Description

  The present invention relates to a radiographic imaging system, and more particularly to a radiographic imaging system including a radiographing room for radiographic imaging and a console for image processing image data obtained by radiographic imaging.

  A so-called direct type radiographic imaging device that generates electric charges by a detection element in accordance with the dose of irradiated radiation such as X-rays and converts it into an electrical signal, or other radiation such as visible light with a scintillator or the like. Various so-called indirect radiographic imaging devices have been developed that convert charges to electromagnetic waves after being converted into electrical signals by generating electric charges with photoelectric conversion elements such as photodiodes in accordance with the energy of the converted and irradiated electromagnetic waves. Yes. In the present invention, the detection element in the direct type radiographic imaging apparatus and the photoelectric conversion element in the indirect type radiographic imaging apparatus are collectively referred to as a radiation detection element.

  This type of radiographic imaging device is known as an FPD (Flat Panel Detector), and conventionally formed integrally with a support base (or a bucky device) (for example, see Patent Documents 1 and 2). A portable radiographic imaging apparatus in which a radiation detection element and the like are housed in a housing has been developed and put into practical use (see, for example, Patent Documents 3 and 4).

  By the way, radiographic imaging is performed, and whether or not the subject is correctly captured by the radiographic imaging device, that is, whether or not the subject is captured on the radiographic image and the subject is captured at an appropriate position on the radiographic image. The operator, such as a radiographer, determines whether or not the image is actually taken.

  At that time, it is conceivable that the radiation image capturing apparatus is provided with a display unit such as a monitor, and the captured image is displayed on the display unit for confirmation. In particular, the radiation image capturing apparatus is portable. When the radiographic image capturing apparatus is used while being loaded into a bucky device, the monitor is often not visible when the radiographic image capturing device is loaded into the bucky device, and the usability is not necessarily good.

  Further, the image data captured by the radiation image capturing apparatus is often image-processed by a console outside a capturing room configured by a computer or the like, and a final diagnostic radiation image is created. In such a case, it is very inconvenient for the operator if the operator goes out of the radiographing room and goes to the console after confirmation after radiographic imaging.

  Therefore, in Patent Document 1, although it is a case of a radiographic imaging apparatus integrated with a support base, a display unit is provided on a support base for standing imaging or supine imaging and transmitted from the radiographic imaging apparatus. There is described a radiographic imaging system configured to display the image data displayed on the display units so that an operator can check in the imaging room.

Japanese Patent No. 3890163 JP-A-9-73144 JP 2006-058124 A JP-A-6-342099

  However, in the case of a radiographic imaging system described in Patent Document 1, when a radiographic imaging apparatus integrated with a support base is newly installed in the imaging room, a radiographic imaging apparatus with a display unit is installed. For example, if a person concerned with a facility such as a hospital does not feel much resistance, for example, if a device such as a bucky device that has no electrical wiring is already installed in the photographic room, such a device is newly added to such a device. Wiring the cable and installing the display unit has a problem of cost and the like, and feels resistance.

  In addition, unlike the case of the radiographic image capturing apparatus integrated with the support base, when the radiographic image capturing apparatus is portable, for example, one radiographic image capturing apparatus is placed in a standing position with a bucky apparatus for standing position imaging. It can be used in both of the shooting bucky devices, and it can be used in a single state, for example, between the bed and the patient's body without being loaded in those bucky devices. is there.

  However, on the other hand, on the contrary, it is precisely managed in what state the portable radiographic imaging device is used in the imaging room or whether the portable radiographic imaging device exists in the target imaging room in the first place. Otherwise, for example, although the intended patient was photographed with a radiographic imaging device different from the radiographic imaging device intended by the operator, it was mistaken for being taken with the intended radiographic imaging device. There is a possibility that inconvenience may occur that the image data of another person is read from the radiographic image capturing apparatus and used as the image data of the target patient.

  Further, for example, when there are a plurality of radiographing rooms, the radiographic imaging apparatus is moved to the first radiographing room on the console side even though the portable radiographic imaging apparatus is carried from one radiographing room to another radiographing room. If processing is carried out as if there is, there is a possibility that the same inconvenience may occur.

  In this way, when using a portable radiographic imaging device, one radiographic imaging device can be shared by a standing-up imaging device or a standing-up imaging device, or a single device. Although there are various merits such as being able to be used in a state, there is a concern that a problem in system control such as incorrect correspondence between the patient and the radiographic image taken may occur.

  The present invention has been made in view of the above points, is easy to use for operators such as radiographers, and moreover manages the portable radiographic imaging apparatus to avoid occurrence of problems in system control. It is an object of the present invention to provide a radiographic imaging system that can be appropriately operated.

In order to solve the above-described problem, the radiographic imaging system of the present invention includes:
At least one imaging room for irradiating the subject with radiation and taking radiographic images;
A portable radiographic imaging device that obtains image data by radiographic imaging performed in the imaging room, and creates thinning data in which the image data is thinned out at a predetermined ratio based on the image data;
A console that performs image processing on the image data transmitted from the portable radiographic imaging device to obtain a final diagnostic radiographic image;
A management device integrated with or separate from the console for managing whether or not the portable radiographic imaging device is present in the imaging room;
A registration unit provided in the radiographing room, reading the identification information of the portable radiographic imaging device brought into the radiographing room and notifying the console and the management device; and a registration unit comprising a display unit;
With
When the thinning data is transmitted from the portable radiographic imaging device, the console transfers the thinning data to the registration unit,
The registration means displays the thinned data transferred from the console on the display means,
When the identification information of the portable radiographic imaging device is notified from the registration unit, the management device stores the identification information of the radiographic room and the identification information of the portable radiographic imaging device in association with each other. It is characterized by.

  According to the radiographic imaging system of the system of the present invention, after radiographic imaging, the thinning data for preview is automatically transmitted from the portable radiographic imaging device to the console, and the thinning data transferred from the console is automatically Are displayed on the display means of the registration means. Therefore, it is possible to operate the X-ray irradiation switch in the front room of the radiographing room, return from the front room to the radiography room for the next radiography, and an operator such as a radiographer in the radiography room can see the preview image on the spot Thus, since it is possible to determine whether or not re-shooting is necessary, the next shooting can be quickly started. Therefore, it becomes very convenient for the operator. In addition, when the X-ray irradiation switch is operated, it takes a very short time to leave the patient alone in the imaging room, and the patient can be sufficiently cared for.

