In the radiological imaging system 10, the radiographic imaging unit 101 (radiation imaging apparatus) can transfer a radiographic image generated based on the received radiation. The radiation photographing unit 101 receives the radiation from the radiation generator 20, generates a digital image based on the received radiation, and transfers the generated radiation image. The radiographic imaging unit 101 has a control unit 103 that controls the acquisition of the radiographic image and the transfer of the radiographic image, and the control unit 103 continues the transfer or transfers the radiographic image based on the transfer status of the radiographic image. It is possible to determine whether to interrupt and control the transfer. The console 102 (control device) determines the radiographic imaging unit 101 to be used from among the plurality of radiographic imaging units, requests the radiographic imaging unit 101 to prepare for imaging, displays the digital image received from the radiographic imaging unit 101, and edits the image.

The console 102 (control device) includes an imaging control unit 1021, a reception control unit 1022, a display control unit 1023, and an operation detection unit 1024 as functional configurations thereof.

In the console 102 (control device), the imaging control unit 1021 requests the radiographic imaging unit 101 to prepare for imaging, sets a timeout time, controls imaging in the radiological imaging unit, and transfers and re-transfers captured image data. It is possible to control the transfer of. The reception control unit 1022 performs reception processing of the image (image data) transmitted from the radiography imaging unit 101, and continues the reception of the radiographic image or ends the reception of the radiological image based on the transfer status of the radiographic image. It is possible to determine whether to do so. The display control unit 1023 is connected to the display device 30, and performs display control for displaying the image received by the reception control unit 1022 on the display device 30. The operation detection unit 1024 is connected to the operation device 40, and receives input information from the operation device 40 by the operator.

The communication between the radiography unit 101 and the console 102 (control device) may be wired communication or wireless communication. Further, in the case of wireless communication, either the radiographic imaging unit 101 or the console 102 (control device) may take on the function of the access point.

(Processing procedure of console 102)
Next, the processing procedure of the console 102 of the radiography system 10 will be described. FIG. 2 is a flowchart showing a processing procedure of the console 102 until the console 102 identifies the radiography unit 101 used for radiography in the radiography imaging system 10, performs radiography, and finishes radiography.

First, in step S101, the imaging control unit 1021 of the console 102 determines the radiation imaging unit 101 to be used for imaging from among the plurality of radiation imaging units (hereinafter, also simply referred to as “imaging unit”), and the imaging control unit 1021 Notifies the determined radiography unit 101. FIG. 5 is a diagram showing a display example of the display device 30, and for example, on the screen displayed on the display device 30 as shown in FIG. 5, the state of the radiography unit used for radiography, patient information, and radiography conditions are displayed. It is displayed. A linked shooting unit is set for the shooting conditions. For example, in the display example of FIG. 5, the shooting unit A corresponds to the shooting condition 1 (shooting part: CHESTPA, time: 500 msec), and the shooting condition 5 (shooting part: CHESTPA, time: 600 msec) is set. The shooting unit B corresponds. The console 102 can determine the radiographic imaging unit 101 to be used for radiographic imaging based on the selection of imaging conditions input by the GUI or an external operating device. In the display example of FIG. 5, the shooting condition 1 is selected (selected), and the state display 501 of the shooting unit (in this case, the shooting unit A) used for shooting under the shooting condition 1 is “preparing for shooting”. Is displayed.

In step S102, the imaging control unit 1021 sets the interruption determination time based on the image size of the radiography imaging unit 101. Here, the interruption determination time includes the first interruption determination time for determining the interruption of the transfer of the reduced image data and the second interruption determination time for determining the interruption of the transfer of the generated radiation image data (all image data). The interruption judgment time of is included. The second interruption determination time is longer than the first interruption determination time. The imaging control unit 1021 sets the first interruption determination time (first timeout time a) and the second interruption determination time (second timeout time b) corresponding to the radiography imaging unit 101 determined in step S101. It is transmitted to the radiography unit 101. Here, the first interruption determination time (first timeout time a) is the time required to display the reduced image data obtained by reducing the image generated by the photographing unit on the display device 30 (reduced image data display time). The second interruption determination time (second timeout time b) is the time required to display the radiation image (all image data) generated by the photographing unit on the display device 30 (all image data display time). ) Corresponds.

