Description

[Technical Field]

[0001] The present invention relates to a radiation image display device, a radiation image display program, and a radiation image display method. [Background technology]

[0002] In a radiation image display device that displays a list of multiple radiographic imaging conditions and a list of multiple radiographic images obtained by imaging, it has been conventional to focus on a specific radiographic condition and a specific radiographic image from the displayed list (to make the display mode different from that of other radiographic conditions and radiographic images), or to shift the focus when moving to the next imaging, etc. (to stop focusing on the previously focused radiographic condition or radiographic image and newly focus on another radiographic condition or radiographic image) (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5435937 Summary of the Invention [Problem to be solved by the invention]

[0004] In addition to normal still image photography, radiation photography includes various other types of photography, such as long-length photography, which combines multiple radiation images obtained by photographing each part separately, and re-photography, which is a redo of photography when photography fails. Since the individual imaging operations included in the long imaging operation have different imaging conditions such as imaging regions, when performing long imaging, the radiation image display device displays each imaging condition separately (multiple times). Furthermore, since re-examination must be performed immediately after the failed exposure, when re-examination is performed, the radiation image display device will interrupt and display the exposure conditions for the re-examination before the exposure conditions for the next exposure that was originally scheduled. However, conventional radiation image display devices such as those described in Patent Document 1 are unable to properly shift the focus when the next shot is different from normal still image shooting (when the shooting conditions are displayed in a different format from normal still image shooting), making them difficult to use, for example by shifting the focus of the radiation image during long-length shooting.

[0005] The present invention has been made in consideration of the above-mentioned problems, and aims to ensure that the usability of a radiographic image display device, which focuses on the shooting conditions and the button that displays the radiographic image, and shifts the focus of the shooting conditions when moving on to the next shooting, is not impaired even when shooting differently from normal still image shooting. [Means for solving the problem]

[0006] In order to solve the above problems, the radiation image display device according to the present invention comprises: a display unit that displays a first focus display that displays one of the plurality of shooting conditions in a focused state, and a second focus display that displays a button that displays a shot image in a focused state; a display control unit that controls a transition between the first focus display and the second focus display after the photographing based on the one photographing condition is completed, The display control unit Depending on the type of photography to be performed after photography under the one photography condition, At least the second focus indication Control the transition of

[0007] The radiation image display program according to the present invention further comprises: a display step of displaying, on a display unit of the radiation image display device, a first focus display that displays one of the plurality of imaging conditions in a focused state and a second focus display that displays a button that displays an image that has been captured in a focused state; a display control step of controlling a transition between the first focus display and the second focus display after the photographing based on the one photographing condition is completed, In the display control step, Depending on the type of photography to be performed after photography under the one photography condition, At least the second focus indication Control the transition of

[0008] Further, the radiation image display method according to the present invention comprises: On the computer, a display process for displaying, on the display unit, a first focus display that displays one of the plurality of shooting conditions in a focused state, and a second focus display that displays a button that displays a captured image in a focused state; after the photographing based on the one photographing condition is completed, a display control process is executed to control a transition between the first focus display and the second focus display; In the display control process, Depending on the type of photography to be performed after photography under the one photography condition, At least the second focus indication The process of controlling the transition of the above is further executed. [Effects of the Invention]

[0009] According to the present invention, the usability of a radiographic image display device, which focuses on the shooting conditions and a button that displays multiple radiographic images, and shifts the focus of the shooting conditions when moving on to the next shooting, can be maintained even when shooting differently from normal still image shooting.

[0011] Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the technical scope of the present invention is not limited to the following embodiments and illustrated examples.

[0012] <1. Overview of the Radiography System> First, an overview of a radiation imaging system (hereinafter referred to as a system 100) according to this embodiment will be described. FIG. 1 is a block diagram illustrating an example of a system 100 .