  When the portable radiographic imaging device is registered by the registration unit of the radiographing room, the identification information is notified to the management device, and the management device takes the identification information of the portable radiographic imaging device and the imaging The identification information of the room is associated with and stored in the storage means. Therefore, the management apparatus accurately manages in which imaging room the target portable radiographic imaging apparatus exists, or in which imaging room R the portable radiographic imaging apparatus does not exist. Is possible.

  In addition, it becomes possible to reliably obtain the image data of the target patient from the target portable radiographic image capturing apparatus, and it is possible to appropriately avoid the occurrence of problems in system control and to appropriately Operation becomes possible.

Moreover, in this embodiment, the buffer material 36 for preventing that they collide between the sensor panel SP and the side surface of the housing | casing 2 is provided.

  The scintillator 3 is attached to a detection unit P, which will be described later, of the substrate 4. In the present embodiment, the scintillator 3 is, for example, a phosphor whose main component is converted into an electromagnetic wave having a wavelength of 300 to 800 nm when receiving radiation, that is, an electromagnetic wave centered on visible light and output. .

  In the present embodiment, the substrate 4 is made of a glass substrate. As shown in FIG. 8, a plurality of scanning lines 5 and a plurality of signal lines are provided on a surface 4 a of the substrate 4 facing the scintillator 3. 6 are arranged so as to cross each other. In each small region r defined by the plurality of scanning lines 5 and the plurality of signal lines 6 on the surface 4 a of the substrate 4, radiation detection elements 7 are respectively provided.

  Thus, the entire region r in which a plurality of radiation detection elements 7 arranged in a two-dimensional manner are provided in each small region r partitioned by the scanning line 5 and the signal line 6, that is, shown by a one-dot chain line in FIG. The region is a detection unit P.

  In the present embodiment, a photodiode is used as the radiation detection element 7, but other than this, for example, a phototransistor or the like can also be used. As shown in FIG. 9 which is an enlarged view of FIG. 8, each radiation detection element 7 is connected to the source electrode 8s of the TFT 8 which is a switch means. The drain electrode 8 d of the TFT 8 is connected to the signal line 6.

  The TFT 8 is turned on when a turn-on voltage is applied to the gate electrode 8g via the scanning line 5 from the scanning driving means 15 described later, and is accumulated in the radiation detection element 7 via the source electrode 8s and the drain electrode 8d. The charged electric charge is discharged to the signal line 6. The TFT 8 is turned off when an off voltage is applied to the gate electrode 8g via the connected scanning line 5, and the emission of the charge from the radiation detecting element 7 to the signal line 6 is stopped, and the radiation detecting element The electric charge is held in 7.

  In the present embodiment, as shown in FIG. 9, the bias lines 9 are respectively connected to the plurality of radiation detection elements 7 arranged in a row, and as shown in FIG. 8, each bias line 9 is connected to the substrate 4. Are bound to one connection 10 at a position outside the detection portion P.

  In addition, each scanning line 5, each signal line 6, and connection line 10 of the bias line 9 are connected to input / output terminals (also referred to as pads) 11 provided near the edge of the substrate 4. As shown in FIG. 10, a COF (Chip On Film) 12 in which a chip such as an IC 12a is incorporated in each input / output terminal 11 is an anisotropic conductive adhesive film (Anisotropic Conductive Film) or anisotropic conductive paste (Anisotropic paste). It is connected via an anisotropic conductive adhesive material 13 such as Conductive Paste).

  The COF 12 is routed to the back surface 4b side of the substrate 4 and connected to the PCB substrate 33 described above on the back surface 4b side. Thus, the board | substrate 4 part of sensor panel SP of the radiographic imaging apparatus 1 is formed. In FIG. 10, illustration of the electronic component 32 and the like is omitted.

  Here, the circuit configuration of the radiation image capturing apparatus 1 will be described with reference to FIG.

  A bias line 9 is connected to one electrode of each radiation detection element 7, and each bias line 9 is bound to a connection 10 and connected to a bias power supply 14. The bias power supply 14 applies a bias voltage (reverse bias voltage in this embodiment) to the electrode of each radiation detection element 7 via the connection 10 and each bias line 9.

  The other electrode of each radiation detection element 7 is connected to a source electrode 8s (denoted as S in FIG. 11) of the TFT 8, and a gate electrode 8g of each TFT 8 (denoted as G in FIG. 11). Are connected to the lines L1 to Lx of the scanning line 5 extending from the gate driver 15b of the scanning driving means 15, respectively. Further, the drain electrode 8d (denoted as D in FIG. 11) of each TFT 8 is connected to each signal line 6.

  The scanning drive unit 15 includes a power supply circuit 15a that supplies an on voltage and an off voltage to the gate driver 15b, and a gate driver 15b that switches a voltage applied to each of the lines L1 to Lx of the scanning line 5 between the on voltage and the off voltage. It has. As described above, the gate driver 15b switches the voltage applied to the gate electrode 8g of the TFT 8 via the lines L1 to Lx of the scanning line 5 between the on-voltage and the off-voltage, It is designed to control the off state.

  Each signal line 6 is connected to each readout circuit 17 formed in the readout IC 16. The readout circuit 17 includes an amplifier circuit 18, a correlated double sampling circuit 19, an analog multiplexer 21, and an A / D converter 20.

  For example, in radiographic imaging, radiation is applied to the radiographic imaging apparatus 1 through a subject, and the scintillator 3 converts the radiation into electromagnetic waves of other wavelengths and irradiates the radiation detection element 7 directly therebelow. Then, electric charges (electric signals) are generated according to the dose of radiation (the amount of electromagnetic waves) irradiated by the radiation detection element 7.

  In the process of reading charges from each radiation detection element 7, the TFT 8 in which an on-voltage is applied to the gate electrode 8 g from the gate driver 15 b of the scanning drive unit 15 through the lines L 1 to Lx of the scanning line 5 is turned on. Electric charges are emitted from the radiation detection element 7 to the signal line 6.

  Then, a voltage value is output from the amplifier circuit 18 in accordance with the amount of charge emitted from the radiation detection element 7, and is correlated double-sampled by the correlated double sampling circuit 19, and the analog value image data D is sent to the multiplexer 21. Is output. The image data D sequentially output from the multiplexer 21 is sequentially converted to digital image data D by the A / D converter 20, output to the storage means 23 and sequentially stored.