FIG. 9A is a diagram illustrating the relationship between the image size and the image data display time, and FIG. 9B is a diagram illustrating a combination of the radiography section and the timeout time in the embodiment. In FIG. 9B, a combination of the image size set in each of the radiographic imaging units and the first timeout time a and the second timeout time b is illustrated. The imaging control unit 1021 has a non-volatile storage unit that stores the tables shown in FIGS. 9A and 9B, and the first interruption determination time corresponding to the radiography imaging unit 101 determined in step S101. (First time-out time a) and second interruption determination time (second time-out time b) are acquired from the table of FIG. 9B and transmitted to the radiography imaging unit 101. Since the imaging unit A is selected in step S101, the imaging control unit 1021 sets “8000 msec” to the radiography imaging unit 101 as the first interruption determination time (first timeout time a) corresponding to the imaging unit A. In response to this, "33000 msec" is transmitted to the radiography imaging unit 101 as the second interruption determination time (second timeout time b).

The imaging control unit 1021 may determine the first timeout time a and the second timeout time b from the image data display time that matches the image size of the imaging unit. For example, the image size of the photographing unit A is 2800 (pixel) × 3408 (pixel), and the photographing control unit 1021 has an image data display time corresponding to this image size (reduced image data display time 8000 msec, total image data display time). 33000 msec) is acquired from the table of FIG. 9A, and the radiation imaging unit 101 is used as the first interruption determination time (first timeout time a) and the second interruption determination time (second timeout time b). It is possible to send to.

Next, in step S103, the reception control unit 1022 receives the transferred image. The reception control unit 1022 starts receiving the image data when the radiography unit 101 starts transmitting the image data.

In step S104, the reception control unit 1022 determines whether or not the reception of the reduced image data is completed. If the reception of the reduced image data is completed (S104-Yes), the process proceeds to step S106. On the other hand, if the reception of the reduced image data is not completed (S104-No), the process proceeds to step S105. The reception control unit 1022 determines whether or not the reception of the reduced image data is completed, and in step S105, the reception control unit 1022 determines whether or not the radiography photographing unit 101 interrupts the image transfer. When the image transfer is interrupted in the radiography unit 101, the radiography unit 101 notifies the console 102 that the image transfer has been interrupted. The reception control unit 1022 can determine whether or not the radiography imaging unit 101 has interrupted the image transfer based on the notification transmitted from the radiography imaging unit 101. If the radiography unit 101 interrupts the image transfer (S105-Yes), the process proceeds to step S112.

On the other hand, if the radiography unit 101 does not interrupt the image transfer (S105-No), the process is returned to step S104, and the same process is executed in step S104. Then, when it is determined in step S104 that the reception of the reduced image data is completed (S104-Yes), the process proceeds to step S106. The reception control unit 1022 determines whether or not the reception of the reduced image data is completed, and when the reception of the reduced image data is completed, the display control unit 1023 causes the display device 30 to display the reduced image data.

That is, in step S106, the display control unit 1023 causes the display device 30 to display the reduced image data for which reception has been completed. Further, in step S107, the display control unit 1023 enables image editing on the reduced image data displayed on the display device 30. Here, FIG. 6 is a diagram showing a display example of reduced image data in the display device 30. For example, the display control unit 1023 displays the reduced image data on the display device 30 as shown in FIG. 6, and controls the display so as to enable image editing operations such as image cropping, image rotation, and image inversion. Do. The display control unit 1023 displays the image editing unit 601 for performing the image editing operation on the display screen of the display device 30, and based on the editing operation via the image editing unit 601, the image editing operation of the reduced image data. Is possible.

In the state where the reduced image data is displayed (FIG. 6), the shooting unit A has completed the transfer processing of the reduced image data, and the shooting unit A is in the state of transferring all the image data. The display control unit 1023 displays the status display 602 of the photographing unit A as "all image data is being transferred".

Next, in step S108, the reception control unit 1022 determines whether or not the reception of all image data is completed. If the reception of all image data is completed (S108-Yes), the process proceeds to step S110. On the other hand, if the reception of all image data is not completed (S108-No), the process proceeds to step S109.

In step S109, the reception control unit 1022 determines whether or not the radiography photographing unit 101 interrupts the image transfer. When the image transfer is interrupted in the radiography unit 101, the radiography unit 101 notifies the console 102 that the image transfer has been interrupted. The reception control unit 1022 can determine whether or not the radiography imaging unit 101 has interrupted the image transfer based on the notification transmitted from the radiography imaging unit 101. If the radiography unit 101 interrupts the image transfer (S109-Yes), the process proceeds to step S112. On the other hand, if the radiography unit 101 has not interrupted the image transfer (S109-No), the process is returned to step S108, and the same process is executed in step S108. Then, in step S108, when it is determined that the reception of all the image data is completed (S108-Yes), the process proceeds to step S110. The reception control unit 1022 determines whether or not the reception of the generated radiation image data (all image data) is completed, and displays when the reception of the generated radiation image data (all image data) is completed. The control unit 1023 causes the display device 30 to display the radiation image data (all image data). The display control unit 1023 displays the image editing unit 801 for performing the image editing operation on the display screen of the display device 30, and based on the editing operation via the image editing unit 801, the image editing operation of the reduced image data. Is possible.

