Description

  The present invention relates to a radiographic image detection apparatus that generates radiographic image data by detecting radiation typified by X-rays, and a radiographic imaging system using the radiographic image detection apparatus.

  In the field of medical diagnosis, a reading device that reads radiation image data by scanning a phosphor plate built in a CR cassette with excitation light, and a control device (console for acquiring radiation image data read by the reading device) ) And a CR (Computed Radiography) system have been put into practical use (see Patent Document 1). In the CR system of Patent Document 1, a plurality of radiation imaging rooms are each provided with a control device, and one reading device is connected to the plurality of control devices. Then, when the CR cassette irradiated with radiation in each radiography room is read by the reader, the controller that registered the CR cassette is identified based on the cassette ID of the CR cassette, and the controller can be obtained by the reader. The radiographic image data is transmitted and displayed.

  In addition, introduction of a large-scale CR system in which a plurality of reading devices and a plurality of control devices are connected via a network has been proposed (see Patent Document 2). According to the large-scale CR system of Patent Document 2, no matter which reading device is used to read the CR cassette, the radiation image data is transmitted and displayed to the control device that has registered the CR cassette. Therefore, for example, when radiography is performed across a plurality of radiography rooms and a plurality of CR cassettes used for imaging are read by a plurality of readers, radiation image data is displayed on one control device. In addition, since the reading operation of a plurality of CR cassettes can be performed in a distributed manner by a plurality of reading devices, the working efficiency can be improved.

  Further, in place of the above-described CR cassette, radiation detector elements that are two-dimensionally arranged on a substrate are built in, and radiation signals that can output an electrical signal corresponding to the radiation dose applied to the radiation detector elements can be output. An FPD (Flat Panel Detector) device as an image detection device has been proposed. If this FPD device is used, it is possible to obtain radiation image data directly without irradiating excitation light and reading a radiation image, so that the system itself can be made smaller than when a CR cassette is used. In addition, the photographing work is also smooth.

Conventionally, the FPD apparatus is installed in the radiation imaging room, but a cassette type FPD apparatus enabling portable and wireless communication has been devised in order to enable imaging of a wide range of parts more quickly. (See Patent Document 3). In this Patent Document 3, a plurality of FPD devices are arranged in a radiation imaging room in a state of being stored in a cradle (cassette storage box), and an operator inputs an imaging region by a control device provided outside the imaging room. In addition, it is disclosed that an FPD device optimum for the imaging region is selected from FPD devices housed in a cradle, and the selected FPD device is displayed on the cradle. Then, the operator confirms the display of the cradle, takes out the FPD device from the cradle, and uses the FPD device for photographing. In this way, by displaying the selected FPD device on the cradle, it is possible to prevent the operator from mistaken the FPD device and to ensure that the selected FPD device can perform shooting. Yes.

  However, Patent Document 3 is configured to use the FPD device in the same radiation imaging room as the radiation imaging room in which the cradle is installed, and has a plurality of radiation imaging rooms as in the large-scale CR system described above. It is not assumed that the image is shot across, and a workflow for this purpose is not disclosed at all. Therefore, if the content disclosed in Patent Document 3 is applied to a large-scale CR system as it is, an operator mistakes the FPD device or duplicate selection that simultaneously selects the same FPD device with a plurality of control devices. Is feared to occur.

  Accordingly, the present invention has been made in view of the above-described problems, and an object of the present invention is to provide an optimal radiographic image capturing system when the FPD device is applied to a mode in which radiographing is performed across radiographic rooms.

In order to achieve the above object, a radiographic imaging system of the present invention includes an image data generation unit that generates radiation image data by detecting radiation transmitted through a subject, and radiographic image data generated by the image data generation unit.

  The plurality of radiation image detection devices 6a to 6e generate radiation image data by detecting radiation irradiated from the radiation image capturing device 3 and transmitted through the patient 12, and a flat panel detector (Flat Panel Detector) is formed in the cassette. : FPD) is a portable cassette FPD apparatus that accommodates an imaging panel, also called FPD.

  Hereinafter, the structure of the radiation image detection apparatus 6 will be described with reference to FIGS. 3 and 4. FIG. 3 is a perspective view of the radiation image detection apparatus 6. As shown in FIG. 3, the radiation image detection device 6 includes a housing 61 that protects the inside, and is configured to be portable as a cassette.