  The control means 22 includes a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), a computer having an input / output interface connected to the bus, an FPGA (Field Programmable Gate Array), and the like. ing. It may be configured by a dedicated control circuit.

  The control means 22 controls the operation of each member of the radiographic image capturing apparatus 1. Further, the reset process of each radiation detection element 7, the readout process of charges from each radiation detection element 7, and the same process as the readout process after leaving the radiation imaging apparatus 1 in a state in which no radiation is irradiated to calculate the offset correction value. Each process such as a dark reading process for reading out the dark charge accumulated in each radiation detecting element 7 is performed.

  The control means 22 is connected to a storage means 23 constituted by a DRAM (Dynamic RAM) or the like, and a battery 24 that supplies power to each functional unit of the radiographic image capturing apparatus 1. Further, the above-described antenna device 41 is connected to the control means 22, and although not shown in FIG. 11, the above-described power switch 37, selection switch 38, connector 39, etc. (see FIG. 5) are connected. Has been.

  When the selection switch 38 is pressed by an operator such as a radiologist, the control means 22 transmits a selection signal indicating that it has been selected to the console C via the antenna device 41. As will be described later, when the radiographic imaging apparatus 1 is inserted into the cradle 55 and the connector 39 is connected to the connector 55 a of the cradle 55, the control means 22 identifies the radiographic imaging apparatus 1 identification information. The information such as the cassette ID is notified to the cradle 55.

  Further, when the connector 39 is connected to a connector 51c of a notification means 51b (see FIG. 12) described later, the control means 22 acquires information such as a Bucky ID that is identification information of the bucky device 51 described later from the notification means 51b. Both the Bucky ID and the cassette ID of the radiation image capturing apparatus 1 are transmitted to the console C.

  Further, when radiographic imaging is performed, the control unit 22 performs a readout process of reading out charges (image data D) from each radiation detection element 7 as described above. On the basis of the image data D stored in the image data, the image data D is thinned out at a predetermined rate to generate the thinned data Dt for preview.

  When the radiographic image capturing is completed and the image data D is read from each radiation detection element 7 and stored in the storage unit 23, the thinned data Dt is immediately created, and as soon as the thinned data Dt is created, the antenna is immediately created. The thinned data Dt is transmitted to the console C via the device 41. This thinning data Dt is transmitted every time radiographic images are taken.

  The thinned data Dt is, for example, image data D for one pixel every 3 × 3 pixels or 4 × 4 pixels when each image data D is arranged corresponding to each radiation detecting element 7 arranged in a two-dimensional form. Or the image data D from each radiation detection element 7 connected to each line L1, L4, L7,... Of the scanning line 5, respectively. The image data D from each radiation detection element 7 connected to each line Ln at predetermined intervals may be extracted and created.

  In this embodiment, the control means 22 transmits the thinned data Dt to the console C, and then transmits the corresponding image data D that is the basis for creating the thinned data Dt to the console C. Yes.

  In addition, when the radiographic imaging is completed alone or in series, the control unit 22 performs so-called dark reading processing in order to obtain data for offset correction among the image processing for the image data D obtained by radiographic imaging. Is supposed to do.

  In the dark reading process, each TFT 8 of the radiographic image capturing apparatus 1 is turned off and left for a predetermined time in a state where the radiation image capturing apparatus 1 is not irradiated with radiation. The dark charges and the like accumulated therein are read out as a so-called dark read value d and stored in the storage means 23.

  The control means 22 transmits the dark read value d together with the transmission of the image data D to the console C when there is an operation by the operator or when there is a transmission request from the console C. It has become.

  By the way, as described above, in the present embodiment, it is assumed that the radiographic image capturing apparatus 1 is loaded into a screen / film cassette or a CR cassette bucky device 51. The radiographic image capturing apparatus 1 is a CR cassette. It is formed with dimensions such as 14 inches × 17 inches (half-cut size) conforming to JIS standard sizes (ie, JIS standard sizes in conventional screen film cassettes, corresponding international standards are IEC 60406). Further, the thickness in the radiation incident direction is formed to be within a range of 15 mm + 1 mm to 15 mm-2 mm.

  However, when a screen / film cassette or a CR cassette cassette is not used, it is not necessary to form the radiographic imaging apparatus 1 with the above dimensions, and the radiographic imaging apparatus 1 is formed in an arbitrary size and shape. be able to. In that case, the Bucky device 51 needs to be provided with a new Bucky device formed in accordance with the shape of the radiation image capturing device 1 so that the radiation image capturing device 1 can be loaded.

  Next, the configuration of the imaging room R in the radiographic image capturing system 100 shown in FIG. 1 and the like will be described in detail.

  The imaging room R is a room in which radiation imaging is performed by irradiating a subject (part of the patient's imaging target) that is a part of the patient's body to irradiate the subject with radiation as shown in FIG. The radiation generating device 52 and the like of the radiation irradiating device are arranged so that the radiation is prevented from leaking out of the photographing room, the so-called photographing room Ra, and the radiation irradiation device console 56 and the like operated by an operator such as a radiologist. Is disposed in the front chamber (also referred to as an operation chamber or the like) Rb.

  Note that FIG. 12 shows a case where one console C is connected to one shooting room R. As described above, this is the case when the configuration of the shooting room R is described. The case where R and the console C are connected to 1: 1 is illustrated together, and the present invention is not limited to this case.

  In the present embodiment, the radiographing room Ra is provided with a bucky device 51 that can be loaded with the above-described radiographic imaging device 1 and a radiation generation device 52 that includes an X-ray tube (not shown) that generates radiation to irradiate a subject. ing.

  As described above, the bucky device 51 is an existing bucky device formed so as to be used by loading a CR cassette into the cassette holding portion (cassette holder) 51a in this embodiment. The apparatus 1 can also be used by being loaded into the cassette holding part 51a.

  Further, the existing Bucky device 51 includes a non-volatile memory that stores information such as a Bucky ID that is identification information of the Bucky device 51 to the radiographic imaging device 1, a non-volatile memory that stores power source and Bucky ID information, and a communication control CPU (Both are not shown in the figure.) And the like are newly provided. The notification means 51b may be provided so as to be attached to the bucky device 51, or may be provided in the vicinity of the bucky device 51.