[0013] As shown in FIG. 1, the system 100 includes a radiation detector (hereinafter, referred to as a detector 1) and a console 2. The system 100 according to this embodiment further includes a radiation generating device (hereinafter referred to as a generating device 3). The devices 1 to 3 are capable of communicating with each other via, for example, a communication network N (such as a local area network (LAN), a wide area network (WAN), or the Internet).

[0014] In addition, system 100 may be capable of communicating with a Hospital Information System (HIS), a Radiology Information System (RIS), a Picture Archiving and Communication System (PACS), an analysis device, etc., which are not shown.

[0015] [1-1. Radiation Generator] The generator 3 is for irradiating radiation. The generating device 3 includes a generator 31 , an irradiation instruction switch 32 , and a radiation source 33 . The irradiation instruction switch 32 may be connected to the generator 31 via an operation console (not shown).

[0016] When the irradiation instruction switch 32 is operated, the generator 31 applies a voltage to the radiation source 33 (tube) according to the preset imaging conditions (conditions related to the subject S (imaged part, imaging direction, physique, etc.), conditions related to the irradiation of radiation R (tube voltage, tube current, irradiation time, current-time product (mAs value), etc.)), and also passes a current according to the imaging conditions to the radiation source 33.

[0017] When a voltage is applied to the radiation source 33 from the generator 31 and a current is passed through it, the radiation source 33 generates radiation R (e.g., X-rays) of a dose corresponding to the applied voltage and the passed current in a manner corresponding to the applied voltage and the passed current.

[0018] [1-2. Radiation detector] Although not shown, the detector 1 includes a sensor substrate on which pixels are arranged two-dimensionally (in a matrix), each pixel having a radiation detection element that generates an electric charge according to the dose when exposed to radiation R and a switch element that stores and releases the electric charge, a scanning circuit that switches each switch element on and off, a readout circuit that reads out the amount of electric charge released from each pixel as a signal value, a control unit that generates a radiographic image from the multiple signal values ​​read out by the readout circuit, and a communication unit that transmits data on the generated radiographic image and various signals to the outside and receives various information and signals.

[0019] The detector 1 stores and releases electric charges and reads out signal values ​​in synchronization with the timing at which radiation R is irradiated from the generator 3, thereby generating a radiological image according to the dose of the irradiated radiation R.

[0020] [1-3. Console] The console 2 is a radiation image display device, and is composed of a PC, a dedicated device, and the like. In addition, the console 2 sets various imaging conditions (conditions related to the subject S (imaged part, imaging direction, physique, etc.), conditions related to the irradiation of radiation R (tube voltage, tube current, irradiation time, current-time product (mAs value), etc.)) in at least one of the detector 1 and the generator 3. The console 2 also displays the imaging conditions and the radiographic images obtained by imaging. Details of this console 2 will be described later.

[0021] [1-4. Outline of operation of the radiography system] The system 100 configured in this manner operates as follows. First, the console 2 outputs imaging conditions to at least one of the detector 1 and the generator 3 . The device to which the imaging conditions are input (at least one of the detector 1 and the generator 3) sets the input imaging conditions. When the generator 3 irradiates the diagnostic area of ​​the subject S located between the radiation source 33 of the generator 3 and the detector 1, which are arranged opposite each other with a gap between them, with radiation R, the detector 1 generates a radiological image showing the diagnostic area and transmits the image data to the console 2. When the console 2 receives the image data, it outputs the imaging conditions for the next imaging and displays the obtained radiation image.

[0022] [1-5. Radiography Systems and Others] So far, the system 100 has been described in which the console 2 also functions as a radiation image display device, but the radiation image display device may also be provided independently. Specifically, as shown in FIG. 2, in addition to the detector 1 and generator 3, a radiation imaging system (hereinafter referred to as system 100A) may be configured with a console 2A that does not have a radiation image display function and an independently provided radiation image display device 4. The system 100 may be installed in an imaging room, or the generator 3 and the console 2 may be configured as a mobile unit called a mobile cart. Furthermore, the systems 100 and 100A may be those in which the detector 1 and the generator 3 are integrated together (for example, a CT (Computed Tomography) device or the like). Furthermore, the system 100 may be provided with an imaging table (not shown) for holding the detector 1 (for imaging in an upright position, for imaging in a supine position, for imaging in a long length, etc.).

