the window 402 to the display content of FIG. In the area 406, the characters “Confirmed setting contents at the site” indicating that the confirmation notification has been received are displayed. Thereby, the doctor 38 can easily grasp that the operator 32 has confirmed the setting content of the photographing menu.

  In step S24, it is sufficient that the procedure is displayed in the shooting menu display area 434. Therefore, the display content of the window 432 may be the content of FIG. 56 instead of the content of FIG. 51 and FIG. Good. In this case, in the shooting menu display area 434, an icon 550 indicating order information, an icon 552 indicating shooting conditions, a technique display area 542, and a confirmation button 546 are displayed.

  In step S27, the operator 32 finds the subject 18 corresponding to the order information of the shooting menu from the site, and then moves the subject 18 to the front of the web camera 30 so that the subject 18 (including the pupil) is located. A camera image of the face is taken (step S28). In step S29, the control processing unit 222 transmits the camera image captured in step S28 to the medical institution 40 by wireless communication via the communication unit 218, the antenna 216, and the network 36.

  When the control processing unit 226 receives the camera image via the antenna 102 and the communication unit 104 (step S30), the authentication processing unit 344 includes the subject 18 reflected in the camera image captured by the web camera 30 and the shooting menu. Authentication processing is executed to determine whether or not the subject 18 indicated by the order information matches (step S31).

  In step S <b> 31, the authentication processing unit 344 performs a known biometric authentication process using the face image of the subject 18, more preferably a known pupil authentication process using the pupil of the subject 18.

  If the subject 18 reflected in the camera image matches the subject 18 indicated by the order information as a result of the authentication processing (step S31: YES), the authentication processing unit 344 subjects the subject 18 reflected in the camera image. When a radiographic image is captured, it is determined that an appropriate radiographic image corresponding to the radiographing menu is obtained, and the determination result (authentication result) is shown in FIG. To display. When the doctor 38 confirms the authentication result and operates the mouse 336 and clicks the confirmation button 560 (step S32), the control processing unit 226 wirelessly communicates the authentication result via the communication unit 104, the antenna 102, and the network 36. Is transmitted to the portable information terminal 34 (step S33).

  On the other hand, if the subject 18 reflected in the camera image does not match the subject 18 indicated by the order information as a result of the authentication process (step S31: NO), the authentication processing unit 344 adds the camera image to the camera image. It is determined that the captured subject 18 is a person different from the genuine subject 18 indicated in the order information, and the determination result (authentication result) is displayed in the on-site image display area 404 as shown in FIG. To do. When the doctor 38 confirms the authentication result and operates the mouse 336 and clicks the confirmation button 562 (step S34), the control processing unit 226 wirelessly communicates the authentication result via the communication unit 104, the antenna 102, and the network 36. Is transmitted to the portable information terminal 34 (step S33).

  When the control processing unit 222 receives the authentication result via the antenna 216 and the communication unit 218 (step S35), the control processing unit 222 displays the authentication result in the site-side image display area 438. As shown in FIG. 59, if the subject 18 shown in the camera image of the web camera 30 matches the subject 18 indicated by the shooting menu (is the same person) (step S36: YES), the operation is performed. After confirming this display content, the person 32 executes the operations after step S37.

  On the other hand, as shown in FIG. 60, if the subject 18 shown in the camera image of the web camera 30 is different from the subject 18 indicated by the shooting menu (not an authentic subject), the authentication result is obtained (step S36: NO). The operator 32 returns to step S27 and performs the work of finding the genuine subject 18 again.

  In step S37, when the operator 32 turns on the switch 50 of the cassette body 22, the battery 166 supplies power to the radiation detector 20, the cassette controller 168, and the communication unit 170 to activate the entire cassette body 22. Let Thereby, the cassette control unit 168 transmits an activation notification signal for notifying that the cassette body 22 has been activated to the portable information terminal 34 by radio. When the operator 32 holds the handle 310 with one hand, the touch sensor 312 outputs a detection signal.

  Based on the reception of the activation notification signal, the control processing unit 222 wirelessly transmits an imaging preparation instruction signal for instructing imaging preparation and imaging conditions of the imaging menu registered in the memory 224 to the radiation source body unit 16. And to the cassette body 22.

  The battery 134 of the radiation source main body 16 always supplies power to the communication unit 136 and the radiation source control unit 138. When the detection signal is output from the touch sensor 312 and the imaging preparation instruction signal and the imaging condition are received, the radiation source control unit 138 registers the imaging condition, while the radiation source controller 138 registers the imaging condition in the irradiation field lamp 56 and the web camera 330. The battery 134 is controlled to supply power.

  Thereby, the irradiation field lamp 56 outputs the irradiation light 54 due to the power supply from the battery 134. The irradiation light 54 is reflected by the mirror 144 toward the collimator 146 and output to the outside, and is projected onto the irradiation surface 44 of the cassette body 22 (step S38).

  Here, if the distance between images is adjusted to SID, the irradiation field of the radiation 12 displayed on the irradiation surface 44 by the projection of the irradiation light 54 and the outer frame of the guide line 46 substantially coincide. Therefore, when the position of the irradiation field of the radiation 12 (the irradiation range of the irradiation light 54) and the position of the outer frame of the guide line 46 do not match, the size of the irradiation field of the radiation 12 and the size of the outer frame of the guide line 46 If the two do not match, the operator 32 adjusts the positional relationship between the radiation source main body 16 and the cassette main body 22 so that the imaging distance matches the SID.

  The cassette control unit 168 knows that the radiographic imaging apparatus 10 has entered the imaging preparation stage by transmitting the imaging preparation instruction signal and the imaging conditions also to the cassette body 22, and the cassette ID memory 214. The shooting conditions are registered in.

  In the above description, the case where the radiation detector 20 is activated due to the switch 50 being turned on has been described. Instead, due to the reception of the imaging preparation instruction signal in the cassette control unit 168, The radiation detector 20 may be activated by supplying electric power (bias voltage Vb) from the battery 166 to the radiation detector 20. Alternatively, if the communication unit 136 of the radiation source main body unit 16 transmits the detection signal from the touch sensor 312 to the outside by radio, the cassette control unit 168 is configured so that the communication unit 170 receives the detection signal by radio. The power supply from the battery 166 to the radiation detector 20 may be started.

  On the other hand, the web camera 330 starts photographing a predetermined photographing region 332 including the outer frame of the guide line 46 of the cassette body 22, and the camera image is transmitted to the portable information terminal 34 via the communication unit 136 and the antenna 340. Sent to. The control processing unit 222 of the portable information terminal 34 transmits the received camera image to the medical institution 40 by wireless communication via the communication unit 218, the antenna 216, and the network 36, and stores the camera image in the memory 224 (Step 224). S39).

  In this case, if the camera image of the web camera 330 is a moving image, the control processing unit 222 transmits the moving image to the medical institution 40 via the communication unit 218, the antenna 216, and the network 36. Further, if the camera image is a still image taken at a predetermined time interval, the control processing unit 222 notifies the medical institution 40 via the communication unit 218, the antenna 216, and the network 36 every time the still image is acquired. The still image is transmitted.

  Therefore, after steps S38 and S39, on the portable information terminal 34 side, the camera image is transmitted to the medical institution 40 by wireless communication continuously or intermittently. Therefore, the medical institution 40 continuously or intermittently receives the camera image of the web camera 330 via the antenna 102 and the communication unit 104 after step S41.

  When the web camera 330 captures a camera image at a predetermined time, the control processing unit 222 transmits the camera image captured at the predetermined time to the medical institution 40 via the communication unit 218, the antenna 216, and the network 36. To do.

  Then, the operator 32 irradiates the cassette body 22 in step S40 after adjusting the distance between the images to SID as described above and matching the irradiation field of the radiation 12 with the outer frame of the guide wire 46. The subject 18 is arranged on the surface 44 side, and the subject 18 is positioned (positioned) so that the imaging part of the subject 18 falls within the outer frame of the guide line 46.

  In this case, the web camera 30 images the imaging region 28 including the imaging part (right hand) of the subject 18, the radiation source main body 16, and the irradiation surface 44 side of the cassette main body 22. Further, the web camera 330 captures an imaging region 332 including the imaging part (right hand) of the subject 18 and the irradiation surface 44 side of the cassette body 22. When the subject 18 is injured on the right hand and radiographing is performed using the right hand as an imaging part, the camera images taken by the web cameras 30 and 330 are images showing the degree of injury at the imaging part. It becomes.

  The display unit 64 of the portable information terminal 34 displays each camera image taken by the web cameras 30 and 330. Further, since each camera image taken by the web cameras 30 and 330 is transmitted from the portable information terminal 34 to the medical institution 40 by wireless communication via the network 36 (steps S11 and S39), the display unit 112 of the console 106 is displayed. In addition, each camera image taken by the web cameras 30 and 330 is displayed.

  61 and 63 illustrate cases where the camera images are displayed in the window 432 of the screen 430 of the display unit 64. FIGS. 62 and 64 illustrate the window 402 of the screen 400 of the display unit 112. The case where each camera image is displayed is illustrated.

  In this case, each of the site-side image display areas 404 and 438 includes a mobile terminal-side image display area 404a and 438a that displays a camera image captured by the web camera 30, and a radiation source side that displays a camera image captured by the web camera 330. It is divided into image display areas 404b and 438b, respectively.

  As described above, since each camera image taken by the web cameras 30 and 330 is transmitted from the portable information terminal 34 to the medical institution 40 via the network 36 in real time, the portable terminal side image display areas 404a and 438a include The same camera images taken by the web camera 30 are respectively displayed, and the same camera images taken by the web camera 330 are respectively displayed in the radiation source side image display areas 404b and 438b. Moreover, these camera images are displayed larger than the shooting menu display areas 406 and 434 and the standby location side image display area 436.

  Here, FIGS. 61 and 62 illustrate a state in which the imaging region (right hand) of the subject 18 is positioned within the outer frame of the guide line 46, while FIGS. The imaging | photography site | part is showing in figure the state which is not positioned in the said outer frame.

  Therefore, in step S42, the doctor 38 determines whether or not the imaging region of the subject 18 is appropriately positioned while viewing the camera images displayed in the mobile terminal side image display area 404a and the radiation source side image display area 404b. To do.

  For example, as shown in FIG. 61 and FIG. 62, when the imaging part (right hand) of the subject 18 is a camera image reflected in the outer frame of the guide line 46, the doctor 38 is currently displayed. If imaging is performed with the positional relationship between the imaging region and the guide line 46, it is determined that an appropriate radiographic image of the subject 18 can be obtained (step S42: YES), and the microphone 122 is used for voice or operation. By operating the unit 114 and the mouse 336, it is transmitted to the operator 32 at the site that the positioning is OK (the preparation for photographing has been completed) (step S43). In this case, the control processing unit 226 carries the audio input to the microphone 122 or a signal corresponding to the operation content of the operation unit 114 and the mouse 336 by wireless communication via the communication unit 104, the antenna 102, and the network 36. It transmits to the information terminal 34 (step S44).