  An imaging panel 62 serving as an image data generation unit that converts irradiated radiation into an electrical signal is formed in layers inside the casing 61. A light emitting layer (not shown) that emits light according to the intensity of the incident radiation is provided on the radiation irradiation side of the imaging panel 62.

  The light emitting layer is generally called a scintillator layer. For example, a phosphor is a main component, and based on incident radiation, an electromagnetic wave having a wavelength of 300 nm to 800 nm, that is, visible light to ultraviolet light to infrared light. Output electromagnetic waves (light).

  As the phosphor used in the light emitting layer, for example, a material based on CaWO4 or the like, or a material in which a luminescent center substance is activated in a matrix such as CsI: Tl, Gd2O2S: Tb, or ZnS: Ag can be used. . Further, when the rare earth element is M, a phosphor represented by a general formula of (Gd, M, Eu) 2 O 3 can be used. In particular, CsI: Tl and Gd2O2S: Tb are preferable because of high radiation absorption and light emission efficiency. By using these, a high-quality image with low noise can be obtained.

  The electromagnetic wave (light) output from the light emitting layer is converted into electric energy and accumulated on the surface opposite to the surface on which the radiation of the light emitting layer is irradiated, and an image signal based on the accumulated electric energy is stored. A signal detection unit 600 in which photoelectric conversion units that perform output are arranged in a matrix is formed. Note that a signal output from one photoelectric conversion unit is a signal corresponding to one pixel serving as a minimum unit constituting the radiation image data.

  Here, a circuit configuration of the imaging panel 62 will be described. FIG. 4 is an equivalent circuit diagram of the signal detection unit 600 in which the photoelectric conversion units are two-dimensionally arranged. As shown in FIG. 4, the photoelectric conversion unit includes a photodiode 601 and a thin film transistor (TFT) 602 that extracts electric energy accumulated in the photodiode 601 as an electric signal by switching. The extracted electrical signal is amplified to a level that can be detected by the signal readout circuit 608 by the amplifier 603. Note that the amplifier 603 is connected to a reset circuit (not shown) composed of a TFT 602 and a capacitor, and a reset operation is performed to reset the accumulated electrical signal by switching on the TFT 602. The TFT 602 may be either an inorganic semiconductor type used in a liquid crystal display or the like, or an organic semiconductor type. Moreover, although the case where the photodiode 601 is used as a photoelectric conversion element is illustrated, a solid-state image sensor other than a photodiode may be used for the photoelectric conversion element.

  The scanning lines Ll and the signal lines Lr are disposed between the photoelectric conversion units constituting the pixels so as to be orthogonal to each other. A TFT 602 is connected to the photodiode 601 described above, and one end of the photodiode 601 on the side to which the TFT 602 is connected is connected to the signal line Lr. On the other hand, the other end of the photodiode 601 is connected to one end of an adjacent photodiode 601 arranged in each row, and is connected to a bias power source 604 through a common bias line Lb. One end of the bias power source 604 is connected to the control unit 60, and a voltage is applied to the photodiode 601 through the bias line Lb according to an instruction from the control unit 60.

  The TFTs 602 arranged in each row are connected to a common scanning line Ll, and the scanning line Ll is connected to the control unit 60 via a scanning drive circuit 609 that sends a pulse to each photoelectric conversion element. Similarly, the photodiodes 601 arranged in each column are connected to a signal readout circuit 608 that is connected to a common signal line Lr and controlled by the control unit 60. In the signal readout circuit 608, an amplifier 603, a sample hold circuit 605, an analog multiplexer 606, and an A / D converter 607 are arranged on a common signal line Lr in order from the imaging panel 62.

  At the time of signal reading, the scanning drive circuit 609 is driven to energize the TFT 602, whereby the charge accumulated in the anode of the photodiode 601 is transmitted to the amplifier 603 as an electric signal. This electric signal is amplified to a level that can be detected by the signal readout circuit 608 by the amplifier 603. The voltage value of the amplifier 603 is temporarily held by the sample hold circuit 605 and then applied to the analog multiplexer 606.