[0023] <2. Details of the console (radiographic image display device)> Next, the console 2 included in the system 100 (radiation image display device 4 included in the system 100A) will be described in detail. FIG. 3 is a block diagram showing the console 2 (radiation image display device 4), and FIGS. 4 to 10 are image diagrams showing examples of screens displayed by the console 2 (radiation image display device 4).

[0024] [2-1. Specific console configuration] As shown in FIG. 3, the console 2 (radiation image display device 4) includes a control unit 21, a storage unit 22, a communication unit 23, a display unit 24, and an operation unit 25. The units 21 to 25 are electrically connected by a bus or the like.

[0025] The control unit 21 is composed of a CPU (Central Processing Unit), RAM (Random Access Memory), and the like. The CPU of the control unit 21 reads out various programs stored in the memory unit 22, expands them in the RAM, executes various processes in accordance with the expanded programs, and centrally controls the operation of each part of the console 2 (radiation image display device 4).

[0026] The storage unit 22 is configured by a non-volatile memory, a hard disk, or the like. The storage unit 22 also stores various programs (including a radiological image display program) executed by the control unit 21, parameters required for executing the programs, and the like. The storage unit 22 may be capable of storing image data of a radiographic image acquired from another device (for example, the detector 1, etc.).

[0027] The communication unit 23 is composed of a communication module and the like. The communication unit 23 is configured to send and receive various signals and data to and from other devices (detector 1, generator 3, etc.) connected by wire or wirelessly via a communication network N (LAN (Local Area Network), WAN (Wide Area Network), Internet, etc.).

[0028] The display unit 24 displays various screens used for diagnosis by the user. The display unit 24 is configured by, for example, an LCD (Liquid Crystal Display), a CRT (Cathode Ray Tube), or the like. The display unit 24 displays a radiographic image or the like in accordance with the image signal received from the control unit 21 .

[0029] The operation unit 25 is, for example, a keyboard (cursor keys, numeric input keys, various function keys, etc.), a pointing device (mouse, etc.), a touch panel laminated on the surface of the display unit 24, etc. The operation unit 25 outputs a control signal to the control unit 21 in response to an operation performed by the user.

[0030] In addition, the console 2 may not be equipped with a display unit 24 or an operation unit 25, and may instead receive control signals from an input device provided separately from the console 2, for example, via a communication unit 23, or output image signals to a display device (monitor) provided separately from the console 2. Furthermore, if the other device (e.g., an analysis device, etc.) is equipped with a display unit and an operation unit, it may be configured to receive control signals from the operation unit of the other device and output image signals to the display unit of the other device (the display unit and operation unit may be shared with the other device).

[0031] [2-2. Console Operation] The control unit 21 of the console 2 (radiation image display device 4) configured as above operates as follows.

[0032] (Display processing) For example, when a predetermined condition is met, the control unit 21 executes the display process in accordance with the radiographic image display program. The specified conditions include, for example, the power of the console 2 (radiation image display device 4) being turned on, receiving an imaging order from another device, acquiring image data from another device, receiving a specified control signal from another device, and performing a specified operation on the operation unit 25. In this display process, the control unit 21 causes the display unit 24 to display a photographing screen such as that shown in FIG. 4(a), for example.

[0033] The photographing screen has a first button display area R1, a second button display area R2, and an image display area R3. The shooting screen according to this embodiment further includes an image adjustment menu display area R4, a subject information display area R5, a preparation status display area R6, and an operation button display area R7.