  Based on the signal received via the antenna 216 and the communication unit 218 (step S45), the control processing unit 222 of the portable information terminal 34 indicates that the preparation for photographing has been completed as shown in FIG. 65 or 66. The display content of “Positioning OK” is displayed in the standby location side image display region 436 or the site side image display region 438. Alternatively, the completion of preparation for photographing may be notified from the speaker 78 by voice. Therefore, the operator 32 can grasp that the preparation for photographing has been completed by confirming the display content of the window 432 or by listening to the sound from the speaker 78 (step S46: YES).

  In this case, when the character “Positioning OK” is displayed on the image of the doctor 38 in the standby location side image display area 436, the operator 32 feels at ease that the doctor 38 has confirmed. Further, when the characters “Positioning OK” are displayed over the camera image in the on-site image display area 438, the operator 32 can easily understand that the radiographic image can be taken by this positioning. Can do.

  On the other hand, as shown in FIG. 64 and FIG. 64, when the image of the subject 18 (right hand) is a camera image that does not fit within the outer frame of the guide line 46, the doctor 38 It is determined that an appropriate radiographic image of the subject 18 cannot be obtained even if imaging is performed based on the positional relationship between the displayed imaging region and the guide line 46 (step S42: NO), and the microphone 122 is used for voice. Alternatively, by operating the operation unit 114, the fact that the positioning is NG (moving the imaging region within the outer frame of the guide line 46) is transmitted to the operator 32 at the site (step S47). In this case, the control processing unit 226 carries the audio input to the microphone 122 or a signal corresponding to the operation content of the operation unit 114 and the mouse 336 by wireless communication via the communication unit 104, the antenna 102, and the network 36. It transmits to the information terminal 34 (step S44).

  Based on the signal received via the antenna 216 and the communication unit 218 (step S45), the control processing unit 222 of the portable information terminal 34 indicates that the positioning is NG as shown in FIG. 67 or 68. The display content “Please move the patient's right hand to the center” is displayed in the standby location side image display region 436 or the site side image display region 438. Alternatively, the speaker 78 may notify that the positioning is NG by voice. Therefore, the operator 32 can grasp that the positioning needs to be performed again by confirming the display content of the window 432 or by listening to the sound from the speaker 78 (step S46: NO). .

  In this case, when the characters “Please move the patient's right hand to the center” are displayed over the image of the doctor 38 in the standby place side image display area 436, the operator 32 is an instruction from the doctor 38. Can be understood immediately. In addition, if the characters “Please move the patient's right hand to the center” are displayed on the camera image in the on-site image display area 438, the operator 32 cannot take a radiographic image with this positioning. It can be easily understood.

  When notifying the operator 32 of positioning OK or NG, the display content of FIG. 69 or 70 may be used instead of FIG. 65 to FIG. In FIG. 69 and FIG. 70, the standby place side image display area 436 is displayed large on the right side of the window 432, while the shooting menu display area 434 and the site side image display area 438 are displayed small on the left side. The characters “Positioning OK” or “Please move the patient's right hand to the center” are superimposed on the image of the doctor 38 displayed in the display area 436. That is, it is necessary to accurately position the subject 18 at the stage of preparation for radiographic image capturing. Therefore, the standby location side image display area 436 is displayed in a large size and the above characters are displayed in an enlarged manner, whereby the determination result of the doctor 38 can be emphasized and notified to the operator 32.

  In FIG. 61, FIG. 62, FIG. 65, FIG. 66, FIG. 69 and FIG. 71, the camera images displayed in the mobile terminal side image display areas 404a and 438a and the source side image display areas 404b and 438b include The right hand, which is the 18 imaging parts, and at least a part of the right arm are reflected. At least at the stage of imaging preparation, the doctor 38 gives instructions to the operator 32 while grasping the entire imaging region, while the operator 32 needs to perform a predetermined operation while grasping the entire imaging region. As described above, by displaying the camera image including the right hand and at least a part of the right arm, it is possible to efficiently perform the shooting preparation.

  Further, at the time of positioning the subject 18, at least the on-site camera images (camera images of the web cameras 30 and 330) need only be displayed in the window 402, so that the shooting menu and the camera image of the web camera 116 are displayed as shown in FIG. 32. You may hide and display only the on-site camera image.

  Furthermore, if the characters “Positioning OK” and “Please move the patient's right hand to the center” are standard sentences, instead of voice instructions from the doctor 38, as shown in FIG. Selection buttons 564 and 566 for selecting whether the positioning is OK or NG may be displayed on the display area 404. As a result, the doctor 38 operates the mouse 336 and simply clicks the selection button 564 or the selection button 566, so that the instruction content corresponding to the clicked selection button is transmitted from the medical institution 40 to the portable information terminal 34. The work load on the doctor 38 is reduced. Note that the contents of any of FIGS. 65 to 70 are displayed in the window 432 of the screen 430 of the display unit 64 in accordance with the contents of the instruction.

  Note that when the positioning is determined in step S42, the display content of the window 402 may be the content of FIG. 72 or FIG.

  In FIG. 72, the camera image of the web camera 30 is displayed in a large size, and a switching button 568 for displaying the camera image of the web camera 330 is displayed at the lower end of the window 402. Therefore, when the doctor 38 operates the mouse 336 and clicks the switching button 568, the camera image of the webcam 330 is displayed large as shown in FIG. 73, and the camera image of the webcam 30 is displayed at the lower end of the window 402. A switching button 570 for displaying is displayed. Therefore, in the display of FIG. 72 or 73, since the camera image at the site is displayed in an enlarged manner, the doctor 38 can more easily determine whether or not the positioning is appropriate.

  As shown in FIG. 74, an icon 572 indicating an exposure switch may be displayed below the shooting menu display area 406 in the window 402 after step S44. As described above, the console 106 includes the exposure switch 120. However, when the exposure switch 120 cannot be used, an instruction to irradiate the radiation 12 may be given using the icon 572.

  In step S48, the doctor 38 turns on the exposure switch 120 (or clicks the icon 572 indicating the exposure switch) on the assumption that the preparation for imaging is completed (step S42: YES, steps S43, S44). To do). Thereby, the control signal generation unit 346 of the control processing unit 226 generates an exposure control signal for starting the output of the radiation 12 from the radiation source 14, and is carried via the communication unit 104, the antenna 102, and the network 36. It transmits to the information terminal 34 (step S49).

  When the control processing unit 222 receives the exposure control signal via the antenna 216 and the communication unit 218 (step S50), the control processing unit 222 starts the output of the radiation 12 from the radiation source 14 and detects the radiation 12 in the radiation detector 20. And a synchronization control signal for performing radiographic imaging of the subject 18 by generating synchronization with the radiographic image conversion, and the radiation source main body 16 and the cassette main body via the communication unit 218 and the antenna 216. The synchronization control signal is transmitted to the unit 22.

  In step S <b> 51, when the radiation source control unit 138 receives the synchronization control signal via the antenna 340 and the communication unit 136, the radiation source lamp 56 stops the power supply from the battery 134 to the irradiation field lamp 56. Is stopped, and the radiation source 14 is controlled so as to irradiate the subject 18 with the radiation 12 having a predetermined dose according to the imaging conditions registered in the radiation source controller 138.

  Thus, in the radiation source 14, the rotating mechanism 148 rotates the rotating shaft 150 and the rotating anode 152 according to the control from the radiation source control unit 138, while the power source unit 142 is based on the power supply from the battery 134. Since a negative voltage is applied to the electron source 158 and the power supply unit 140 applies a voltage between the rotating anode 152 and the cathode 156 based on the power supply from the battery 134, the electrons emitted from the electron source 158 are It is accelerated by the voltage applied between the rotating anode 152 and the cathode 156 and collides with the target layer 154. From the electron collision surface (focal point 160) of the target layer 154, the radiation 12 corresponding to the collided electrons is emitted. Is output.

  The radiation 12 passes through the mirror 144, is output to the outside from the radiation source main body 16 in a state where the irradiation range is narrowed by the collimator 146, and is irradiated onto the subject 18. In this case, when the subject 12 is irradiated with the radiation 12 for a predetermined exposure time (irradiation time) based on the imaging conditions, the radiation 12 passes through the subject 18 and reaches the radiation detector 20 in the cassette body 22. It reaches.

  In step S52, when the radiation detector 20 is an indirect conversion type radiation detector, the scintillator constituting the radiation detector 20 emits visible light having an intensity corresponding to the intensity of the radiation 12, and the photoelectric conversion layer. Each pixel 180 constituting the 186 converts visible light into an electric signal and accumulates it as an electric charge. Next, charge information that is a radiographic image of the subject 18 held in each pixel 180 is read in accordance with an address signal supplied from the address signal generation unit 212 constituting the cassette control unit 168 to the line scanning drive unit 190 and the multiplexer 192. .

  That is, the address decoder 194 of the line scan driver 190 outputs a selection signal according to the address signal supplied from the address signal generator 212 to select one of the switches SW1, and the TFT 188 connected to the corresponding gate line 182. A control signal Von is supplied to the gates of the first and second gates. On the other hand, the address decoder 200 of the multiplexer 192 outputs a selection signal in accordance with the address signal supplied from the address signal generation unit 212, sequentially switches the switch SW2, and is connected to the gate line 182 selected by the line scan driving unit 190. The radiographic image as the charge information held in each pixel 180 is sequentially read out via the signal line 184.

  The radiation image read out from each pixel 180 connected to the selected gate line 182 is amplified by each amplifier 196, sampled by each sample hold circuit 198, and then A / D converter via the multiplexer 192. 202, and is converted into a digital signal. The radiographic image converted into the digital signal is temporarily stored in the image memory 210 of the cassette control unit 168 (step S53).

  Similarly, the address decoder 194 of the line scan driver 190 sequentially switches the switch SW 1 according to the address signal supplied from the address signal generator 212, and the charge held in each pixel 180 connected to each gate line 182. A radiation image as information is read out through the signal line 184 and stored in the image memory 210 of the cassette control unit 168 through the multiplexer 192 and the A / D converter 202 (step S53).

  The radiographic image stored in the image memory 210 is transmitted to the portable information terminal 34 by wireless communication via the communication unit 170 together with the cassette ID information stored in the cassette ID memory 214. The control processing unit 222 of the portable information terminal 34 stores the radiation image and cassette ID information received via the antenna 216 and the communication unit 218 in the memory 224, and also stores the radiation image and cassette ID information in the communication unit 218, the antenna 216, and the antenna 216. Transmission is performed by wireless communication via the network 36 (step S54). In addition, the control processing unit 222 displays the radiation image stored in the memory 224 on the screen 430 of the display unit 64 (Step S55).

  On the other hand, the control processing unit 226 stores the radiographic image and the cassette ID information received via the antenna 102 and the communication unit 104 in the memory 228 (step S56), and the radiographic image stored in the memory 228 is displayed on the display unit 112. It is displayed on the screen 400 (step S57).

  75 and 76 show the display content of the screen 430 of the display unit 64 in step S55, and FIG. 77 shows the display content of the screen 400 of the display unit 112 in step S57.

  In the window 432 of the screen 430 in FIG. 75, the imaging menu display area 434 is assigned to the upper left area, the standby place side image display area 436 is assigned to the lower left area, and the radiation image is displayed in the right area. A radiation image display area 580 is assigned. In addition, a switching button 574 for displaying the camera image of the web camera 30 and a switching button 576 for displaying the camera image of the web camera 330 are displayed at the lower end of the window 432.