  When the connector 51c of the notification unit 51b is connected to the connector 39 of the radiographic image capturing apparatus 1, the notification unit 51b notifies the radiographic image capturing apparatus 1 of information such as the bucky ID of the bucky unit 51 corresponding to the notification unit 51b. It is supposed to be.

  Then, as described above, before the radiographic imaging device 1 is loaded into the bucky device 51, the connector 51c of the notification unit 51b is connected to the connector 39 as shown in FIG. When information such as a bucky ID which is identification information is notified, the control means 22 of the radiographic image capturing apparatus 1 transmits both the bucky ID and the cassette ID of the radiographic image capturing apparatus 1 to the console C. ing.

  The connector 51c of the notification means 51b is removed when the radiographic imaging device 1 is loaded into the bucky device 51, but the radiographic imaging device 1 is loaded into the bucky device 51 while the connector 51c remains connected to the connector 39. If possible, it may be configured to load while connected.

  Further, when the connector 39 of the radiographic imaging device 1 is connected to the connector 51c of the notification unit 51c, the radiation generation device 52A related to the bucky device associated with the notification unit 51c has not been activated yet. The radiation generator 52A is automatically activated at the stage of connection, and the position, radiation irradiation direction, and the like are adjusted in accordance with the bucky device 51.

  As shown in FIG. 12, in the present embodiment, in the photographing room Ra, a bucky device 51 </ b> A for standing position photography and a bucky device 51 </ b> B for standing position photography are installed as the bucky device 51. However, for example, the present invention is also applied to the case where only one Bucky device 51 is provided in the photographing room Ra, such as only the Standing photographing Bucky device 51A.

  In the present embodiment, one of the radiation generators 52A among the radiation generators 52A changes the position and the irradiation direction of the irradiation line, thereby changing the standing device shooting device 51A and the lying device shooting device. Radiation imaging can be performed by irradiating the radiation imaging apparatus 1 loaded in the apparatus 51B with radiation.

  Further, in the present embodiment, a portable radiation generation device 52B that is not associated with the standing-up photographing or the buckling device 51A, 51B is also provided. The portable radiation generator 52B can be carried anywhere in the photographing room Ra and can irradiate radiation in an arbitrary direction.

  The radiographic imaging device 1 is applied to a patient's body part as a subject in a single state (that is, not loaded in the bucky device 51), or a bucky device 51B for lying position photography or a bed and a patient's body not shown. The radiation can be emitted from an appropriate distance and direction using the portable radiation generator 52B.

  The imaging room Ra is shielded with lead or the like so that the radiation irradiated in the imaging room Ra does not leak outside. Therefore, even if information such as image data D is transmitted / received from the radiation image capturing apparatus 1 via the antenna apparatus 41 in the image capturing room Ra, it cannot be transmitted / received as it is. Therefore, in this embodiment, when the radiographic imaging apparatus 1 and the console C perform wireless communication, a base station (wireless access point) 54 including a wireless antenna 53 that relays these communication is provided.

  In addition, in FIG. 12, although each Bucky apparatus 51 and the base station 54 are represented as being connected by a cable or the like, this means that they are connected by a wired method such as a cable or the like. Instead, it is not necessary to newly provide the imaging room Rni when there is no cable or the like connecting them originally.

  When the base station 54 relays communication, the base station 54 is configured to add information such as its own base station ID to information to be relayed. By looking at the base station ID of the base station 54 added to the information, It is possible to determine from which shooting room R (R1 to R4) the information is transmitted.

  That is, since one base station 54 is provided in each photographing room R, when the base station ID of the base station 54 is transmitted, the side that received the base station 54 is the photographing room in which the base station 54 is installed. It can be determined that the information is transmitted from R, and the base station ID of the base station 54 corresponds to the identification information of the photographing room R.

  A cradle 55 is connected to the base station 54. After transmitting the thinning data Dt from the radiographic imaging apparatus 1 to the console C as described later, the base station 54 transfers the thinning data Dt to the cradle 55 when the thinning data Dt is transferred from the console C. It is like that.

  The cradle 55 is normally used for storing or charging the radiation image capturing apparatus 1 or the like, but in the present invention, the cradle 55 is used for registration of the inserted radiation image capturing apparatus 1. It has become.

  Specifically, in this embodiment, as shown in FIG. 14, the radiographic imaging device 1 is brought into the imaging room Ra and inserted into the cradle 55, and the connector 39 and the cradle 55 of the radiographic imaging device 1 are inserted. When the connector 55a provided in the mouth is connected, the cradle 55 as registration means reads the cassette ID that is the identification information of the radiographic imaging device 1, and the corresponding console C or management device S (see FIG. 1) and so on.

  Further, as illustrated in FIG. 15, the cradle 55 includes display means 55 b made of a CRT (Cathode Ray Tube), an LCD (Liquid Crystal Display), or the like. In addition, when the thinned data Dt is transferred from the console C via the base station 54, the cradle 55 displays it on the display means 55b as a preview image.

  14 and 15 show the cradle 55 provided with two insertion ports for inserting the radiographic imaging apparatus 1, but the number of insertion ports may be one, or three or more. Also good. Further, the radiographic imaging device 1 can be charged by the cradle 55 or the like.

  The cradle 55 may be installed in either the imaging room Ra or the front room Rb. When the cradle 55 is installed in the imaging room Ra, a position where the radiation irradiated from the radiation generator 52 does not reach, for example, each corner. It is installed in the department. Further, it is possible to provide the cradle 55 with an input means by providing a numeric keypad or the like, or using the display means 55b as a touch panel.

  As shown in FIG. 12, the front room Rb is provided with an operation console 57 for controlling radiation irradiation, including a switch means 56 for instructing the radiation generator 52 to start radiation irradiation. Yes. Although not shown in FIG. 12, display means such as a monitor for displaying a list of photographing order information transmitted from the console C as described later is provided in the console 57 and the photographing room Ra. It is also possible to configure.

  The console C (see FIG. 1 and the like) is configured by a computer or the like in which a CPU, a ROM, a RAM, an input / output interface and the like (not shown) are connected to a bus. A predetermined program is stored in the ROM, and the console C reads out a necessary program, expands it in a work area of the RAM, and executes various processes according to the program.