[0034] The first button display area R1 is an area that displays a plurality of first buttons B1. The control unit 21 displays the first buttons B1 in the first button display area R1 in a number corresponding to the imaging order acquired from the other device. The first buttons B1 according to this embodiment are arranged in a vertical line. Furthermore, the control unit 21 causes each first button B1 to display a shooting condition. The imaging condition displayed on the first button B1 shown in FIG. 4 and the like is the imaging region, but the control unit 21 may be configured to display other imaging conditions on the first button B1.

[0035] Additionally, the first button display area R1 displays a first focus display F1. The first focus display F1 displays one of a plurality of shooting conditions in a focused state. The first focus display F1 according to this embodiment displays the shooting conditions for the next shooting or the current shooting in a focused state. As described above, since the shooting conditions are displayed on each first button B1, the first focus display F1 is also displayed when the first button B1 is focused. The first focus display F1 according to this embodiment refers to changing the color of the button border, or superimposing a frame of the same shape as the button border but a different color on the button border. The focus may be changed by thickening the border of the button, changing the color of the entire button, or the like.

[0036] The second button display area R2 is an area in which a plurality of second buttons B2 are displayed. The control unit 21 displays the same number of second buttons B2 as the number of first buttons B1 in the second button display area R2. The second buttons B2 according to this embodiment are arranged next to the first buttons B1. Furthermore, the control unit 21 causes each second button B2 to display a captured radiographic image. The second button B2 according to this embodiment is configured to display the radiological image in the form of a thumbnail.

[0037] Additionally, the second button display area R2 displays a second focus display F2. The second focus display F2 is displayed in a state in which the second button B2, which displays a radiographic image captured under the imaging conditions displayed on the adjacent first button B1, is focused. The second focus display F2 in this embodiment, like the first focus display F1, refers to changing the color of the button border or superimposing a frame of the same shape as the button border but a different color on the button border. The aspect of the second focus indication F2 may be different from that of the first focus indication F1.

[0038] The image display area R3 is an area in which a radiation image is displayed. The control unit 21 displays the radiographic image corresponding to the thumbnail of the second button B2 on which the second focus indication F2 is displayed in the image display region R3. The image adjustment menu display area R4 is an area where various operation buttons and the like for adjusting the radiation image displayed in the image display area R3 are displayed. The subject information display area R5 is an area for displaying information about the subject (for example, the subject's name, etc.). The preparation status display area R6 is an area where the preparation status for the next radiation imaging is displayed. When the detector 1 and the generator 3 are ready to take a photograph based on the photographing conditions of the first button B1 on which the first focus display F1 is displayed, a message is displayed indicating that photographing is possible (for example, the text "Photographing is possible" is displayed).

[0039] The operation button display area R7 is an area where buttons for performing various operations on the shooting screen are displayed. The buttons for performing various operations include a reject button B3 and a transition restriction button B4. When the rejected button B3 is operated while a radiographic image is displayed in the image display region R3, the control unit 21 determines that the displayed radiographic image is a rejected image (determines that the capture of the radiographic image was unsuccessful).

[0040] The control unit 21 and the display unit 24 perform the above-described operations to function as a display means. Furthermore, the execution of the display process by the control unit 21 corresponds to the display step in the radiographic image display method.

[0041] (Display control processing) Furthermore, the control unit 21 executes a display control process as the shooting progresses. Specifically, before the first shooting starts, the control unit 21 displays the shooting conditions for the shooting to be performed on each first button B1 in the first button display area R1, as shown in FIG. 4(a), for example. At this time, the control unit 21 displays a first focus display F1 on the first button B1 (here, the top one) that displays the shooting conditions for the first shooting. In addition, the control unit 21 is in a state where it can output the shooting conditions corresponding to the first button B1 on which the first focus display F1 is displayed to at least one of the detector 1 and the generator 3 via the communication unit 23. Furthermore, the control unit 21 displays a second focus display F2 on the second button B2 adjacent to the first button B1 that displays the photographing conditions for the first photographing. At this stage, since no radiation images have been obtained, thumbnails are not displayed on any of the second buttons B2, including the second button B2 next to the first button B1 that displays the shooting conditions for the initial shot.