  In addition, as shown in FIGS. 1, 61, 62, 72, and 73, radiographic images are taken with the right hand of the subject 18 lying on the irradiation surface 44 of the cassette body 22. Normally, a radiographic image oriented in the same direction as the camera image is displayed in the radiographic image display area 580. However, the control processing unit 222 captures the radiographic image so that the operator 32 can easily view the radiographic image. The image is rotated 90 ° and displayed in the radiation image display area 580 (see FIG. 75).

  In the display content of FIG. 75, since the radiographic image is displayed large, the operator 32 can easily confirm whether or not the radiographic image has been acquired. If the operator 32 operates the operation unit 60 and selects the switching buttons 574 and 576, a camera image corresponding to the selected switching button is displayed in a large size instead of the radiation image.

  In the case of FIG. 76, in the window 432 of the screen 430, the imaging menu display area 434 is assigned to the upper left area, the radiation image display area 580 is assigned to the lower left area, and the mobile terminal is assigned to the right area. The side image display area 438a and the radiation source side image display area 438b are allocated in parallel. A switching button 578 for displaying a camera image of the doctor 38 is displayed at the lower end of the window 432.

  This is because, even when radiographic images are taken, there is a possibility that a re-imaging instruction may be given from the doctor 38, as will be described later. Therefore, as shown in FIG. 76, the mobile terminal side image display region 438a and the radiation source side This is because if the image display area 438b is displayed in a large size, it is possible to respond quickly even if there is an instruction to re-shoot.

  In the window 402 of the screen 400 in FIG. 77, an imaging menu display area 406 is assigned to the left area, and a radiation image display area 582 for displaying a radiographic image is assigned to the right area. A switching button 570 for displaying the camera image of the web camera 30 and a switching button 568 for displaying the camera image of the web camera 330 are displayed at the lower end of the window 402. Furthermore, in the imaging menu display area 406, in addition to the icons 450, 464, and 466, whether or not the radiographic image displayed in the radiographic image display area 582 is an appropriate image (an image suitable for interpretation diagnosis by the doctor 38). Selection buttons 584 and 586 for determining whether or not).

  Even in this case, the control processing unit 226 rotates the captured radiographic image by 90 ° and displays the radiographic image in the radiographic image display area 582 so that the doctor 38 can easily view the radiographic image.

  75 and 77, the radiographic image of the right hand as an imaging region is displayed large in the entire radiographic image display areas 580 and 582. This is because it is necessary to accurately determine whether or not the right-hand radiographic image is an image suitable for diagnostic interpretation in step S58, which will be described later. This is because there is no need to display. Accordingly, one of the right hand and the right arm displayed in the mobile terminal side image display areas 404a and 438a and the source side image display areas 404b and 438b (see FIGS. 61, 62, 65, 66, 69 and 71). In the radiographic image display areas 580 and 582, the radiographic image of the right hand is enlarged and displayed in the entire display area as compared with the camera image including the part. That is, the right-hand radiographic images in the radiographic image display areas 580 and 582 are larger (wider) than the right-hand optical images displayed in the mobile terminal-side image display areas 404a and 438a and the source-side image display areas 404b and 438b. Is displayed.

  In step S58, when the doctor 38 determines that the radiographic image is an appropriate image (step S58: YES), the doctor 38 operates the mouse 336 and clicks the selection button 584 indicating that the imaging is OK (step S58). Step S59).

  Thereby, in step S60, the linking processing unit 348 of the control processing unit 226 causes (1) a shooting menu for the current radiographic image shooting, and (2) the authentic subject 18 used in the processing of steps S31 and S32. A camera image of the face, (3) a camera image of the positioning OK used in the processing of steps S42 and S43 (of the imaging region of the subject 18), (4) the radiation image, (5) cassette ID information, (6) a web camera The camera image of the doctor 38 photographed by 116 (the doctor in charge at the current photographing) is linked (associated) and stored in the memory 228. Each camera image to be linked may be a still image or a moving image.

  Since these pieces of information are all stored in the memory 228, the linking processing unit 348 reads out information to be linked (photographing menu, various images, cassette ID information) from the memory 228, and links them. Each piece of associated information is stored in the memory 228. Therefore, the linking processing unit 348 can easily perform the linking process.

  By associating the pieces of information in this way, the correspondence between the pieces of information becomes clear, and the doctor 38 can efficiently perform an interpretation diagnosis. The doctor 38 may input the cassette ID information or the ID information of the subject 18 by operating the operation unit 114 of the console 106, for example, when performing the interpretation diagnosis. The control processing unit 226 searches for whether or not ID information that matches the input ID information is stored in the memory 228, and when the matching ID information can be searched, each control information 226 is associated with the ID information. Information is displayed on the display unit 112. Of course, such interpretation diagnosis may be performed not only on the console 106 but also in the RIS.

  In addition, since the camera image of the face of the subject 18 is an image used in actual authentication processing (biometric authentication processing, pupil authentication processing), it is possible to reliably link the wrong information due to the difference in the subject 18. Can be prevented. Furthermore, since the camera image of the imaging region of the subject 18 and the radiographic image are linked, it is possible to compare the radiographic image with the situation of the imaging region (for example, the situation of the right hand injury).

  After completion of the above linking, the control processing unit 226 switches the display content of the window 402 to the content of FIG. 78 and inquires of the doctor 38 whether or not to continuously shoot the subject 18 (step S61). In this case, instead of the selection buttons 584 and 586, selection buttons 588 and 590 for selecting whether or not to perform continuous shooting are displayed in the shooting menu display area 406, and continuous shooting is not performed. For example, the doctor 38 operates the mouse 336 and clicks the selection button 590 indicating that continuous shooting is not performed (step S61: NO).

  Next, the control processing unit 226 switches the display content of the window 402 to the content of FIG. 79 and determines whether or not to shoot the subject 18 under different conditions (different order information, procedure or shooting conditions), or other subject The doctor 38 is inquired whether or not to perform imaging for 18 (step S62). In this case, instead of the selection buttons 588 and 590, the shooting menu display area 406 is used to select whether to shoot the subject 18 under different conditions or whether to shoot the other subject 18 or not. If the selection buttons 592 and 594 are displayed and the imaging different from the current imaging is not performed, the doctor 38 operates the mouse 336 to click the selection button 594 indicating that the different imaging is not performed. (Step S62: NO).

  Through the processing of steps S58 to S62 described above, the control processing unit 226 transmits the instruction content indicating that the current imaging is OK and the radiographic image capturing is completed in the current imaging to the communication unit 104 and the antenna 102. And it transmits to the portable information terminal 34 by radio | wireless communication via the network 36 (step S63).

  When the control processing unit 222 of the portable information terminal 34 receives the instruction content via the antenna 216 and the communication unit 218 (step S64), it is determined whether the instruction content is a shooting OK instruction content (step S65). Are determined in order (step S66) and whether the instruction is for shooting under different conditions or shooting for another subject 18 (step S67).

  The instruction content is the instruction content for photographing OK (step S65: YES), not the instruction content for continuous photographing (step S66: NO), and the instruction content for photographing under different conditions or photographing with respect to another subject 18 If NO (step S67: NO), the control processing unit 222 determines that the instruction content is the instruction content indicating that the imaging is OK and that the radiographic image has been captured in the current imaging (step S68). ), The display content of the screen 430 of the display unit 64 is switched to the display content of FIG.

  In this case, instead of the site-side image display area 438 (the mobile terminal-side image display area 438a and the radiation source-side image display area 438b), the standby place-side image display area 436 is displayed in a large size and is superimposed on the camera image of the doctor 38. The text “Shooting OK” is displayed. Thereby, the operator 32 can easily grasp that the photographing of the subject 18 has been completed.

  In the next step S <b> 69, the operator 32 stops the portable information terminal 34 by operating the operation unit 60 or pressing the power switch 76. Thereby, the power supply from the battery 220 to each part in the portable information terminal 34 is stopped, and the wireless communication between the portable information terminal 34 and the medical institution 40 is also stopped. Further, since the output of the detection signal from the touch sensor 312 is stopped when the operator 32 moves away from the handle 310, the radiation source control unit 138 supplies power from the battery 134 to each part of the radiation source main body unit 16. Stop. Thereby, the wireless communication between the radiation source main body 16 and the portable information terminal 34 and the shooting of the camera image by the web camera 330 are also stopped. Furthermore, when the operator 32 presses the switch 50, the cassette body 22 is stopped, power supply from the battery 166 to each part of the cassette body 22 is stopped, and the cassette body 22, the portable information terminal 34, Wireless communication between them will also stop.

  In the next step S70, the operator 32 rotates the lid 66 toward the main body 62 around the shaft 68 of the portable information terminal 34 under the action of the hinge 70, so that the protrusion 72 and the recess 72 are recessed. 74 is fitted, and the portable information terminal 34 is folded. Next, the operator 32 houses the radiation source main body 16, the cassette main body 22, and the portable information terminal 34 in the attach case 98. Then, the operator 32 takes the attache case 98 back to the medical institution 40 to which the operator 32 belongs (step S71).

  As shown in FIGS. 81 and 82, a radiographic image is erroneously captured in a state where the imaging region of the subject 18 is not contained within the outer frame of the guide line 46, and the radiographic image is displayed on each display unit 64, When displayed on the screens 400 and 430 of 112, the doctor 38 determines that re-imaging is necessary because an appropriate radiographic image has not been acquired (step S58: NO), and the mouse 336 is operated to perform NG. A selection button 586 indicating that there has been is clicked (step S72).

  Thereby, the control processing unit 226 transmits the re-shooting instruction content to the portable information terminal 34 by wireless communication via the communication unit 104, the antenna 102, and the network 36 (step S63). When the control processing unit 222 of the portable information terminal 34 receives the instruction content via the antenna 216 and the communication unit 218 (step S64), the control processing unit 222 determines whether the instruction content is OK for photographing (step S65). In this case, since the instruction content is the instruction content for re-photographing (imaging NG) (step S65: NO), the control processing unit 222 switches the display content of the screen 430 of the display unit 64 to the content of FIG.

  In FIG. 83, in the standby location side image display area 436, the characters “photographing NG. Re-photographing.” Instructing re-photographing are displayed together with the camera image of the doctor 38. Therefore, the operator 32 can surely recognize that re-shooting is necessary. Then, the operator 32 returns to step S40, positions the subject 18 again, and enters preparation for re-shooting.

  At that time, as shown in FIGS. 84 and 85, each screen 400, 430 includes an on-site side image display area 404, 438 (mobile terminal side image display areas 404a, 438a and radiation source side image display areas 404b, 438b). May be displayed in a large size, and a radiation image for which imaging has failed may be displayed in a small size in the radiation image display areas 580 and 582.

  In the above description, the re-imaging instruction has been described in the case where the radiographic image is mistakenly taken in a state where the imaging region of the subject 18 is not within the outer frame of the guide line 46. In the present embodiment, the description is not limited to this. For example, even when the imaging region is within the outer frame of the guide line 46 during positioning, the imaging region is the body of the subject 18 when capturing a radiographic image. The present invention can also be applied to a case where the photographing is performed in such a state that the guide line 46 is detached from the outer frame by movement. Even in this case, as shown in FIG. 82, since the radiographic image is displayed in a large size in the window 402, the doctor 38 can easily understand that the radiographic image has failed to be captured, and the re-imaging can be performed quickly. You can give instructions.