  The console C is provided with a display section Ca made up of a CRT, LCD, or the like, and other input means such as a keyboard or a mouse are connected. The console C is connected to a storage means Cb composed of a hard disk or the like. The storage means Cb includes a cassette ID of the radiation image capturing apparatus 1 that can be used for radiation image capturing in each imaging room R, and A table in which information such as scintillator type information, size information, and resolution is associated is stored in advance.

  The storage means Cb stores in advance a table in which a shooting room ID, which is identification information of the shooting room R, and a base station ID of the base station 54 provided in the shooting room R are associated with each other. When information such as the image data D is transmitted via the base station 54, the console C refers to the table, and the imaging room in the imaging room R corresponding to the base station ID of the base station 54 added to the information. An ID is determined, and it is determined that the information is information transmitted from the imaging room R from which the information has been determined.

  As shown in FIG. 1 and the like, each photographing room R (R1 to R4) is connected to each console C (C1 to C3) by a predetermined connection method (in the case of FIG. 1), or a network N (In the case of FIG. 2). That is, in each console C (C1 to C3), each base station 54 and each console 57 (not shown in FIG. 1 and FIG. 2; see FIG. 12) of each photographing room R (R1 to R4) are predetermined. They are connected in a connection manner or via the network N.

  As will be described later, in the console C, radiographing order information representing the contents of radiographic imaging performed in a predetermined radiographing room R is managed for each radiographing room, and the radiographing order information is managed from the console C to the console 57 of the radiographing room R. The console C and the imaging room R are associated with each other so that imaging conditions such as tube current and tube voltage at the time of each imaging can be automatically set in the radiation generator 52.

  Prior to radiographic imaging, radiographic imaging imaging order information generated in advance from the HIS and RIS connected to the network N is transmitted to each console C in a list format. The operator selects order information for photographing in each photographing room from this list on any console C.

  In the present embodiment, as illustrated in FIG. 16, the imaging order information includes “patient ID” P2, “patient name” P3, “sex” P4, “age” P5 as patient information, and “imaging” as imaging conditions. It includes a “part” P6 and an “imaging direction” P7. Then, “shooting order ID” P1 is automatically assigned to each shooting order information in the order in which the shooting orders are received.

  The patient information and the imaging conditions to be written in the imaging order information are not limited to those described above, and include, for example, information such as the patient's date of birth, the number of medical examinations, the radiation dose, and whether the patient is fat or thin. It can also be configured as described above, and can be set as appropriate.

  When radiographing order information of radiographic imaging is acquired from the HIS or RIS, a list of radiographing order information in a list format is displayed on the display unit Ca of the console C as a selection screen H1, as shown in FIG. It has become.

  In the present embodiment, the selection screen H1 is provided with a shooting order information display field h11 for displaying a list of each shooting order information, and on the left side of the shooting order information display field h11 is a target shooting room R. A selection button h12 for selecting shooting order information scheduled to be shot at is provided corresponding to each shooting order information. In addition, a determination button h13 and a return button h14 are provided below the shooting order information display field h11.

  The operator clicks the selection button h12 to select one or more pieces of shooting order information scheduled to be shot in the target shooting room R, and clicks the decision button h13. And although illustration is abbreviate | omitted, the target imaging | photography room R is selected on the screen which selects imaging | photography room R1-R4 displayed after clicking the determination button h13. When each shooting order information and the target shooting room R are selected, a list of each selected shooting order information is associated with the shooting room ID of the target shooting room R and stored in the storage unit Cb.

  At the same time, a list of each shooting order information selected from the console C operated by the operator is transmitted to the console 57 of the target shooting room R or the like. As described above, the list of imaging order information is transmitted from the console C to the target imaging room R, and as described above, the console C and the target imaging room R are associated with each other.

  Note that before creating the list of shooting order information, it is also possible to select the target shooting room R first and associate the console C with the target shooting room R. Further, when the console C and the shooting room R are associated with each other in a one-to-one correspondence like the console C1 and the shooting room R1 in FIG. 1, the shooting room after the operator clicks the determination button h13. The display of the screen for selecting R may be omitted.

  When the target shooting room R is selected on the screen for selecting the shooting room R, the console C is subsequently present in the target shooting room R from the management device S (see FIGS. 1 and 2). Information on the radiation image capturing apparatus 1 is obtained, and various icons I are displayed on the display unit Ca as illustrated in FIGS. 18 and 19.

  Specifically, in this embodiment, as shown in FIG. 18 and FIG. 19, on the left side of the selection screen H <b> 2, the notation of “standing position” and “prone position” is surrounded by a rectangular frame line. Icons I-51A and I-51B corresponding to the bucky device 51A for position photographing and the bucky device 51B for position photographing are respectively displayed. In addition, on the right side of the selection screen H2, icons I-1a to I-1c corresponding to the radiation image capturing apparatuses 1 existing in the imaging room Ra are displayed, and the icons I-1a to I-1c are displayed. Numbers 1 to 3 are attached and displayed in the respective rectangular frame lines.

  In this embodiment, if the radiographic imaging device 1 is not loaded in the bucky device 51, the console C displays the frame line of the icon I corresponding to the bucky device 51 with a broken line ("standing position" in FIG. 18). “I-51A,“ recumbent position ”I-51B and“ standing position ”I-51A in FIG. 19), and the bucky device 51 displays that the radiation imaging apparatus 1 is not loaded. Yes.

  In addition, the console C has the radiographic imaging device 1 loaded in the bucky device 51 (more precisely, the connector 39 of the radiographic imaging device 1 is connected to the connector 51c of the notification means 51b in the imaging room R). Case), the frame line of the icon I corresponding to the Bucky device 51 is displayed as a solid line.

  Then, the inside of the frame is colored and displayed in a predetermined color (refer to “Spine position” I-51B in FIG. 19), and an icon is displayed to indicate that the radiographic imaging device 1 is loaded in the bucky device 51. It is like that. In FIG. 19, the number, resolution, and the like of the radiographic image capturing apparatus 1 loaded in the position-capturing bucky device 51 </ b> B are displayed in the vicinity of the “prone position” icon I- 51 </ b> B.

  In the present embodiment, for example, by clicking the icon I-1 corresponding to the radiographic image capturing apparatus 1 shown in FIG. 18 or FIG. 19, the radiographic image capturing apparatus 1 is selected as a radiographic image capturing apparatus to be used in the future. Can be done. As described above, when the selection switch 38 of the radiographic image capturing apparatus 1 is pressed, the radiographic image capturing apparatus 1 can be selected as a radiographic image capturing apparatus to be used from now on.