[0042] When the imaging based on the initial imaging conditions (normal still image imaging: chest) is completed, the control unit 21 displays a thumbnail T of the radiographic image captured under the initial imaging conditions as shown in FIG. 4(b). 11 is displayed on the second button B2 next to the first button B1 that displays the initial shooting conditions. At this time, the control unit 21 continues to display the second focus indication F2 that has been displayed on the second button B2. At this time, the control unit 21 also transitions the first focus display F1 to the first button B1 (here, the second from the top) that displays the imaging conditions for the second imaging (normal still image imaging: abdomen). In addition, the control unit 21 controls the thumbnail T of the second button B2 on which the second focus indication F2 is displayed. 11 Radiography image I (obtained in the first exposure) corresponding to 11 is displayed in the image display area R3. This allows the user to adjust the radiographic image and determine whether it is defective immediately after capturing the image, and also allows the user to adjust the radiographic image and capture the next image in parallel.

[0043] So far, we have explained the operation of taking multiple normal still images without any problems, but the images taken using system 100 may or may not be normal still image images. For this reason, the control unit 21 is further configured to execute processing to control the transition destination of at least one of the first focus display F1 and the second focus display F2 depending on the type of shooting to be performed after shooting under one shooting condition.

[0044] Specifically, when the type of imaging to be performed after imaging under one imaging condition is normal still image imaging (first type of imaging), when imaging under one imaging condition is completed, the control unit 21 transitions the first focus display F1 to a first button B1 (here, the third button from the top) that displays the imaging conditions for the next imaging, as shown in FIG. 4(c), and displays a thumbnail T of the radiation image captured under one imaging condition. 12The second focus display F2 is transitioned to the second button B2 (here, the second from the top) that displays the following. Furthermore, the control unit 21 selects the radiographic image I corresponding to the thumbnail of the second button B2 on which the second focus indication F2 is displayed. 12 is displayed in the image display area R3.

[0045] On the other hand, when the type of imaging to be performed after imaging under one imaging condition is the second type of imaging, the control unit 21 transitions the first focus display F1 to a first button B1 that displays imaging conditions other than the imaging conditions for the next imaging, or transitions the second focus display F2 to a second button B2 other than the second button B2 that displays a radiographic image captured under one imaging condition. The second type of photography includes long-length photography, re-photography, and the like. Long-length radiography is a method of capturing a plurality of radiographic images and combining the captured radiographic images to generate a combined image. Re-shooting is a process of retrying photography when photography under one photography condition has failed (resulted in a bad photo).

[0046] Specifically, when the type of photography to be performed after photography under one photography condition (here, still image photography of the chest shown in Figure 5(a)) is long-length photography, the control unit 21 displays a first focus display F1 on each of multiple (three) first buttons B1 that display the photography conditions for each photography included in the long-length photography, as shown in Figures 5(b) to (e). Furthermore, as the long-length imaging progresses, the control unit 21 generates thumbnails T of the radiographic images before they are combined. 221 ~T 223 are displayed sequentially on the second button B2. On the other hand, the control unit 21 prohibits the transition of the second focus display F2 (the thumbnail T of the radiographic image before combining) until the long-length imaging is completed. 221 ~T 223 (The second focus display F2 does not transition to the second button B2 that displays the second focus display F2.) During this time, the control unit 21 selects the radiographic image I (obtained by imaging under one imaging condition) corresponding to the thumbnail of the second button B2 on which the second focus indication F2 is displayed.21 is displayed in the image display area R3.

[0047] Then, after the long-length photography is completed, the control unit 21 displays a first button B1 (here, the second from the top) indicating that the image is a combined image between the first button B1 (here, the top one) that displays one photography condition and the first button B1 that displays the photography condition for the next long-length photography, as shown in FIG. 5(f), and displays a thumbnail T of the combined image next to the first button B1. 22 A second button B2 is displayed. Then, the control unit 21 generates a thumbnail T 22 The second focus display F2 is transitioned to the second button B2 that displays. Furthermore, the control unit 21 selects the radiographic image (combined image I) corresponding to the thumbnail of the second button B2 on which the second focus display F2 is displayed. 22 ) is displayed in the image display area R3.