  Further, in step S61 and FIG. 78, when the doctor 38 clicks the selection button 588 indicating that continuous shooting is performed by operating the mouse 336 (step S61: YES), the medical institution 40 continues to the portable information terminal 34. Instruction contents indicating photographing are transmitted (steps S63 and S64). Therefore, the control processing unit 222 returns to step S40 or step S50 based on the instruction content indicating continuous shooting (step S66: YES) and prepares for the next shooting. The medical institution 40 also returns to step S42 or step S48 to prepare for the next photographing.

  Furthermore, in step S62 and FIG. 79, when the doctor 38 operates the mouse 336 and clicks the selection button 592 indicating that shooting is performed under different conditions or shooting with respect to another subject 18 (step S62: YES), Instruction contents indicating new photographing are transmitted from the medical institution 40 to the portable information terminal 34 (steps S63 and S64). Therefore, the control processing unit 222 returns to step S23 based on the instruction content indicating new photographing (step S67: YES) and prepares for the next photographing. The medical institution 40 also returns to step S8 or step S18 to prepare for the next photographing.

  In the first embodiment, the screen display of FIGS. 86 to 92 is not limited to the above description.

  86 and 87, the same as in the case of FIG. 32, only the radiation images are displayed in large size in the windows 402 and 432. Thus, by displaying the radiographic image in a large size, the doctor 38 can easily determine whether or not the radiographic image is an appropriate image, while the operator 32 can select what type of radiation. It is possible to easily grasp whether an image is obtained.

  A plurality of switching buttons 422, 440, 442, 568, 570, 574, and 576 are displayed at the lower ends of the windows 402 and 432, respectively. In this case, when any one switching button is selected (clicked), information (image) corresponding to the switching button is displayed in a large size instead of the radiographic image, so that the doctor 38 or the operator 32 is large. The displayed information can be easily confirmed, and unnecessary information can be prevented from being displayed.

  88 and 89 show a radiographic image and a camera image of the face of the subject 18 captured by the web camera 30 before capturing the radiographic image (portable terminal side image display areas 404c and 438c) in the area on the right side of the windows 402 and 432, respectively. ), A camera image captured by the web camera 30 before capturing the radiation image (images of the radiation source main body 16, the imaging region and the cassette main body 22 displayed in the mobile terminal side image display areas 404 a and 438 a), and radiation Illustrated when four screens of camera images taken by the web camera 330 (images taken in the radiation source side image display areas 404b and 438b and the image of the cassette body 22) before the image is taken are displayed. It is.

  As described above, the association processing unit 348 includes (1) an imaging menu, (2) a camera image of the face of the subject 18, (3) a camera image of the imaging region, (4) a radiation image, and (5) cassette ID information. (6) The camera image of the doctor 38 is linked and stored in the memory 228. In FIG. 88 and FIG. 89, each piece of information (each image) other than the cassette ID information is displayed in a lump.

  Therefore, for example, if the screen shown in FIG. 88 is displayed in step S59 before linking (step S60), the doctor 38 can grasp the information to be linked and specify the subject 18 and the imaging region. It is possible to quickly grasp the situation. In step S68, by performing the screen display of FIG. 89, the operator 32 can easily understand what information is associated. Furthermore, by displaying these pieces of information collectively on the screen at the time of interpretation diagnosis, the doctor 38 can efficiently proceed with the interpretation diagnosis work.

  90 and 91, the web camera 30 takes a close-up image of the pupil of the subject 18 in step S28, and as a result, when the on-site image display areas 404 and 438 are displayed enlarged in the windows 402 and 432, the subject is displayed. 18 shows a state in which 18 pupils are enlarged and displayed. In this way, by taking a close-up image of the pupil of the subject 18, the pupil authentication process performed by the authentication processing unit 344 in step S 31 can be performed more accurately. It is possible to reliably prevent the tying.

  FIG. 92 illustrates a case where a list of all the techniques registered in the memory 228 is displayed in the technique display area 410 with icons 630 to 638, not limited to the technique according to the order information. On these icons 630 to 638, a picture indicating the imaging region of the subject 18 and characters indicating the imaging region are displayed. The icon 630 indicates that the imaging region is a hand, the icon 632 indicates that the imaging region is a foot, the icon 634 indicates that the imaging region is a lung, and the icon 636 indicates that the imaging region is a rib. The icon 638 indicates that the imaging region is the stomach. Then, for example, when the doctor 38 operates the mouse 336 and clicks on the icon 630, the display content is switched to the display content of FIG. 24, and a more detailed list of techniques related to hand imaging is displayed.

  The above is the description regarding the first embodiment.

  Next, a second embodiment will be described.

  In step 81 of FIG. 21 after step S16 of FIG. 15, the operator 32 finds out from the site the subject 18 that needs to be taken a radiographic image due to injury or the like at the disaster site, for example. Next, the operator 32 regards the injured part of the subject 18 as an imaging part, and directs the web camera 30 to the injured part (imaging part) to shoot a camera image of the subject 18 including the injured part ( Step S82). In step S83, the control processing unit 222 transmits the camera image taken in step S82 to the medical institution 40 by wireless communication via the communication unit 218, the antenna 216, and the network 36.

  When the control processing unit 226 receives the camera image via the antenna 102 and the communication unit 104 (step S84), the control processing unit 226 switches the display content of the screen 400 of the display unit 112 to the content of FIG.

  In FIG. 93, the field-side image display area 404 is assigned to the left area of the window 402, and the shooting menu display area 406 is assigned to the right area. The shooting menu display area 406 displays an order information editing area 600 for changing (setting or editing) order information.

  In the order information editing area 600, a text box 602 for inputting the ID of the subject 18 shown in the camera image, a text box 604 for inputting the name of the subject 18, and a gender of the subject 18 are entered. A text box 606 for inputting the age of the subject 18, a text box 610 for inputting an imaging method for the subject 18, a text box 612 for inputting an imaging part of the subject 18, Selection buttons 614 and 616 for selecting whether the input content is OK or NG are displayed.

  Accordingly, in step S85, the doctor 38 operates the operation unit 114 and the mouse 336 to input necessary contents in the text boxes 602 to 612 while viewing the camera image of the subject 18 displayed in the on-site image display area 404. If the input content is satisfactory, the mouse 336 is operated and the selection button 614 is clicked. As a result, order information is set (step S86), and procedures according to the set order information are displayed in a list in the shooting menu display area 406 (step S18, FIG. 23 and FIG. 24).

  If the input content is to be corrected, the content input in each of the text boxes 602 to 612 can be deleted by clicking the selection button 616. Further, since the portable information terminal 34 is provided with the microphone 80 and the speaker 78, and the console 106 is also provided with the microphone 122 and the speaker 118, the doctor 38 inputs the text boxes 602 to 612 to the operator 32. It is also possible to inquire about information related to the contents (for example, the name of the subject 18), and the operator 32 can answer the doctor 38 in response to the inquiry.

  Furthermore, in the disaster scene, there may be many injured persons due to injuries, and it is necessary for the operator 32 to respond quickly to each injured person. May not be obtained, and therefore it may be difficult to fill all the text boxes 602-612. In such a case, the text box that cannot be filled is left as it is, and only the text box that can be filled needs to be input.

  In the second embodiment, since it is necessary to change the shooting menu while viewing the camera image of the site, the size of the site-side image display area 404 and the size of the shooting menu display area 406 in the window 402 are substantially the same. The size is desirable.

  The above is the description regarding the second embodiment.

  Next, a third embodiment will be described.

  In the second embodiment described above, order information is set (step S86), a shooting menu is set based on the order information (steps S18 to S21), and the set shooting menu is transferred from the medical institution 40 to the portable information terminal 34. In step S91 of FIG. 22 after the transmission (steps S22 and S23) and the operator 32 confirms the photographing menu (step S24), the operator 32 confirms that the content of the confirmed photographing menu is an injury to the subject 18. It is determined whether or not the content is appropriate for the location (imaging site).

  Specifically, as shown in FIG. 94, selection buttons 620 and 622 for selecting whether or not the setting contents are OK are displayed below the shooting menu display area 434, and the operator 32 Then, it is determined whether or not the injured subject 18 corresponds to the content of the shooting menu. If the contents of the shooting menu are acceptable, the operator 32 operates the operation unit 60 and clicks the selection button 620 (step S91: YES). As a result, the control processing unit 222 performs the process of step S25, and sends a confirmation notification indicating that the set shooting menu content is OK via the communication unit 218, the antenna 216, and the network 36 to the medical institution. 40, and the display content of the window 432 is switched from the content of FIG. 94 to the content of FIG. 95, and the characters “OK notification sent to hospital” are displayed in the imaging menu display area 434.

  When the control processing unit 226 of the console 106 receives the confirmation notification via the antenna 102 and the communication unit 104 (step S26), the display content of the screen 400 of the display unit 112 is switched to the content of FIG. As a result, the doctor 38 can confirm that the operator 32 has confirmed the contents of the shooting menu and that the set shooting menu is OK.

  On the other hand, when the injured subject 18 does not correspond to the content of the shooting menu (step S91: NO), the operator 32 operates the operation unit 60 and clicks the selection button 622 (step S91: NO). Step S92). As a result, the control processing unit 222 sends a confirmation notification (NG notification) indicating that the content of the set shooting menu does not correspond to the subject 18 (NG) via the communication unit 218, the antenna 216, and the network 36. In addition to transmitting to the medical institution 40 by wireless communication, the display content of the window 432 is switched from the content of FIG. 94 to the content of FIG. 97 and the characters “NG notification sent to the hospital” are displayed in the imaging menu display area 434 ( Step S93).

  When the control processing unit 226 of the console 106 receives the NG notification via the antenna 102 and the communication unit 104 (step S94), the display content of the screen 400 of the display unit 112 is switched to the content of FIG. 98 (step S95). As a result, the doctor 38 can confirm that the operator 32 has confirmed the contents of the photographing menu, and that the contents of the set photographing menu are NG, and resetting is necessary. In this case, the console 106 may warn that resetting is necessary by outputting sound from the speaker 118 together with the display by the display unit 112 (step S95).

  In the description of the third embodiment, the case where the site side determines whether or not the content of the shooting menu is appropriate has been described, but only for individual items such as order information, procedures, or shooting conditions. It may be determined on the site side and the determination result may be notified to the medical institution 40. For example, when it is determined on the site side whether or not the procedure has an appropriate content, the display unit 112 of the console 106 displays the characters “procedure OK” or “procedure NG” on the screen 400 of the display unit 112. Show it.

  As described above, according to the radiographic image capturing system 11, the radiographic image capturing method, and the image display method according to the present embodiment, the following effects can be obtained.

  According to the radiographic image capturing system 11, the radiographic image capturing method, and the image display method according to the present embodiment, the on-site camera is connected from the communication unit 218 of the portable information terminal 34 to the communication unit 104 of the medical institution 40 before the radiographic image is captured. While an image (an optical image captured by the web cameras 30 and 330) is transmitted, a communication menu and a camera image of the medical institution 40 (an optical image captured by the web camera 116) are transmitted from the communication unit 104 to the communication unit 218. The Accordingly, the display unit 112 of the console 106 can display at least one of the shooting menu and the on-site camera image, while the display unit 64 of the portable information terminal 34 displays the shooting menu and the on-site camera image. At least one of the camera image and the camera image of the medical institution 40 can be displayed.