  The console C is identification information of the radiographic imaging device 1 from the cradle 55 that is a registration unit of the radiographic room R, for example, when the radiographic imaging device 1 is newly brought into the associated radiographic room R. When the cassette ID is notified, an icon I-1 corresponding to the radiation image capturing apparatus 1 is newly displayed on the selection screen H2 of the display unit Ca of the console C.

  Further, for example, after clicking the icon I-1c corresponding to the radiation image capturing apparatus 1 of number 3 shown in FIG. 18, the icon I-51B corresponding to the bucky apparatus 51B for the supine position imaging is clicked, or It is possible to specify in advance that the radiographic image capturing apparatus 1 of No. 3 is to be loaded in the bucky apparatus 51B for positional imaging by dragging and dropping the icon I-1c onto the icon I-51B. It is like that. When operated in this way, the selection screen H2 is switched from the state of FIG. 18 to the state of FIG.

  In the present embodiment, when the radiographic imaging device 1 to be loaded in the bucky device 51 is designated in advance on the selection screen H2 of the console C in this way, the radiographing room R selected from the console C at that point in time A signal indicating that the bucky device 51 has been designated is transmitted to the console 57 in the photographing room R.

  When the signal is transmitted, the console 57 activates the radiation generating device 52A (see FIG. 12), and at the same time, designates a bucky device 51 (for example, for lying position imaging) specified based on the transmitted signal. The radiation generating device 52A is moved so that radiation can be appropriately applied to the bucky device 51B), the radiation direction is adjusted, and the diaphragm (not shown) is adjusted so that radiation is irradiated within a predetermined range of the bucky device 51. The radiation generator 52 is adjusted so that an appropriate dose of radiation is emitted.

  If comprised in this way, it will become possible to start the radiation generator 52 beforehand by operation with the console C, and it will become possible to take a radiographic image immediately in the stage which the operator moved to the imaging room R. There is an advantage such as.

  Note that, as described above, the operator who has moved to the radiographing room R, despite specifying that the radiographic imaging device 1 is loaded into the bucky device 51 on the selection screen H2 of the console C, For example, when shooting is performed without loading the device 1 in the Bucky device 51, it is possible to perform a process such as issuing a sound and warning.

  Although not shown in FIGS. 18 and 19, when a portable radiation generator 52B (see FIG. 12) exists in the imaging room R, a corresponding icon I is displayed on the selection screen H2 of the console C. In the same manner as in the case of the radiation generator 52A, the portable radiation generator 52B can be activated by operating the console C.

  The above is the situation when the operator operates the console C prior to radiographic imaging. After the operator moves to the imaging room R, for example, the selection switch 38 of the radiographic imaging apparatus 1 is pressed. When a selection signal indicating that the radiographic imaging apparatus 1 has been selected is transmitted from the radiographic imaging apparatus 1, the console C is colored with an icon I-1 corresponding to the radiographic imaging apparatus 1 on the selection screen H2. The fact that the radiographic imaging device 1 has been selected is displayed by being displayed.

  As described above, the connector 51c of the notification means 51b is connected to the connector 39 of the radiographic image capturing apparatus 1 in the radiographing room R by the operator (see FIG. 13), and from the radiographic image capturing apparatus 1 via the antenna apparatus 41. The Bucky ID and the cassette ID of the radiation image capturing apparatus 1 are transmitted to the console C.

  At this time, for example, when the radiation image capturing apparatus 1 of number 3 in FIG. 18 is connected to the notifying means 51b corresponding to the bucky apparatus 51B for the supine position imaging, the console C shows a selection screen H2 in FIG. The radiographic imaging device 1 is switched from the state shown in FIG. 19 to the state shown in FIG. 19 indicating that the radiological imaging device 1 is loaded in the bucky device 51B.

  On the other hand, when the radiographic image capturing based on the radiographing order information is completed in the associated radiographing room R, the above-described thinning data Dt is transmitted from the radiographic image capturing device 1 via the antenna device 41 and the base station 54. Then, the console C refers to the base station ID added to the thinning data Dt and transfers the thinning data Dt to the base station 54, that is, the radiographing room R in which the radiographic imaging is performed. Yes.

  At this time, the thinned data Dt is also displayed on the display unit Ca of the console C as a preview image. It is also possible to configure so that this display is performed only when there is an operation by the operator. Further, it is also possible to configure so that the thinned data Dt created from the image data D photographed based on the photographing order information is stored in the storage unit Cb in association with the photographing order information.

  In addition, after the thinned data Dt is transmitted as described above, the console C receives the corresponding image data D that is the basis for creating the thinned data Dt and the dark read value d read in the dark reading process. When transmitted from the radiographic image capturing apparatus 1 via the antenna device 41 or the base station 54, the data is stored in the storage means Cb in association with each imaging order information.

  On the console C, image processing is performed based on the image data D and the dark reading value d, and a final diagnostic radiation image based on the imaging order information is generated. When the image is generated, the console C stores the final diagnostic radiographic image in the storage unit Cb in association with the imaging order information.

  In the present invention, the radiographic image capturing apparatus 1 is carried from the image capturing room R1 to the image capturing room R2, for example, and the radiographic image capturing apparatus 1 is inserted into the cradle 55 that is a registration unit of the image capturing room R2, and When a cassette ID, which is identification information of the radiographic imaging apparatus 1, is notified to the management apparatus S or the console C, the radiographic imaging apparatus 1 is displayed on the selection screen H2 in the console C associated with the radiographic room R2. The icon I-1 corresponding to the radiographic image capturing apparatus 1 is deleted from the selection screen H2 on the console C associated with the imaging room R1. This point will be described in the description of the management apparatus S described below.

  The management device S (see FIG. 1 and the like) includes a server computer or the like in which a CPU, a ROM, a RAM, an input / output interface and the like (not shown) are connected to a bus. The management device S is connected to a storage means Sa composed of a hard disk or the like. The storage means Sa is provided with a shooting room ID which is identification information of the shooting room R and the shooting room R. A table in which the base station ID of the base station 54 is associated is stored in advance.