[0048] Note that Figure 5 illustrates an example of performing long-length photography after still image photography is completed, but even when performing another long-length photography after one long-length photography is completed, the control unit 21 performs display control in a flow similar to that when performing long-length photography after still image photography is completed, as shown in Figure 6, for example. That is, when one long-length photographing is completed, a first button B1 (here, the top one) is displayed to indicate that the combined image is obtained by one long-length photographing, and a thumbnail T of the combined image is displayed. 31 When the second button B2 displaying the combined image is displayed, the control unit 21 transitions the second focus display F2 to the second button B2 displaying the combined image, as shown in FIG. 6(a). Then, while each of the images included in the next long-length photography is being taken (until the next long-length photography is completed and the combined image obtained by the next long-length photography is displayed), the control unit 21 displays the thumbnail T of the combined image as shown in FIGS. 6(b) and 6(c). 31 The second focus indicator F2 continues to be displayed on the second button B2 on which the icon is displayed. During this time, the control unit 21 controls the thumbnail T of the second button B2 on which the second focus indication F2 is displayed. 31The corresponding radiographic image (combined image I obtained by one long-length exposure) 31 ) is displayed in the image display area R3.

[0049] Note that Figures 5 and 6 illustrate an example in which the transition of the second focus display F2 is restricted until the long-length shooting is completed, but the control unit 21 may also be configured to transition the second focus display F2 as each shot included in the long-length shooting progresses, as shown in Figure 7, for example, based on a predetermined transition restriction release operation being performed.

[0050] On the other hand, when the type of photography to be performed after photography under one photography condition (for example, long photography corresponding to the first button B1, which is the second to fifth from the top in FIG. 8(a)) is re-photographing (when the user selects the combined image I in FIG. 8(a)), the control unit 21 41 When the user judges the image to be unsuccessful by looking at the image and operates the rejected image button B3 (until the button B3 is operated, the first focus display F1 is displayed on the first button B1 which displays the imaging conditions for the next imaging (here, still image imaging of the abdomen)), as shown in FIG. 8(b), a thumbnail T of the radiographic image obtained by imaging under one imaging condition (the imaging that resulted in the rejected image) is displayed. 41 ,T4 11 ~T 413 A mark M (for example, x) indicating that the image has been rejected is displayed on the second button B2. Then, the control unit 21 displays a first button B1 that displays the shooting conditions for the next shot (of the failed shot) below the first button B1, and displays a second button B2 that does not display a thumbnail next to the first button B1. Note that here, the first button, which displays the shooting conditions for the next shot after the one originally planned (shooting conditions for still image shooting of the abdomen shown in Figure 8(a)), does not fit on the shooting screen and is no longer visible.

[0051] Then, the control unit 21 transitions the first focus display F1 to the first button B1 that displays the photographing conditions for re-photographing. The control unit 21 also displays a thumbnail T of a radiographic image (here, the image of the chest corresponding to the top first button B1) taken before the radiography under one radiographic condition. 42 The second focus display F2 is transitioned to the second button B2 that displays. Then, the control unit 21 selects the thumbnail T of the second button B2 on which the second focus indication F2 is displayed. 42 Chest radiographic image I corresponding to 42 is displayed in the image display area R3.

[0052] If no imaging has been performed before the imaging under the failed imaging condition, the control unit 21 may, for example, as shown in FIG. 8(c), generate a thumbnail T of the radiographic image that has been determined to be an unsuccessful imaging condition (here, the combined image). 41 The second button B2 continues to display the second focus display F2. Then, the control unit 21 selects the radiographic image (combined image I) corresponding to the thumbnail of the second button B2 on which the second focus display F2 is displayed. 41 ) is displayed in the image display area R3. Then, the control unit 21 selects the radiographic image I obtained by the imaging under one imaging condition (the imaging that resulted in the imaging failure). 41 and its thumbnail T 41 ,T4 11 ~T 413 A mark M (for example, x) indicating that the image has been rejected is displayed on the second button B2.