  Therefore, the doctor (or radiologist) 38 waiting at the standby place such as the medical institution 40 properly instructs the operator 32 at the site while viewing the camera image of the site displayed on the display unit 112. (For example, an instruction for positioning the subject 18) can be performed. If the shooting menu is also displayed on the display unit 112, the doctor 38 confirms (monitors) whether or not the operator 32 is performing work according to the contents of the shooting menu while viewing the on-site camera image. You can also.

  On the other hand, the operator 32 can grasp what kind of radiographic image is to be taken on the subject 18 by looking at the photographing menu displayed on the display unit 64, and the operator 32 can select an appropriate one according to the photographing menu. It is possible to perform a simple operation (for example, positioning of the subject 18). Moreover, if the camera image of the site is displayed on the display unit 64, the operator 32 can easily check the status of the site. Furthermore, if the camera image of the medical institution 40 is displayed, the operator 32 can recognize that the medical institution 40 grasps the situation at the site, and can perform the work at the site with peace of mind. Can do.

  In addition, after the radiographic image is captured, the on-site camera image and radiographic image are transmitted from the communication unit 218 to the communication unit 104. Thereby, the display unit 112 of the console 106 can display at least one of the imaging menu, the on-site camera image, and the radiation image. On the other hand, the display unit 64 of the portable information terminal 34 can display at least one of an imaging menu, an on-site camera image, a medical institution camera image, and a radiation image.

  Thus, the doctor 38 can determine whether an appropriate radiographic image (an image suitable for interpretation diagnosis) is obtained according to the imaging menu while viewing the radiographic image displayed on the display unit 112. Also, the operator 32 can know whether or not the radiographic image has been properly captured by viewing the radiographic image displayed on the display unit 64.

  Therefore, according to the present embodiment, when the doctor 38 is standing by at a waiting place (medical institution 40) where the subject 18 cannot be directly viewed, the doctor 38 looks at the display content of the display unit 112 while viewing the display contents. The operator 32 can be instructed to take a radiation image in real time. Therefore, it is possible to perform photographing on the subject 18 without the doctor 38 going directly to the site.

  In addition, as described above, the display unit 112 captures a radiographic image because signals such as an imaging menu, an on-site camera image, a medical institution camera image, and a radiographic image are transmitted and received between the communication units 104 and 218. The information that the doctor 38 wants to see at the present time can be displayed as large as possible on the screen 400 according to the situation (before and after the imaging). Accordingly, the information that the operator 32 wants to see at the present time can be displayed on the screen 430 as large as possible. Thereby, the doctor 38 can perform an appropriate instruction | indication with respect to the operator 32, and can determine efficiently etc. whether the suitable radiographic image was obtained. Further, the operator 32 can efficiently perform work on the site according to the display content of the display unit 64 (instructions from the doctor 38, etc.).

  As described above, the information that the doctor 38 wants to see is greatly displayed on each screen 400 and the information that the operator 32 wants to see is greatly displayed on each screen 430 according to the radiographic image capturing situation. The screens 400 and 430 may display the same display contents, or display different display contents.

  For example, when positioning the subject 18, it is necessary to adjust the position of the imaging part while determining whether the imaging part of the subject 18 is within the outer frame of the guide line 46. It is desirable that the same display contents are displayed on the screens 400 and 430. In this case, if a camera image including the imaging region (right hand) of the subject 18 and the vicinity (right arm) of the imaging region is displayed, the doctor 38 gives an appropriate instruction while grasping the entire imaging region. 32, and the operator 32 can perform a predetermined operation while grasping the entire imaging region. As a result, it is possible to efficiently perform imaging preparation.

  On the other hand, when setting the imaging menu or after radiographic imaging, the screens 400 and 430 may display different display contents as described above.

  In the present embodiment, on the site side, the web camera 330 is configured integrally with the radiation source main body 16 and the web camera 30 is configured integrally with the portable information terminal 34. And the assembly and accommodation of the radiation imaging apparatus 10 at the site becomes easy.

  Furthermore, in the present embodiment, the web camera 330 captures at least one of the cassette body 22 and the subject 18, and the web camera 30 captures at least one of the cassette body 22, the radiation source body 16, and the subject 18. The web camera 116 photographs the doctor 38.

  By displaying the camera image of the web camera 330 and the camera image of the web camera 30 on the display unit 64, the operator 32 does not have to directly view the subject 18, the cassette body unit 22, and the radiation source body unit 16. The status of the subject 18, the cassette body 22, and the radiation source body 16 can be grasped only by confirming the display content of the display unit 64. Further, since the camera image of the web camera 116 is displayed on the display unit 64, the operator 32 can recognize that the doctor 38 is looking at the site, and can perform the work at the site with peace of mind. Can do. Furthermore, the camera image of the web camera 330 and the camera image of the web camera 30 are displayed on the display unit 112, so that the doctor 38 does not go directly to the site, but the subject 18, the cassette body unit 22, and the radiation source body. It is possible to accurately grasp the situation of the site including the unit 16 and to give an appropriate instruction to the operator 32.

  Moreover, the display units 64 and 112 display the camera images of the web cameras 30 and 330 or the imaging menu larger than other images until the radiographic image is captured. Thereby, it is possible to efficiently perform the positioning of the subject 18 and the setting of the imaging menu performed before the radiographic image is captured.

  In addition, as described above, the display unit 112 displays as much information as possible on the screen 400 as much as possible on the screen 400 according to the radiographic image capturing state, and the display unit 64 wants the operator 32 to view the information. Information is displayed on the screen 430 as large as possible. Specifically, the following display is performed.

  When the procedure and the shooting conditions are set on the console 106 based on the order information, the display unit 112 displays the shooting menu larger than the other images. This makes it easier to set the shooting menu. On the other hand, the display unit 64 displays the technique larger than the order information and the shooting conditions in the shooting menu received via the communication unit 218. Thereby, it is possible to reliably instruct the operator 32 of the radiographic image capturing technique performed this time.

  In addition, at least the display unit 112 desirably displays the radiographic image larger than other images after the radiographic image is captured. This makes it possible to easily determine whether an appropriate radiographic image has been obtained according to the imaging menu. In this case, if the radiographic image of the imaging region (right hand) is displayed larger (wider) than the camera image including the imaging region and the vicinity of the imaging region (a part of the right arm), the radiation It is possible to accurately determine whether the image is an image suitable for interpretation diagnosis.

  Furthermore, when the radiographic image is re-photographed, each of the display units 64 and 112 may display a camera image taken by the web cameras 30 and 330 or an imaging menu larger than other images. As a result, it is possible to reduce the time required for shooting preparation for re-shooting.

  When re-imaging is not required or when the image is captured only once, each display unit 64, 112 displays a larger image without displaying the imaging menu after the radiographic image is captured. Also good.

  In the present embodiment, the authentication processing unit 344 determines whether or not the subject 18 reflected in the web cameras 30 and 330 matches the subject 18 indicated by the order information. It is possible to avoid the occurrence of incorrect tying and the occurrence of radiographic image capturing errors.

  In this case, the web cameras 30 and 330 photograph the face of the subject 18, and the authentication processing unit 344 detects the face subject reflected in the camera image based on the camera image of the face photographed by the web cameras 30 and 330. 18 and whether or not the subject 18 indicated by the order information matches. By performing the authentication process using such a face image, it is possible to reliably determine whether or not the subject 18 reflected in the camera image is a genuine subject.

  More preferably, the camera image of the face is an image of the face including the pupil of the subject 18, and the authentication processing unit 344 is reflected in the camera image based on the camera image including the pupil photographed by the web cameras 30, 330. It is only necessary to determine whether or not the subject 18 having a closed pupil matches the subject 18 indicated by the order information. By performing the pupil authentication process, it is possible to more accurately perform the authentication process between the subject 18 reflected in the camera image and the subject 18 indicated by the order information, and the occurrence of incorrect association due to the mistake of the subject 18 In addition, it is possible to reliably avoid occurrence of radiographic image capturing mistakes.

  Furthermore, each display unit 64 and 112 may display at least one of the camera images of the web cameras 30 and 330 and the shooting menu together. Accordingly, it is possible to easily determine whether or not the subject 18 (imaging part) reflected in the web cameras 30 and 330 corresponds to the contents of the imaging menu.

  Furthermore, the display units 64 and 112 may display at least the radiographic image and the radiographing menu after the radiographic image is captured. Thereby, it can be performed efficiently whether the suitable radiographic image was obtained according to the imaging | photography menu.

  Moreover, according to the radiographic image capturing system 11, the radiographic image capturing method, and the image display method according to the present embodiment, as shown in the second example, before capturing a radiographic image, the on-site communication unit 218 performs medical treatment. The on-site camera image is transmitted to the communication unit 104 at 40 (standby place), and the console 106 sets (changes) the contents of the shooting menu according to the situation of the subject 18 reflected in the on-site camera image, and sets the setting. The subsequent shooting menu is transmitted from the communication unit 104 to the communication unit 218. As a result, the portable information terminal 34 controls the radiation source main body 16 and the cassette main body 22 based on the imaging menu after setting, and causes the subject 18 to take a radiographic image.

  As described above, according to the present embodiment, before the radiographic image is captured, the radiographing menu is set (rewritten) according to the subject 18, and the radiographic image is captured based on the radiographic menu after the setting. Appropriate radiographic images can be acquired.

  Further, on the mobile information terminal 34 side, before the radiographic image is captured, whether or not the subject 18 reflected in the camera image captured by the web cameras 30 and 330 matches the subject 18 indicated by the imaging menu. The control processing unit 222 transmits the determination result to the communication unit 104 via the communication unit 218. Thereby, the doctor 38 can grasp whether or not the set shooting menu is a shooting menu corresponding to the subject 18 in the field.

  In this case, if the determination result indicates that the subject 18 reflected in the camera image matches the subject 18 indicated by the shooting menu, the display unit 112 displays the determination result on the screen 400. The doctor 38 can easily grasp the determination result.

  In addition, when the doctor 38 operates the exposure switch 120 (or clicks on the icon 572) after notifying the determination result indicating that both match, the control signal generation unit 346 sends the communication signal from the communication unit 104 to the communication unit 218. The portable information terminal 34 transmits the exposure control signal, and controls the radiation source main body 16 and the cassette main body 22 based on the synchronization control signal based on the received exposure control signal and the imaging menu, and the radiographic image Let's shoot. Thereby, radiographic imaging can be reliably performed.

  On the other hand, as shown in the third embodiment, when the determination result indicates that the subject 18 reflected in the camera image does not match the subject 18 indicated by the shooting menu, the control processing unit 222 May display the determination result on the screen 400 of the display unit 112 and warn with a sound from the speaker 118. As a result, it is possible to notify the doctor 38 that the shooting menu does not correspond to the subject 18 at the site, and as a result, it is possible to immediately start work such as changing the shooting menu according to the subject 18. Become.

  In this case, on the console 106 side, at least one of order information, procedure, and shooting conditions is changed in the shooting menu according to the situation of the subject 18 reflected in the camera image. Thereby, it is possible to set an accurate shooting menu according to the subject 18.