  In the analog multiplexer 606, the obtained voltage value is converted into a serial electric signal and transmitted to the A / D converter 607. The A / D converter 607 converts this electric signal into digital data. In this way, radiation image data is created by the imaging panel 62.

  Returning to FIG. 3, the radiation image detection apparatus 6 includes a light emitting unit 64, an image storage unit 66, a power supply unit 67, a charging terminal 69, and the like.

  The light emitting unit 64 is provided at one end of the back surface of the housing 61 and incorporates an LED (Light Emitting Diode) whose light emission is controlled by the control unit 60. As will be described later, by making the light emitting unit 64 emit light, it is possible to notify the operator which radiation image detection device 6 is selected. Further, when the light emitting unit 64 is caused to emit light, the light emission cycle is made different depending on each of the plurality of consoles 7a, thereby informing the operator which radiographic image detection device 6 has been selected by which console 7a. be able to. That is, the control unit 60 and the light emitting unit 64 cooperate to function as notification means in the present invention.

  The image storage unit 66 includes a rewritable memory such as a nonvolatile memory or a flash memory, and stores radiation image data output from the imaging panel 62. The image storage unit 66 may be a built-in memory or a removable memory such as a memory card.

  The power supply unit 67 supplies power to a plurality of drive units (the control unit 60, the imaging panel 62, the light emitting unit 64, the image storage unit 66, etc.) constituting the radiation image detection apparatus 6. The power source 67 is a rechargeable battery 671 made of, for example, a manganese battery, an alkaline battery, a lithium battery, a nickel cadmium battery, etc., and can be recharged, for example, made of a nickel cadmium battery, a nickel hydride battery, a lithium ion battery, a fuel cell, a solar battery, etc. And a rechargeable battery 672.

  As described above, by providing the spare battery 671 in addition to the rechargeable battery 672, the radiographic image detection device 6 has at least a minimum when the charge amount of the rechargeable battery 672 is insufficient or while the rechargeable battery 672 is replaced. It is possible to supply limited power. The rechargeable battery 672 can be charged by connecting the charging terminal 69 to the cradle 7b.

  FIG. 5 is a block diagram illustrating a configuration of a main part of the radiation image detection apparatus 6. As shown in FIG. 5, the control system of the radiation image detection apparatus 6 includes a control unit 60, an imaging panel 62, a light emitting unit 64, an image storage unit 66, a power supply unit 67, a ROM 81, a RAM 82, a communication unit 83, and the like. Are connected by a bus 84. Of these, the imaging panel 62, the light-emitting unit 64, the image storage unit 66, and the power supply unit 67 have been described above, and a description thereof will be omitted here.

  The control unit 60 includes, for example, a CPU and the like, reads a control program stored in the ROM 81, develops it in a work area formed in the RAM 82, and controls each unit of the radiation image detection device 6 according to the control program. .

  The ROM 81 is configured by a nonvolatile semiconductor memory or the like, and stores a control program executed by the control unit 60, various programs, and the like.

  The RAM 82 forms a work area for temporarily storing various programs, input or output data, parameters, and the like that can be executed by the control unit 60 read from the ROM 81 in various processes controlled by the control unit 60. .

  The communication unit 83 communicates various information with the console 7a via the network 8, and receives selection instruction information transmitted from the console 7a via the network 8 and the cradle 7b. That is, the communication unit 83 functions as a transmission unit and a reception unit in the present invention.

  FIG. 7 is a flowchart for explaining the operation flow of the radiographic image capturing system 1. The operation of the radiographic image capturing system 1 will be described with reference to FIG. It is assumed that imaging order information (including patient information and imaging information) is input in advance by a doctor or a receptionist, and the imaging order information is stored in the external storage device of the server 2. In addition, a plurality of consoles are connected to the radiation image capturing system 1, and a plurality of radiation image detection devices 6a to 6e can be controlled by the plurality of consoles. The console 7a will be taken up and explained.

  First, when radiographic imaging is performed, the console 7a receives imaging order information stored in the server 2, and stores the imaging order information in the storage unit 21 (step S1). An operator such as a doctor or a radiographer displays a list of imaging order information stored in the storage unit 21 on the display unit 17 and operates the input operation unit 18 to cope with the patient 12 who is to perform radiography from now. The photographing order information to be selected is selected (step S2).