[0053] Also, Figure 8 illustrates an example of a case where a long-length photograph is re-taken, but even when a still image is re-taken, the control unit 21 performs display control in the same manner as in the case of a long-length photograph, as shown in Figure 9, for example.

[0054] In addition, when the transition restriction button B4 is operated, the control unit 21 prohibits the transition of the second focus display F2 even when the next shooting is completed and a thumbnail of the radiographic image obtained in the next shooting is displayed on the second button B2. For example, if the transition restriction button B4 is operated and the transition is restricted before the next photographing (for example, still image photographing of the abdomen shown in FIG. 10(a)) is started, the control unit 21 will operate the corresponding second button B2 to restrict the transition when the next photographing (still image photographing of the abdomen or part of the long-length photographing) is completed, as shown in FIG. 10(b). 41 ,T 42 Even if the thumbnail T of the still image of the chest obtained by the still image capturing of the chest is displayed, the second focus display F2 is not changed. 43 (The second focus indicator F2 continues to be displayed on the second button B2 where the icon is displayed.) This allows a user who finds it difficult to adjust the radiation image in accordance with the progress of imaging to make adjustments at their own pace.

[0055] Even when the transition of the second focus display F2 is restricted, when a second button B2 that is not the second focus display F2 is operated, the control unit 21 transitions the second focus display F2 to the operated second button B2, as shown in Figure 10 (c). Although not shown in the figure, a thumbnail T of the radiographic image obtained during the long-length imaging is 42 ,T 44 When the second button B2 on which is displayed is operated, the control unit 21 also transitions the second focus display F2 to the operated second button B2.

[0056] The control unit 21 and the display unit 24 perform the above-described operations to form a display control means. Furthermore, the execution of the display control process by the control unit 21 corresponds to a display control step in the radiation image display method.

[0057] <3. Effects> As described above, the console 2 (radiation image display device 4) of this embodiment includes a display unit 24 that displays a first focus display F1 and a second focus display F2, and a control unit 21 (display control unit) that, after shooting based on one shooting condition is completed, transitions the first focus display F1 to the shooting condition (first button B1) for the next shooting, and transitions the second focus display F2 to the second button B2 that displays the radiation image shot under the one shooting condition, and the control unit 21 controls the transition destination of at least one of the first focus display F1 and the second focus display F2 depending on the type of shooting to be performed after shooting under the one shooting condition. Therefore, the console 2 (radiation image display device 4) can maintain its ease of use even when performing imaging that differs from normal still image imaging.

[0058] <4.Other> It goes without saying that the present invention is not limited to the above-described embodiments, and can be modified as appropriate within the scope of the present invention.

[0059] For example, the system 100 may be capable of one-shot long-length imaging in which a plurality of detectors 1 are used simultaneously to generate a plurality of radiographic images by irradiating radiation R once and combine the images. In this case, the operation of the console 2 (radiation image display device 4) when performing one-shot imaging can be the same as when performing normal still image imaging. System 100 may also support video capture, producing multiple frames. In this case, as in the case of single-shot imaging, the operation of the console 2 (radiation image display device 4) when imaging a moving image can be the same as when imaging a normal still image.

[0060] Furthermore, for example, in the above description, examples have been disclosed in which a hard disk or a semiconductor nonvolatile memory is used as a computer-readable medium for storing the radiation image display program according to the present invention, but the present invention is not limited to this example. Other computer-readable media include portable recording media such as CD-ROMs. Furthermore, carrier waves can also be used as a medium for providing data for the radiation image display program according to the present invention via a communication line.