  Here, when the subject 18 reflected in the camera image is different from the subject 18 indicated by the order information, or when the imaging region is different even if it coincides with the subject 18 indicated by the order information, the order information and technique The contents of the shooting menu may be changed in the order of the shooting conditions. If the subject 18 is different or the imaging region is different, the order information itself needs to be changed. Therefore, by changing the contents of the imaging menu in the order of order information, technique, and imaging conditions, a more accurate imaging menu can be obtained. Can be set.

  If the technique differs even if the subject 18 reflected in the camera image matches the subject 18 indicated by the order information, the contents of the shooting menu may be changed in the order of the technique and shooting conditions. Even in this case, a more accurate shooting menu can be set.

  Further, at least the on-site camera image and radiographic image may be transmitted from the communication unit 218 to the communication unit 104 so that the display units 64 and 112 can display at least one of the camera image, radiographic image, and imaging menu. . Accordingly, the doctor 38 can set an accurate shooting menu corresponding to the subject 18 while confirming the display content of the display unit 112, while the operator 32 displays the display content of the display unit 64. By confirming, it is possible to easily determine whether or not the shooting menu corresponds to the subject 18.

  Then, when the shooting menu is changed, the camera image and the shooting menu are displayed together on the display unit 112 so that the on-site camera image is displayed larger than the other images. As a result, the burden of setting the shooting menu by the doctor 38 can be reduced.

  Furthermore, according to the radiographic image capturing system 11, the radiographic image capturing method, and the image display method according to the present embodiment, an on-site camera image (an optical image captured by the web cameras 30, 330) and the communication unit 104 from the communication unit 218 and While the radiation image is transmitted, at least an imaging menu is transmitted from the communication unit 104 to the communication unit 218. The console 106 or the portable information terminal 34 associates at least the imaging menu, the radiation image, and the on-site camera image, and stores them in the memories 224 and 228.

  As described above, after capturing a radiographic image, at least the radiographing menu, the radiographic image, and the on-site camera image are associated with each other and stored in the memories 224 and 228, so that information on the on-site subject 18 and the radiographic image of the subject 18 are obtained. Can be accurately performed, and as a result, interpretation diagnosis by the doctor 38 can be performed appropriately and efficiently.

  In this case, the web camera 330 captures the cassette body 22 and the imaging part of the subject 18 positioned with respect to the cassette body 22, and the webcam 30 captures the subject 18 or the cassette 18. The main body 22, the imaging part of the subject 18 positioned with respect to the cassette main body 22 and the radiation source main body 16 are imaged. Since the radiographic image of the subject 18 and the camera image related to the radiographic image (for example, the optical image of the imaging region) are linked, the interpretation diagnosis by the doctor 38 is further facilitated.

  Further, as described above, the authentication processing unit 344 performs biometric authentication processing (pupil authentication processing) using the face image (including the pupil) of the subject 18 in the camera image captured by the web camera 30. As a result, it is possible to prevent the linked information from being linked, and as a result, it is possible to improve the reliability of the linked information.

  Further, the authentication processing unit 344 determines whether or not the subject 18 reflected in the camera image matches the subject 18 indicated by the order information, and transmits the authentication result from the communication unit 104 to the communication unit 218. The display unit 64 of the portable information terminal 34 displays the authentication result received via the communication unit 104 on the screen 430. As a result, if the subject 18 reflected in the camera image associated with the subject 18 does not match the subject 18 indicated by the shooting menu, the operator 32 finds the authentic subject 18 indicated by the shooting menu again from the scene. Is also possible.

  In addition to the above information (images), the console 106 or the portable information terminal 34 may associate the camera image of the web camera 116 and store it in the memories 224 and 228. As a result, it is possible to associate the information of the doctor 38 who instructed the radiographic image capturing.

  The display units 64 and 112 may display the imaging menu, the radiation image, the on-site camera image, and the camera image of the web camera 116 side by side. As a result, the images and information to be linked are displayed together, so that the doctor 38 and the operator 32 can easily grasp what information is linked.

  In addition, the memory in which the associated information is stored is preferably the memory 228 of the console 106, the memory 224 of the portable information terminal 34, the memory card 92, or the USB memory 334. In this case, the linked information is preferably stored after being encrypted.

  The memory card 92 is detachable from the card slot 94 of the portable information terminal 34, and the USB memory 334 is detachable from the USB terminals 84, 88, 90. When storing the encrypted post-link information in the attached memory card 92 and / or USB memory 334, the control processing unit 222 has completed the storage process for the memory card 92 and / or USB memory 334 Later, a notification for permitting removal of the memory card 92 and / or the USB memory 334 from the portable information terminal 34 may be displayed on the display unit 64 or may be output as a sound from the speaker 78.

  Alternatively, when the portable information terminal 34 is provided with a lock mechanism (not shown) for preventing the memory card 92 and / or the USB memory 334 attached to the portable information terminal 34 from being removed, After the storage process for the card 92 and / or the USB memory 334 is completed, the memory card 92 and / or the USB memory 334 may be removable from the portable information terminal 34 by releasing the extraction preventing function by the lock mechanism. . Even in this case, the control processing unit 222 may cause the display unit 64 to display a notification indicating that the extraction is possible, or may output the notification from the speaker 78 as a sound.

  In the present embodiment, in addition to the above effects, the following effects are also obtained.

  The web camera 30 (integrated in the portable information terminal 34) integrated with the portable information terminal 34 or the radiation source main body 16 (radiation) is integrated with the portable information terminal 34 at a disaster site or home nursing site. The web camera 330 (incorporated in the source body section 16) images at least the cassette body section 22 (the guide line 46 corresponding to the radiation detector 20 accommodated therein), and the communication section 218 includes the web cameras 30 and 330. The photographed camera image is transmitted to the communication unit 104 provided in the medical institution 40 via the network 36.

  As a result, the doctor (or radiology engineer) 38 who is waiting at the medical institution 40 (remotely) who cannot directly view the subject 18 can perform a disaster or home nursing based on each camera image received by the communication unit 218. It is possible to instruct the operator 32 of the radiation image capturing apparatus 10 at the site of the subject to capture the subject 18 in real time. Therefore, even if the doctor 38 does not go directly to the disaster site or home nursing site, that is, he / she is not a licensed medical radiographer (has no authority to irradiate the subject 12 with radiation 12). Even without this, it is possible to perform photographing on the subject 18.

  In this case, the outer frame of the guide line 46 corresponds to the irradiation field of the radiation 12 when the distance between images is set to SID, and the web camera 30 images the outer frame of the guide line 46. Therefore, the doctor 38 looks at the camera image of the web camera 30 and if the imaging region of the subject 18 is within the outer frame of the guide line 46 (if it is reflected inside the guide line 46), the doctor 38 On the other hand, it can be determined that an appropriate radiation image can be obtained by irradiating the radiation 12. On the other hand, when the imaging region of the subject 18 is off the guide line 46 or when only a part of the imaging region is inside the guide line 46, the doctor 38 in this state applies radiation 12 to the subject 18. It can be determined that a desired radiation image cannot be obtained.

  In this way, the web camera 30 captures the guide line 46, and the doctor 38 looks at the camera image of the web camera 30 (while monitoring) and the imaging region of the subject 18 is within the outer frame of the guide line 46. By determining whether or not, it is possible to determine whether or not an appropriate radiation image can be obtained. As a result, even when the doctor 38 is in a state where the subject 18 and the operator 32 cannot be directly viewed, the doctor 38 can give an instruction for appropriate photographing preparation to the operator 32 who is visiting the site.

  Further, as described above, the web camera 30 is built in the upper surface side of the lid 66 of the portable information terminal 34 and is configured integrally with the portable information terminal 34. In this case, the web camera 30 photographs the radiation source main body 16, the subject 18, and the cassette main body 22 including the guide line 46 in the state shown in FIG. 1, FIG. 2, and FIGS. A camera image including the guide line 46 can be obtained with certainty.

  Further, as described above, the web camera 330 is also built in the vicinity of the output location of the radiation 12 in the radiation source body 16 and is configured integrally with the radiation source body 16. In this case, the web camera 330 shoots the imaging part of the subject 18 and the cassette body 22 including the guide line 46 in the state shown in FIGS. 1, 2, 3B, and 4 to 6. A camera image including the guide line 46 can be reliably obtained.

  In addition, the operator 32 issues an instruction to the subject 18 while operating the portable information terminal 34 and positions the subject 18 with respect to the guide line 46, so that the radiation source can be displayed while the operator 32 operates the portable information terminal 34. Even if the subject 18 is irradiated with the radiation 12 from 14, it is possible to reliably avoid exposure of the operator 32.

  Further, the communication unit 218 of the portable information terminal 34 incorporating the web camera 30 transmits the camera image to the medical institution 40 via the antenna 216 and the network 36, so that the camera image is reliably transmitted to the medical institution 40. Can do.

  In this case, the control processing unit 222 of the portable information terminal 34 generates a synchronization control signal for synchronizing the output of the radiation 12 from the radiation source 14 and the conversion from the radiation 12 to the radiation image in the radiation detector 20. The communication unit 218 transmits the synchronization control signal to the communication unit 136 of the radiation source main body unit 16 and the communication unit 170 of the cassette main body unit 22, so that the radiation source 14, the radiation detector 20, and The time synchronization can be surely taken.

  Furthermore, since the camera images and radiographic images of the web cameras 30 and 330 described above are transmitted from the portable information terminal 34 to the medical institution 40 by wireless communication via the network 36, the doctor 38 in the medical institution 40 can use the console 106. By visually recognizing the camera image and the radiation image displayed on the display unit 112, it is possible to give an appropriate instruction to the operator 32 and the subject 18 at the site.

  Further, the console 106 is provided with an exposure switch 120 for starting output of the radiation 12 from the radiation source 14. In this case, when the doctor 38 turns on the exposure switch 120 based on the camera image displayed on the display unit 112, the control processing unit 226 of the console 106 starts to output the radiation 12 from the radiation source 14. An exposure control signal is generated and transmitted from the communication unit 104 to the portable information terminal 34 via the network 36. Accordingly, the control processing unit 222 of the portable information terminal 34 generates a synchronization control signal based on the exposure control signal received by the communication unit 218 and transmits the synchronization control signal to the radiation source main body unit 16 and the cassette main body unit 22.

  Accordingly, the doctor 38 can perform a photographing action in real time while monitoring the subject 18 in the medical institution 40 where the subject 18 cannot be directly viewed without visiting a disaster site or home nursing site. .

  Specifically, when the preparation for photographing is completed, the doctor 38 determines that the photographing switch of the subject 18 is reflected in the outer frame of the guide line 46 in the camera images of the web cameras 30 and 330. On the subject 18 to start radiographic image capturing. On the other hand, in the camera image, the imaging region of the subject 18 is not reflected in the outer frame of the guide line 46, or one of the imaging regions is detected. If only part of the image is reflected in the outer frame, the exposure switch 120 is not turned on, and the operator 32 is instructed to redo the preparation for photographing.

  As a result, it is possible to easily and reliably perform a photographing action by remote operation from the medical institution 40.

  In addition, by giving an instruction from the doctor 38 to the operator 32 at the site by displaying the screen of the display unit 64 or by outputting sound from the speaker 78, the instruction to the operator 32 at the site can be accurately and efficiently transmitted. .