  Next, the console 7a inquires about the characteristics of the plurality of radiological image detection apparatuses 6a to 6e and the availability status (step S3). In general, each of the plurality of radiation image detection devices 6a to 6e has unique characteristics such as a cassette size, a type of scintillator in the imaging panel 62, and a pixel defect, and is not necessarily suitable for all imaging conditions. . In addition, some of the plurality of radiation image detection devices 6a to 6e are already in use by other operators, and may not be used for the current imaging. Therefore, in step S3, an inquiry is made as to the specific characteristics of the radiation image detection device 6 and the availability status (detection means). In response to the inquiry from the console 7a, the radiation image detection device 6 transmits the characteristic information and the availability information to the console 7a (step S4).

  When the console 7a receives the characteristic information and the availability information from the plurality of radiation image detection devices 6a to 6e, the console 7a stores the characteristic information and the availability information in the storage unit 21 (step S5). Then, based on the imaging information (information necessary for imaging such as the imaging site, imaging direction and method) included in the imaging order information selected in step S2, and the characteristic information stored in the storage unit 21, From among the plurality of radiation image detection devices 6a to 6e, a radiation image detection device suitable for the current imaging is determined (step S6; determination means). Further, the determination result and the availability information are displayed on the display unit 17 of the console 7a (step S7).

  FIG. 6 is a diagram illustrating an example when a list of the plurality of radiation image detection devices 6a to 6e is displayed on the display unit 17 of the console 7a. In this figure, “appropriate imaging” 171 indicates whether or not the radiation image detection devices 6a to 6e are suitable for the current imaging, that is, the determination result in step S6, and “use / non-use” 172 indicates the radiation image detection device. 6 indicates whether or not it is currently used by another operator, that is, the detection result in step S3. The operator operates the input operation unit 18 while confirming the display on the display unit 17, and selects the radiation image detection apparatus 6 that is suitable for imaging and is not currently used (step S8; selection means).

  Upon receiving the selection instruction information from the input operation unit 18, the console 7a transmits the selection instruction information SIG1 to the selected radiation image detection device 6 (step S9). Moreover, the light emission period (for example, 1 second, 3 second) at the time of making the light emission part 64 of the radiographic image detection apparatus 6 light-emit according to each some console is preset, and the light emission period corresponding to the said console 7a is set. It displays on the display part 17 (step S10).

  When the selected radiation image detection device 6 receives the selection instruction information from the console 7a by the communication unit 83, the light emission unit 64 is caused to emit light at the light emission period displayed on the display unit 17 in step S10 (step S11). Notifies that the radiation image detection device 6 has been selected by the console 7a. Further, any one of the light emitting units 7b1 to 7b5 corresponding to the slot in which the radiological image detection device 6 is accommodated in the cradle 7b is caused to emit light at the light emission period displayed on the display unit 17 in step S10.

  And an operator confirms lighting equivalent to the light emission period displayed on the display part 17 of the light emission part 64 of the selected radiographic image detection apparatus 6, and the light emission parts 7b1-7b5 of the cradle 7b, and the said radiographic image The detection device 6 is taken out from the cradle 7b. When detecting that the radiation image detecting device 6 has been taken out from the cradle 7b, the light emitting unit 64 is turned off (step S12), and the cradle 7b turns off the light emitting units 7b1 to 7b5. Then, the radiation image detection device 6 is carried to the radiation imaging room 30 and imaging is performed (step S13).

  As described above, in the present embodiment, the selected radiation image detection device 6 includes a plurality of radiation image detection devices by turning on the light emission unit 64 of the radiation image detection device 6 or the light emission units 7b1 to 7b5 of the cradle 7b. Since it is configured to notify which one of 6a to 6e, the operator can prevent the radiological image detection device 6 from being mistaken.

  Moreover, the light emission period of the light emission part 64 or light emission part 7b1-7b5 is set according to the some console, the light emission period according to the console 7a which selected the radiographic image detection apparatus 6 is displayed on the display part 17, and is displayed. The light emitting unit 64 or the light emitting units 7b1 to 7b5 are turned on similarly to the light emission period displayed on the unit 17. Therefore, it is possible to clearly display the correspondence between the console 7a that has selected the radiation image detection device 6 and the selected radiation image detection device 6, and a plurality of radiation image detection devices 6 are selected at the same time. Even in such a case, it is possible to prevent mistakes in the radiation image detection device 6.