That is, in step S110, the display control unit 1023 causes the display device 30 to display all the image data for which reception has been completed, and in step S111, the reception control unit 1022 ends the image data reception process. When the transfer of image data is interrupted and an instruction to end the image transfer is input, the shooting control unit 1021 ends the transfer of the interrupted image in this step. Here, FIG. 8 is a diagram showing a display example of all image data in the display device 30. The display control unit 1023 displays, for example, all the image data on the display device 30 as shown in FIG. 8, and controls the display so as to enable image editing operations such as image cropping, image rotation, and image inversion. Do. The display control unit 1023 displays the image editing unit 801 for performing the image editing operation on the display screen of the display device 30, and based on the editing operation via the image editing unit 801, the image editing operation of all the image data. Is possible.

In the state where all the image data is displayed (FIG. 8), the transfer process of all the image data is completed in the photographing unit A, and in the display example of FIG. 8, the photographing condition 1 using the photographing unit A has been photographed. Is displayed as (802). Further, in the next shooting, the shooting condition 5 using the shooting unit B is displayed as selected (selected) (803). In FIG. 8, the state display 804 of the shooting unit (in this case, the shooting unit B) used for shooting under the shooting condition 5 is in a state of being displayed as “preparing for shooting”.

Next, in step S112, the reception control unit 1022 determines that the image transfer has been interrupted in steps S105 and S109, so that the image data reception process is interrupted.

In step S113, the reception control unit 1022 calculates the progress rate of image transfer indicating the rate at which the transfer is completed, based on the image size captured by the radiography photographing unit 101 and the image data for which the image transfer is completed. That is, the reception control unit 1022 calculates the progress rate (transfer progress rate) of the image transfer, which percentage of all the image data is received before the image transfer is interrupted. For example, as shown in FIG. 9, the image size taken by the photographing unit A is 2800 (pixel) × 3408 (pixel), and the reception control unit 1022 is an image with respect to this image size. It is possible to calculate the progress rate of image transfer (transfer progress rate) by acquiring the ratio of the image data for which the transfer has been completed. In this example, an example of the photographing unit A is shown, but the same applies even when another photographing unit shown in FIG. 9B is used.

Further, in step S114, the display control unit 1023 causes the display device 30 to display the image transfer progress rate (transfer progress rate) calculated in step S113 and a message notifying that the transfer has been interrupted. When the transfer is interrupted, the control unit 103 of the radiography photographing unit 101 outputs a notification indicating the interruption of the image transfer, and the display control unit 1023 causes the display device 30 to display the notification. Further, the display control unit 1023 causes the display device 30 to display the progress rate of the image transfer. Here, FIG. 7 is a diagram showing a progress rate (transfer progress rate) of image transfer in the display device 30 and a display example of a message notifying that the transfer has been interrupted. In the state where the image data transfer is interrupted (FIG. 7), the status display 703 of the photographing unit (in this case, the photographing unit A) used for shooting is displayed as "image transfer interrupted". .. The display control unit 1023 displays on the display screen of the display device 30 a retransfer instruction unit that instructs the retransfer of the image for which the image transfer has been interrupted and an end instruction unit that instructs the end of the image transfer. For example, as shown in FIG. 7, the display control unit 1023 displays a display screen of the display device 30 with a retransfer instruction unit 701 instructing the photographing unit to retransfer the image and an end instruction unit 702 instructing the end of the image transfer. It is possible to select whether to execute the image retransfer or end the image transfer based on the operation via the retransfer instruction unit 701 or the end instruction unit 702. When the retransfer instruction unit 701 instructs the retransfer of the image, the control unit 103 of the radiography imaging unit 101 performs transfer control so as to restart the interrupted transfer.

The operation detection unit 1024 receives the input information by the operator input via the retransfer instruction unit 701 or the end instruction unit 702, and inputs the input information to the photographing control unit 1021. The imaging control unit 1021 controls the radiography imaging unit based on the information input from the operation detection unit 1024. When the re-transfer instruction is input, the imaging control unit 1021 requests the radio-imaging unit 101 to re-transfer the interrupted image data, and causes the radio-imaging unit to execute the re-transfer of the interrupted image data. When the image transfer end instruction is input, the shooting control unit 1021 ends the interrupted image transfer.