  Furthermore, if the camera image output from the web cameras 30 and 330 is a moving image or a still image taken intermittently at a predetermined time interval, the doctor 38 instructs the operator 32 in a timely manner. Can be issued. Of course, even if the camera image is a still image taken at a predetermined time in the shooting preparation stage, the doctor 38 can determine whether or not the shooting is possible.

  Further, since the web cameras 30 and 330 are optical cameras, it is possible to display easy-to-view camera images for the doctor 38.

  In the above description, the case where the instruction content from the doctor 38 is transmitted to the operator 32 by both the screen display by the display unit 64 and the sound output from the speaker 78 has been described. It is also possible to transmit the instruction content only by display or only by sound output from the speaker 78.

  In the above description, the instruction content is transmitted from the doctor 38 to the operator 32, and the operator 32 positions the subject 18 according to the instruction content. In this case, since the subject 18 is also listening to the sound output from the speaker 78, the instruction contents may be directly transmitted from the doctor 38 to the subject 18 to cause the subject 18 to be positioned. Alternatively, the subject 18 may check the instruction content displayed on the display unit 64 before positioning, and then perform positioning with respect to the guide line 46 according to the instruction content.

  Further, in the above description, the case where the synchronization control signal is transmitted from the portable information terminal 34 to the radiation source main body 16 and the cassette main body 22 has been described. Instead, the synchronization is performed by the control signal generation unit 346 of the console 106. A control signal may be generated, and the synchronization control signal may be transmitted to the radiation source main body 16 and the cassette main body 22 via the network 36 and the portable information terminal 34.

  Furthermore, instead of the configuration in which the cassette body 22 is activated when the switch 50 is turned on, the operation unit 60 is operated by the operator 32, the operation unit 114 is operated by the doctor 38, or the handle 310 is grasped by the operator 32. The cassette body 22 may be activated due to the output of a detection signal from the accompanying touch sensor 312.

  In addition, by providing the handle 310 that the operator 32 grips at a location on the opposite side to the output location of the radiation 12 in the radiation source main body 16, the operator 32 holds the handle 310 with one hand, The radiation source main body 16 in which the web camera 330 is built is directed toward the subject 18 and the cassette main body 22, and the portable information terminal 34 is operated with the other hand while viewing the display unit 64. In this case, since the camera image captured by the web camera 330 is displayed on the display unit 64, the operator 32 moves the radiation source main body unit 16 to a desired position while viewing the camera image, and then the subject 18. Can be positioned. Even when the radiation 12 is output while the operator 32 is gripping the handle 310, irradiation of the radiation 12 to the operator 32 (exposure of the operator 32) can be reliably avoided.

  In particular, the application of such an embodiment is effective in a disaster site where there are many obstacles around. That is, at the disaster site, there are a lot of obstacles, and furthermore, it is difficult to move the subject 18 due to injury or the like. Therefore, the radiation source main body 16 and the cassette main body 22 are fixed in a predetermined place, and the radiation source It is practically difficult to guide the subject 18 between the main body 16 and the cassette main body 22. Therefore, there are many cases where the radiation source main body 16 and the cassette main body 22 must be arranged in accordance with the subject 18. Therefore, even if the operator 32 can point the radiation source main body 16 toward the subject 18, it is difficult for the operator 32 to directly view the subject 18 due to the presence of an obstacle, and therefore the operator 32 positions the subject 18. Is not easy.

  Therefore, in the present embodiment, when the operator 32 holds the handle 310 with one hand and directs the radiation source main body 16 toward the subject 18 and the cassette main body 22 at the disaster site, the webcam 330 The cassette body 22 is photographed, and the camera image is displayed on the display unit 64. Therefore, the operator 32 can easily operate the portable information terminal 34 with the other hand while viewing the camera image displayed on the display unit 64, or can easily adjust the position of the radiation source body 16 and the positioning of the subject 18. Can be done.

  Since the handle 310 is provided with a capacitive or resistive touch sensor 312, the radiation source control unit 138 or the control processing unit 222 determines whether the radiation source main body unit 16 is based on the detection signal. Or the cassette body 22 can be operated.

  Further, the portable information terminal 34 is electrically connected to the radiation source main body 16 and the cassette main body 22 via a USB cable (not shown), and the battery 220 of the portable information terminal 34 is connected to the battery of the radiation source main body 16. Alternatively, the battery 166 of the cassette 134 or the cassette body 22 may be reliably charged. Thus, in addition to charging the batteries 134 and 166, signal transmission and reception can be performed reliably. That is, it is possible to reliably transmit a synchronization control signal and imaging conditions from the portable information terminal 34 to the radiation source main body 16 and the cassette main body 22 and to transmit a radiation image from the cassette main body 22 to the portable information terminal 34. it can.

  In addition, when charging the batteries 134 and 166, it is only necessary that the batteries 134 and 166 can be charged by a charge amount corresponding to at least the number of images of the subject 18. Thereby, it is possible to reliably perform shooting for the number of shots during shooting.

  Alternatively, the batteries 134 and 166 may be charged only during the time period before the radiographic image is captured. As a result, the batteries 134 and 166 are not charged at the time of radiographing and at the time of transmission of radiographic images after radiography, so that noise caused by charging is superimposed on the charge signal (analog signal) during radiographing, or It is possible to avoid the noise from being superimposed on the radiographic image during transmission of the radiographic image.

  Further, in the above description, radiographic imaging starts when the exposure switch 120 is turned on or the icon 572 is clicked. However, the imaging only needs to be started in accordance with an instruction from the doctor 38. The exposure button (exposure switch) may be displayed on the screen of the display unit 112 and imaging may be started by the doctor 38 pressing the exposure button, or one button of the operation unit 114 may be started. May be dedicated to the exposure switch, and shooting may be started by turning on this button.

  Furthermore, although the cassette body 22 has the shape of a housing, the radiation detector 20 and the like may have a flexible sheet-like shape. Since the sheet can be wound into a roll, further reduction in size and weight of the entire radiographic imaging apparatus 10 including the cassette body 22 can be realized.

  Further, when charging the batteries 134 and 166 from the battery 220, one of the three batteries is regarded as a power source for the radiation imaging apparatus 10 as a whole, and the remaining two batteries are charged from the one battery. Also good.

  Furthermore, in the above description, the case where the camera image captured by the web camera 30 is transmitted from the communication unit 218 of the portable information terminal 34 to the communication unit 104 of the medical institution 40 via the network 36 has been described. However, the present invention is not limited to this.

  For example, the communication unit 136 of the radiation source main unit 16 and the communication unit 170 of the cassette main unit 22 have a function capable of communicating with the communication unit 104 via the network 36, and camera images from these communication units 136 and 170 are provided. May be sent.

  By providing the communication units 136 and 170 with such a communication function, a radiation image can be directly transmitted from the communication unit 170 to the communication unit 104 via the network 36, or the communication unit 136 and the network 36 can be transmitted from the communication unit 170. It is also possible to transmit a radiation image to the communication unit 104 via the network.

  Further, transmission / reception of all signals between the radiographic imaging apparatus 10 and the medical institution 40 is performed between the communication unit 136 and the communication unit 104, or between the communication unit 170 and the communication unit 104. It is also possible to do this.

  That is, in the present embodiment, the portable information terminal 34, the radiation source main body 16 and the cassette main body 22 are connected by radio within the same link, and a cable (USB cable) for transmitting and receiving signals is unnecessary. Therefore, there is no possibility that the operation of the operator 32 will be hindered. Therefore, the operator 32 can perform his / her work efficiently. Further, by eliminating the need for a cable, the number of parts of the radiation image capturing apparatus 10 is reduced, and assembly work at the site is facilitated.

  Furthermore, as described above, since the portable information terminal 34, the radiation source main body 16 and the cassette main body 22 exist in the same link, the camera image and the radiation between the communication unit 104 of the medical institution 40 Transmission and reception of signals such as images may be performed via any one of the communication units 136, 170, and 218.

  In the present embodiment, signals may be transmitted and received by optical wireless communication using infrared rays or the like instead of wireless communication.

  Furthermore, in the above description, signals are transmitted and received between the radiographic imaging apparatus 10 and the medical institution 40 by wireless communication via the network 36, but this embodiment is limited to this. However, it goes without saying that signals may be transmitted and received by other communication modes.

  That is, signals may be transmitted / received between the radiographic image capturing apparatus 10 and the medical institution 40 by wired communication via the network 36.

  Alternatively, signals may be transmitted / received via the network 36 by wired communication and wireless communication. Specifically, if a repeater (relay device) is present in the network 36, signals are transmitted and received to the repeater by wired communication (or wireless communication), and the point beyond the repeater is wireless communication (or wireless). Communication).

  In addition, another portable terminal such as a cellular phone is electrically connected to the portable information terminal 34, and the communication function of the other portable terminal is used to connect with the medical institution 40, the radiation source body 16 and the cassette. Signals may be transmitted to and received from the main body 22. In this case, the communication unit of the other portable terminal functions as the communication unit 218.

  Furthermore, the present embodiment can also be applied to a case where a radiation image is acquired using an optical readout radiation detector. In this light readout type radiation detector, when radiation enters each solid detection element, an electrostatic latent image corresponding to the dose is accumulated and recorded in the solid detection element. When reading the electrostatic latent image, the radiation detector is irradiated with reading light, and the value of the generated current is acquired as a radiation image. Note that the radiation detector can erase and reuse the radiation image, which is the remaining electrostatic latent image, by irradiating the radiation detector with erasing light (see Japanese Patent Application Laid-Open No. 2000-105297).

  Furthermore, in the radiographic imaging device 10, in order to prevent the risk of blood and other germs adhering, for example, the entire device has a waterproof and sealing structure, and is sterilized and washed as necessary. One radiographic imaging device 10 can be used repeatedly.

  Furthermore, in this embodiment, as shown in FIG. 99, a cradle 230 that charges each of the batteries 134, 166, and 220 (see FIG. 12) is preferably disposed at a necessary location in the medical institution 40.

  In this case, the portable information terminal 34 and the cradle 230 are electrically connected by a USB cable 234 having connectors 236 and 238, and the radiation source body 16 and the cradle 230 are connected by USB cables having connectors 58 and 82. 24 and the cassette body 22 and the cradle 230 are electrically connected by a USB cable 26 having connectors 52 and 86.

  The cradle 230 performs not only charging of the batteries 134, 166, and 220 but also transmitting and receiving necessary information to and from the console 106 and RIS in the medical institution 40 using the wireless communication function or the wired communication function of the cradle 230. You may do it. The information to be transmitted / received can include a radiographic image recorded in the radiographic imaging device 10.

  In addition, a display unit 232 is provided in the cradle 230 so that the display unit 232 displays necessary information including a charged state of the radiographic image capturing apparatus 10 and a radiographic image acquired from the radiographic image capturing apparatus 10. It may be.

  Further, a plurality of cradle 230 is connected to a network, the charging state of the radiographic imaging device 10 connected to each cradle 230 is collected via the network, and the location of the radiographic imaging device 10 in a usable charging state is located. It can also be configured so that it can be confirmed.

  In the above description, radiographic images were taken at disaster sites and home nursing sites. However, the present embodiment is not limited to the radiography at these sites. It is also possible to apply to imaging of a subject in diagnosis or to imaging of a patient during a round-trip in the medical institution 40. Or this embodiment is not limited to imaging | photography of such a medical-related radiographic image, Of course, for example, it is applicable also to imaging | photography of the radiographic image in various nondestructive inspections.