  The management apparatus S receives various information via the base station 54, via the console C in the systems shown in FIGS. 1 and 3, and via the network N in the systems shown in FIGS. , The imaging room ID of the imaging room R corresponding to the base station ID of the base station 54 added to the information with reference to the table is determined, and the information is transmitted from the imaging room R from which the information is determined. It is to be determined.

  The management apparatus S associates the cassette ID, which is identification information of the radiographic imaging apparatus 1, with the imaging room ID, which is identification information of the imaging room R, so that the radiographic imaging apparatus 1 is among the plurality of imaging rooms R1 to R4. Which imaging room R is present or which imaging room R is not present is managed.

  Specifically, the radiographic imaging device 1 is brought into the radiographing room R and inserted into a cradle 55 that is a registration unit, and a cassette ID that is identification information of the radiographic imaging device 1 is transmitted from the cradle 55 via the base station 54. When notified together with the base station ID of the base station 54, the management apparatus S determines the radiographing room ID which is identification information of the radiographing room R corresponding to the base station ID of the base station 54, and the radiographing room ID and the radiographic image. The cassette ID of the photographing apparatus 1 is associated with and stored in the storage unit Sa.

  At that time, when the radiographic imaging apparatus 1 is newly introduced into the radiographic imaging system 100, the radiographing room ID and the cassette ID of the radiographic imaging apparatus 1 newly introduced as described above are used. Is stored in the storage means Sa in association with each other. However, if the cassette ID of the radiographic imaging apparatus 1 has already been used in the radiographic imaging system 100 and has been associated with the radiographic room ID of another radiographic room R before that, the storage means Sa The association between the imaging room ID of the previous imaging room R and the cassette ID of the radiation image capturing apparatus 1 is discarded.

  By the way, as described above, when the radiographic imaging apparatus 1 is newly brought into the imaging room R and the cassette ID of the radiographic imaging apparatus 1 is notified from the cradle 55 of the imaging room R, the imaging is performed. The console C associated with the room R newly displays the icon I-1 corresponding to the radiographic image capturing apparatus 1 on the selection screen H2.

  However, the console C associated with the other radiographing room R in which the radiographic imaging apparatus 1 previously existed cannot grasp that the radiographic imaging apparatus 1 has been taken out from the radiographic room R. Therefore, although the radiographic image capturing apparatus 1 no longer exists in the radiographing room R, it still corresponds to the radiographic image radiographing apparatus 1 on the selection screen H2 of the console C associated with the radiographing room R. Icon I-1 to continue to be displayed.

  In such a state, for example, the icon I-1 corresponding to the radiographic image capturing apparatus 1 that no longer exists in the imaging room R on the selection screen H2 of the console C is the icon I-51 corresponding to the bucky apparatus 51 (that is, the book In the embodiment, an operation such as drag-and-drop is performed on I-51A or I-51B (the same applies hereinafter), and it is specified that the radiographic image capturing apparatus 1 is loaded into, for example, a bucky apparatus 51B for supine position imaging. In this case, the radiation generator 52A is activated so that the console C can irradiate the bucky device 51, and there is a possibility that inconveniences such as wasteful power consumption and accidental radiation may occur. is there.

  Therefore, in the management apparatus S, the cassette ID of the radiographic imaging apparatus 1 notified from the cradle 55 of the imaging room R as described above is associated with the imaging room IDs of the other imaging rooms R before that. In such a case, the association between the imaging room ID of the other imaging room R and the cassette ID of the radiographic image capturing apparatus 1 in the storage unit Sa is discarded. At the same time, the cassette ID of the radiographic imaging apparatus 1 is transmitted together with the deletion signal to the console C associated with the other radiographing room R, and the radiographic image is displayed on the console C from the selection screen H2. The icon I-1 corresponding to the cassette ID of the photographing apparatus 1 is deleted.

  That is, if the icons I-1a to I-1c corresponding to the radiation image capturing apparatus 1 are displayed on the selection screen H2 of the display unit Ca of the console C as shown in FIG. When the radiographic imaging device 1 with the number 3 is carried from the imaging room R to another imaging room R, the radiation with the number 3 is newly displayed on the selection screen H2 of the console C associated with the imaging room R. The icon I-1c corresponding to the image capturing apparatus 1 is displayed, and the icon I-1c corresponding to the number 3 radiographic image capturing apparatus 1 is deleted from the selection screen H2 of the original console C as shown in FIG. Is done.

  Further, even when the radiographic image capturing apparatus 1 having the number 3 is displayed as being loaded in the bucky device 51B for the supine imaging as shown in FIG. 19, the radiographic image capturing apparatus 1 having the number 3 is displayed. When it is carried from the radiographing room R to another radiographing room R and registered in the cradle 55, the radiographic image of number 3 is taken from the selection screen H2 of the original console C as shown in FIG. A display indicating that the radiographic imaging device 1 is loaded from the icon I-51B of the buckling device 51B for the supine photographing in which the device 1 is loaded (that is, the solid line and coloring of the frame of the icon I-51B) ) Is deleted, and the icon I-52B corresponding to the bucky device 51B for position photographing returns to the original broken line state (that is, the state where the radiographic image capturing device 1 is not loaded).

  If comprised in this way, in the console C corresponding to the imaging | photography room R where the said radiographic imaging apparatus 1 was brought in and inserted in the cradle 55, it corresponds newly to the said radiographic imaging apparatus 1 on the selection screen H2. The icon I-1 is displayed, and the icon I-1 corresponding to the radiographic image capturing apparatus 1 is deleted from the selection screen H2 of the console C corresponding to the radiographing room R where the radiographic image capturing apparatus 1 is taken out. Is done.

  In addition, when the deletion signal and the cassette ID of the radiographic imaging apparatus 1 are transmitted from the management apparatus S to the original console C, the selection screen H2 is not displayed on the display unit Ca of the original console C. In some cases. In that case, when the original console C receives a deletion signal or the like, the icon I- corresponding to the radiographic imaging apparatus 1 is stored in its own memory in which information of contents to be displayed as the selection screen H2 is temporarily stored. By deleting the information 1, the icon I-1 corresponding to the radiographic imaging apparatus 1 is not displayed on the selection screen H2 when the next display of the selection screen H2 is instructed.

  Next, the operation of the radiographic image capturing system 100 according to the present embodiment will be described.