  The radiographic image detection device 6 used for radiographing is based on radiographing information necessary for radiographing the radiographic region, radiographing direction, method, and the like and unique characteristic information of the radiographic image detection devices 6a to 6e. Therefore, the radiation image detection device 6 that is optimal for imaging is provided.

  In addition, since the radiographic image detection device 6 used for imaging is configured to be selected in consideration of information on whether or not it is currently used by another operator, it is used by another operator. The radiological image detection device 6 is not erroneously selected. Usually, in the radiographic imaging system 1 including a plurality of consoles 7a, a plurality of operators operate the respective consoles 7a at the same time, and a plurality of radiographic image detection devices 6a to 6e housed in the cradle 7b are selected as appropriate. And will be used. Even in such a situation, in the present embodiment, the configuration is selected after confirming the usage situation, and therefore the same radiation image detection device 6 is not simultaneously selected.

  In the above embodiment, it is detected whether or not the plurality of radiation image detection devices 6a to 6e are currently usable (step S3), and whether or not the plurality of radiation image detection devices 6a to 6e are suitable for imaging. (Step S6), the detection result and the discrimination result are displayed on the display unit 17 of the console 7a (step S7), and then the operator operates the input operation unit 18 while confirming the display on the display unit 17. Thus, the radiation image detection device 6 is selected (step S8). However, it is not always necessary for the operator to select by operating the input operation unit 18. For example, the console 7 a is configured to automatically select the radiation image detection device 6 in consideration of the determination result and the detection result. You may do it.

  In addition, when the operator selects the radiological image detection device 6, what characteristics of the radiological image detection device 6 are accommodated in the cradle 7b, and which radiographic image detection device 6 is most suitable for imaging. May be selected without performing discrimination based on the characteristic information and the shooting information.

  Moreover, although the light emission part was provided in the radiographic image detection apparatus 6 and the cradle 7b, you may comprise so that a light emission part may be provided only in either one. For example, if each slot of the cradle 7b has a collation function with the radiographic image detection device 6, the light emitting unit of the cradle 7b corresponding to the selected radiographic image detection device 6 can emit light.

  Further, in order to prevent mistakes in the radiological image detection device 6, the light emission period in the light emitting unit 64 or the light emitting units 7b1 to 7b5 is set differently depending on each of the plurality of consoles. When the selection instruction information is transmitted, the light emission cycle may be set by the input operation unit 18 of the console 7a. As another method for preventing mistakes, a plurality of color LEDs may be incorporated in the light emitting unit 64 or the light emitting units 7b1 to 7b5, and the light emitting colors of the LEDs may be different depending on each of the plurality of consoles. I do not care.

  In addition, the radiation image detection device 6 and the cradle 7b are configured to notify that the LED is selected by causing the built-in LED to emit light. However, as another example, it is also possible to notify using sound or vibration. is there. In the case of notification using sound, for example, an operator ID of the operator is registered in advance in the console 7a, and the operator ID is transmitted to the selected radiographic image detection apparatus 6 together with selection instruction information. Then, when the radiological image detection apparatus 6 is taken out from the cradle 7b, the name of the operator who has selected the radiographic image detection apparatus 6 can be notified by sound. With this configuration, it is possible to prevent the radiation image detection device 6 from being mistaken among a plurality of operators.

  Further, the radiation image detection device 6 selected by the operator is notified by causing the light emission unit 64 of the radiation image detection device 6 or the light emission units 7b1 to 7b5 of the cradle 7b to emit light. However, the notification means in the present invention is not limited to this. For example, a display unit connected to the sterilization chamber 50 via the network 8 is provided, and the radiation image detection device 6 selected is displayed on the display unit. You may do it. Further, when the operator wears a head mount display, it may be configured to display which radiation image detection device 6 is selected on the head mount display. That is, as the notification means in the present invention, any configuration can be used as long as it can notify which radiation image detection device 6 is selected when the operator takes out the radiation image detection device 6. It doesn't matter.

  Further, the radiation image detection device 6 is mounted on the cradle 7b, and the generated radiation image data is transmitted to the console 7a by wired communication.