  Next, modified examples (first to tenth modified examples) of the present embodiment will be described with reference to FIGS.

  In these modified examples, the same components as those in FIGS. 1 to 99 are described with the same reference numerals, and detailed description thereof is omitted. In FIGS. 100 to 109, the network 36 and the medical institution 40 are not shown.

  As shown in FIG. 100, the radiographic image capturing apparatus 10A and the radiographic image capturing system 11A according to the first modified example transmit and receive signals between the portable information terminal 34 and the radiation source main body 16 and the cassette main body 22. It differs from the embodiment of FIGS. 1 to 99 in that it is performed by wired communication.

  That is, since the portable information terminal 34 and the radiation source body 16 and the cassette body 22 are electrically connected via the USB cables 24 and 26, the radiation source body is connected from the battery 220 of the portable information terminal 34. The battery 134 of the unit 16 and the battery 166 of the cassette body 22 can be reliably charged, and signals can be transmitted and received reliably. In this way, power supply by wire using the USB cables 24 and 26 and transmission / reception of signals (signal transmission) become possible, so that the portable information terminal 34 can connect to the radiation source main body 16 and the cassette main body 22. Transmission of a synchronous control signal and imaging conditions, and transmission of a radiographic image from the cassette body 22 to the portable information terminal 34 can be reliably performed.

  As shown in FIG. 101, the radiographic image capturing apparatus 10B and the radiographic image capturing system 11B according to the second modification are configured such that the web camera 330 is accommodated in the radiation source main body 16 and the web camera 30 is not provided. , Different from the embodiment of FIGS.

  In this case, the web camera 330 also captures a face image including the pupil of the subject 18 before capturing the radiographic image. That is, the web camera 330 also has the function of the web camera 30 in the embodiment of FIGS.

  Thus, since the second modified example is the same as the embodiment of FIGS. 1 to 100 except that the web camera 30 is not provided, each effect of FIGS. 1 to 100 other than the point where the web camera 30 exists is provided. Of course, it is easily obtained.

  As shown in FIG. 102, the radiographic image capturing apparatus 10C and the radiographic image capturing system 11C according to the third modification are illustrated in that the web camera 30 is accommodated in the portable information terminal 34 and the web camera 330 is not provided. 1 to FIG. 100 are different from the embodiment.

  Since the third modified example is the same as the embodiment of FIGS. 1 to 100 except that the web camera 330 is not provided, each effect of FIGS. 1 to 100 other than the point where the web camera 330 exists can be easily obtained. Of course.

  In the radiographic image capturing apparatus 10D and the radiographic image capturing system 11D according to the fourth modification, as shown in FIG. 103, the web camera 330 and the radiation source main body 16 are connected via the USB cable 240 (integrated configuration). This is different from the second modified example (see FIG. 101).

  The fourth modification is the same as the second modification except that the web camera 330 is connected to the radiation source main body 16 via the USB cable 240. Therefore, the same effect as the second modification is obtained. It is done. Further, since the web camera 330 can be disposed in a desired position independently within the range of the length of the USB cable 240, the web camera 330 is built in the radiation source main body 16. Compared to the above, the degree of freedom in positioning the webcam 330 can be increased. Since the web camera 330 includes the communication unit 260, the communication unit 260 communicates with the communication unit 104 of the medical institution 40 via the network 36 (see FIG. 1). Transmission and reception of signals such as images may be performed directly.

  As shown in FIG. 104, in the radiographic image capturing apparatus 10E and the radiographic image capturing system 11E according to the fifth modification, the web camera 30 and the portable information terminal 34 are connected (integratedly configured) via the USB cable 240. This is different from the third modified example (see FIG. 102).

  The fifth modified example is the same as the third modified example except that the web camera 30 is connected to the portable information terminal 34 via the USB cable 240. Therefore, the same effect as the third modified example can be obtained. . Further, since the web camera 30 can be placed in a desired position independently within the length of the USB cable 240, the mobile information terminal 34 has a configuration in which the web camera 30 is built-in. In comparison, the degree of freedom in positioning the webcam 30 can be increased. Since the web camera 30 includes the communication unit 260, the communication unit 260 communicates with the communication unit 104 of the medical institution 40 via the network 36 (see FIG. 1). Transmission and reception of signals such as images may be performed directly.

  As shown in FIG. 105, in the radiographic imaging apparatus 10F and the radiographic imaging system 11F according to the sixth modification, the web camera 30 (330), the portable information terminal 34, and the radiation source main body 16 are separated. In that it differs from the embodiment of FIGS.

  In this case, since the portable information terminal 34, the radiation source main body 16, the cassette main body 22, and the web camera 30 (330) are connected to each other via the same link, the communication unit 104 (the medical institution 40 ( Transmission / reception of signals such as camera images and radiographic images to / from the communication unit 136, 170, 218 (see FIG. 12) and the communication unit 260 of the web camera 30 (330) is performed. This may be done via one communication unit. For example, the web camera 30 (330) directly transmits a camera image from the communication unit 260 to the medical institution 40 via the network 36 (see FIG. 1) or from the communication unit 260 to the communication unit of the radiation source body unit 16. 136, the camera image may be indirectly transmitted to the medical institution 40 via the communication unit 170 of the cassette body 22 or the communication unit 218 of the portable information terminal 34. Even in this case, the doctor 38 can see the camera image of the web camera 30 (330).

  Further, since the web camera 30 (330) is arranged in a self-supporting state, the web camera 30 (330) can be arranged at a desired position. Therefore, the web camera 30 (330) can be freely positioned. The degree can be further increased.

  The sixth modification is the same as that shown in FIGS. 1 to 104 except that signals are transmitted and received by wireless communication between the portable information terminal 34, the web camera 30 (330), the radiation source main body 16 and the cassette main body 22. Since it is the same as that of embodiment, each effect of FIGS. 1-104 other than the point by which signal transmission / reception is performed by the said wireless communication can also be acquired.

  As illustrated in FIG. 106, the radiographic image capturing apparatus 10 </ b> G and the radiographic image capturing system 11 </ b> G according to the seventh modification are further provided with a web camera 246 for capturing the operator 32 when operating the portable information terminal 34. This is different from the embodiment of FIGS.

  In this case, the portable information terminal 34 transmits the camera image (image of the operator 32) of the web camera 246 to the medical institution 40 (see FIG. 1) by wireless communication via the network 36. While looking at an image-related instruction while viewing the image of the doctor 38 displayed on the unit 64, the doctor 38 gives an instruction to the operator 32 while viewing the image of the operator 32 displayed on the display unit 112. Therefore, the operator 32 can feel close to the doctor 38 in the remote medical institution 40, while the doctor 38 can feel close to the operator 32 in the local area, so that the preparation for photographing can be performed with peace of mind.

  In FIG. 107, the web camera 30 (330) is built in the lid 66, but of course, it may be built in the radiation source main body 16. The eighth modification is the same as the embodiment of FIGS. 1 to 105 except that the radiation source main body 16 and the portable information terminal 34 are integrated. Of course, the effects of FIGS. 1 to 105 other than the integration of the information terminal 34 can be easily obtained.

  As shown in FIG. 108, in the radiographic imaging apparatus 10I and the radiographic imaging system 11I according to the ninth modification, the radiation source 14 is a conventional thermoelectron emission type radiation source, and the filament of the radiation source 14 is energized. The embodiment is different from the embodiment shown in FIGS.

  In this case, the radiation source 14 and the communication unit 136 are housed in a housing 250 attached to the upper end of the leg 248, and the USB cable 24 electrically connects the housing 250 and the high voltage power supply 252. It is connected to the. Further, the high voltage power supply 252 and the portable information terminal 34 are electrically connected by a USB cable 254 having connectors 256 and 258. Therefore, the portable information terminal 34 can output the radiation 12 from the radiation source 14 by controlling the high voltage power supply 252.

  In the ninth modification, since the conventional thermoelectron emission type radiation source 14 is used, the entire apparatus is increased in size and the number of parts is increased. However, even in this case, the thermoelectron emission type radiation source 14 is used. Of course, the effects of FIGS. 1 to 107 other than the above are obtained.

  As shown in FIG. 108, a communication unit 262 is mounted on the high voltage power supply 252. In this case, the communication unit 262 may transmit and receive signals such as radiation images and camera images to and from the communication unit 104 of the medical institution 40 via the network 36 (see FIG. 1).

  As shown in FIG. 109, the radiographic image capturing apparatus 10J and the radiographic image capturing system 11J according to the tenth modification include a console 106 and a radiographic image capturing apparatus 10J in an examination car 300 (standby place) where a doctor 38 waits. A plurality of accommodated attach cases 98 are mounted, and the operator 32 (see FIG. 1) takes at least one attach case 98 from the examination car 300 and transports it to the site, which is different from the case of FIGS. Different. Therefore, the inside of the examination car 300 on which the doctor 38 waits is a waiting place where the subject 18 cannot be seen directly.

  Even in this case, wireless transmission / reception of signals between the radiographic imaging apparatus 10J transported to the site and the communication unit 104 in the examination car 300, for example, radio transmission from the radiographic imaging apparatus 10J to the communication unit 104 is performed. Since it is possible to transmit a camera image or a radiographic image, the same effects as in FIGS. 1 to 108 can be obtained. Note that FIG. 109 illustrates a case where wireless signal transmission / reception is directly performed between the radiographic imaging apparatus 10J and the communication unit 104, but wireless communication via the network 36 (see FIG. 1) is performed. Of course, the same effect can be obtained.

  In the present embodiment, as shown in FIGS. 110A and 110B, a recess 324 is formed at a location opposite to the output location of the radiation 12 in the radiation source main body 16, and a retractable handle 320 is formed in the recess 324. May be provided. A touch sensor 322 having the same function as the touch sensor 312 described above may be provided on the handle 320.

  Here, in a state where the operator 32 does not have the radiation source main body 16, the handle 320 is housed in the recess 324 as shown in FIG. 110A. On the other hand, when the operator 32 rotates the handle 320 around the base end side of the handle 320, the handle 320 is pulled out from the recess 324, so that the operator 32 holds the handle 320. Is possible. Even in this case, the same effects as those obtained by the handle 310 and the touch sensor 312 can be obtained.

  Further, when the handle 320 is stored (for example, when the radiation source body 16 as shown in FIG. 7 is moved), the electrode of the touch sensor 312 and the hand of the operator 32 do not come into contact with each other. It can be avoided that the radiation 12 is erroneously output from the radiation source 14 in a state where the unit 16 is activated.

  Furthermore, in the present embodiment, transmission / reception of signals by wireless communication and / or wired communication has been described. However, when the subject 18 is in contact with the radiation source main body 16 and the cassette main body 22 and the SID is set short. Alternatively, transmission / reception of signals between the radiation source main body 16 and the cassette main body 22 (for example, transmission / reception of synchronization control signals) may be human body communication via the subject 18. Further, when the operator 32 is in contact with both the radiation source main body 16 and the portable information terminal 34, transmission / reception of signals between the radiation source main body 16 and the portable information terminal 34 is performed. It may be performed by human body communication via the network.