  As described above, in the radiographic imaging system 100 according to the present embodiment, as in the radiographic imaging system described in Patent Document 1, it is required to provide a display unit on each support base of the radiographic imaging apparatus. First, the cradle 55 (registration means) provided with the display means 55b is simply installed in the photographing room R. Therefore, it is possible to save the trouble of providing a display unit on each support base.

  When radiographic imaging is performed, the thinning data Dt for preview is transmitted from the radiographic imaging apparatus 1 to the console C via the base station 54, and the thinning data Dt is transmitted from the console C via the base station 54 to the cradle. 55. In this way, a preview image of an image obtained by radiography immediately after radiographic imaging is displayed on the display means 55b of the cradle 55 in the imaging room R.

  Therefore, it is not necessary for an operator such as a radiologist who has taken an image in the imaging room R to leave the imaging room R and see the preview image displayed on the display screen Ca of the console C. The operator can operate the X-ray irradiation switch in the front room Rb of the photographing room R, return to the photographing room Ra from the front room Rb for the next photographing, and view the preview image while staying in the photographing room R. It becomes possible. Therefore, the radiographic image capturing system 100 according to the present embodiment is very convenient for the operator.

  In addition, since an operator in the photographing room R can see the preview image on the spot, it is determined whether or not the subject is correctly photographed by the radiographic image photographing device 1, and the necessity of re-photographing is immediately determined. It becomes possible to judge. For this reason, the patient is not allowed to wait for a long time until the necessity of re-photographing is determined, and the burden on the patient can be reduced. In addition, when the X-ray irradiation switch is operated, it takes a very short time to leave the patient alone in the imaging room Ra, and the patient can be sufficiently cared for.

  On the other hand, when the radiographic imaging device 1 brought into the imaging room R is inserted into the cradle 55 that is a registration unit, the cradle 55 reads the cassette ID that is identification information of the radiographic imaging device 1. Then, the information on the cassette ID is notified to the management apparatus S via the base station 54. The management device S stores the notified cassette ID and the shooting room ID, which is identification information of the shooting room R, in association with each other in the storage unit Sa.

  Further, as shown in FIG. 1 and the like, when there are a plurality of imaging rooms R (R1 to R4), the management apparatus S notifies the cassette ID information of the radiographic imaging apparatus 1 via the base station 54. Then, the radiographing room R associated with the base station 54 is determined from the base station ID added to the cassette ID information, and the radiographic image radiographing apparatus and the radiographing room ID as identification information of the radiographing room R are identified. One cassette ID (identification information) is associated and stored in the storage means Sa.

  If the cassette ID that is the identification information of the radiographic image capturing apparatus 1 is associated with the imaging room ID that is the identification information of the other imaging room R before that, the management apparatus S associates the cassette ID. Is discarded. In this way, the management apparatus S accurately manages in which imaging room R the radiographic image capturing apparatus 1 exists or in which imaging room R the radiographic image capturing apparatus 1 does not exist. .

  Therefore, it is possible to accurately grasp in which imaging room R the radiographic image capturing apparatus 1 exists, and to reliably obtain the image data of the target patient from the target radiographic image capturing apparatus 1. It is possible to accurately process the image data of the target patient on the console C.

  Further, for example, the radiographic imaging device 1 is in the first radiographic room R on the console C side even though the radiographic imaging device 1 is carried from the radiographing room R to another radiographing room R. Judging and acquiring image data of another person from the target patient from another radiographic image capturing apparatus 1 in the first imaging room R, and erroneously processing the image data of the other person as the image data of the target patient. It is possible to avoid the occurrence of a malfunction in system control.

  In addition, each imaging room R is provided with a registration means (cradle 55) having a display means 55b, and only by providing a management device S composed of a server or the like for managing information from them, system control can be performed as described above. It is possible to properly avoid the malfunction of the system and to properly operate the system. In addition, it is possible to construct a system at low cost in terms of cost simply by providing a registration unit (cradle 55) including the display unit 55b and a management device S.

  As described above, according to the radiographic image capturing system 100 according to the present embodiment, a registration unit (cradle 55) including the display unit 55b is installed in the imaging room R or a server or the like is installed in the imaging system R. A system can be configured simply by installing the management device S. Therefore, the system can be easily constructed.

  When radiographic imaging is performed, the preview thinning data Dt is automatically transmitted from the radiographic imaging apparatus 1 to the console C, and the thinning data Dt transferred from the console C is automatically displayed on the display means of the registration means. 55b. Therefore, the X-ray irradiation switch operation is performed in the front room Rb of the radiographing room R, the operator returns to the radiographing room Ra from the front room Rb for the next radiographing, and an operator such as a radiographer in the radiographing room Ra is on the spot The preview image can be viewed, and it is possible to determine whether or not re-shooting is necessary, so that the next shooting can be quickly started. Therefore, it becomes very convenient for the operator. In addition, when the X-ray irradiation switch is operated, it takes a very short time to leave the patient alone in the imaging room Ra, and the patient can be sufficiently cared for.

  Further, when the radiographic image capturing apparatus 1 is registered by the registration means (cradle 55) in the photographing room R, the identification information (cassette ID) is notified to the management apparatus S via the base station 54, and the management apparatus S The notified identification information of the radiographic image capturing apparatus 1 and the identification information (imaging room ID) of the imaging room R are stored in the storage unit Sa in association with each other. In addition, when the identification information of the radiographic image capturing apparatus 1 is associated with the identification information of another imaging room R before that, the management apparatus S discards the association.

  Therefore, the management apparatus S can accurately manage in which imaging room R the radiographic image capturing apparatus 1 exists or in which imaging room R the radiographic image capturing apparatus 1 does not exist. Become. In addition, it is possible to accurately grasp in which imaging room R the target radiographic image capturing apparatus 1 exists, and to reliably acquire target patient image data from the target radiographic image capturing apparatus 1. .

  Since the image data of the target patient can be reliably obtained from the target radiographic image capturing apparatus 1 in this manner, for example, the radiographic image capturing apparatus 1 different from the original radiographic image capturing apparatus 1 that images the target patient. Therefore, it is possible to accurately avoid the occurrence of a system control problem such that the image data of another person is acquired from the image data and erroneously processed as the image data of the target patient. Appropriate operation can be achieved.

  In addition, it goes without saying that the present invention is not limited to the present embodiment and can be appropriately changed.