In step S115, the imaging control unit 1021 determines whether or not to retransfer the interrupted image data based on the information input from the operation detection unit 1024. When the end instruction of the image transfer is input (when the button of the end instruction unit 702 in FIG. 7 is pressed by the operator), that is, when the retransfer is not performed (S115-No), the process proceeds to step S111. Then, in step S111, the photographing control unit 1021 ends the transfer of the interrupted image.

On the other hand, in the determination in step S115, when the retransfer instruction is input (when the button of the retransfer instruction unit 701 in FIG. 7 is pressed by the operator), that is, when the retransfer is performed (S115-Yes). ), The process proceeds to step S116.

In step S116, the imaging control unit 1021 requests the radiography imaging unit 101 to retransfer the interrupted image data, and causes the radiography imaging unit to execute the retransfer of the interrupted image data. Then, the process is returned to step S103, and in step S103, the reception control unit 1022 starts receiving the image data transferred again from the radiography imaging unit 101. The above processing is the processing procedure of the console 102.

(Processing procedure of radiography unit 101)
Next, the processing procedure of the radiographic imaging unit 101 of the radiological imaging system 10 will be described. FIG. 3 is a flowchart showing a processing procedure of radiography, image data transfer, interruption of transfer processing, and end of radiography, which is executed by the radiography imaging system 10 in the radiography system 10.

First, in step S201, when the radiological imaging unit 101 receives the notification to be used for imaging from the console 102, the radiological imaging unit 101 prepares for radiographic imaging.

In step S202, the radiography unit 101 receives the first interruption determination time (first timeout time a) and the second interruption determination time (second timeout time b) transmitted from the console 102.

Next, when the preparation for radiography is ready, in step S203, the radiography unit 101 starts radiography. The radiation imaging unit 101 may perform radiation imaging using a synchronization signal with the radiation generator 20, and the radiation imaging unit 101 starts radiography when the radiation from the radiation generator 20 is detected. You may.

After starting the radiography, in step S204, the radiography unit 101 receives the radiation and generates a digital image. Next, in step S205, the radiography unit 101 starts measuring the elapsed time t1 required for image transfer in order to transmit the generated digital image to the console 102. The radiography photographing unit 101 includes a measuring unit for measuring the elapsed time required for transferring the radiographic image, and the measuring unit measures the elapsed time from the start of the transfer of the radiographic image. In the present embodiment, the radiography imaging unit 101 transfers the generated radiological image (all image data) after the transfer of the reduced image data obtained by reducing the generated radiographic image is completed.

In step S206, the radiography imaging unit 101 first transfers the reduced image data. In step S207, the radiography unit 101 determines whether or not the transfer of the reduced image data is completed. When the transfer of the radiographic image is not completed, the control unit 103 of the radiographing unit 101 continues or transfers the radiographic image based on the comparison between the measured time and the set interruption determination time. To determine whether to interrupt. If the determination in step S207 does not complete the transfer of the reduced image data (S207-No), the process proceeds to step S208.

In step S208, the control unit 103 of the radiography imaging unit 101 determines whether or not the measured time (elapsed time t1) exceeds the first timeout time a (interruption determination time). When the elapsed time t1 exceeds the first timeout time a (interruption determination time) (S208-No), the process proceeds to step S212. That is, when the measured time (elapsed time t1) exceeds the set time (first timeout time a (interruption determination time)), the control unit 103 of the radiography imaging unit 101 interrupts the transfer. judge.

On the other hand, in the determination of step S208, if the elapsed time t1 does not exceed the first timeout time a (S208-Yes), the process is returned to step S206, and in step S206, the radiographing unit 101 performs the reduced image data. Transfer processing is executed. That is, if the measured time (elapsed time t1) does not exceed the set time (first timeout time a (interruption determination time)), the control unit 103 of the radiography imaging unit 101 continues the transfer. judge.

If the determination in step S207 indicates that the transfer of the reduced image data is completed (S207-Yes), the process proceeds to step S209.

In step S209, the radiography imaging unit 101 transfers all the image data acquired by imaging. In step S210, the radiography unit 101 determines whether or not the transfer of all image data has been completed. When the transfer of the radiographic image is not completed, the control unit 103 of the radiographing unit 101 continues or transfers the radiographic image based on the comparison between the measured time and the set interruption determination time. To determine whether to interrupt. If the determination in step S210 does not complete the transfer of the reduced image data (S210-No), the process proceeds to step S211.

In step S211 the radiography unit 101 determines whether or not the measured time (elapsed time t1) exceeds the second timeout time b (interruption determination time). When the elapsed time t1 exceeds the second timeout time b (interruption determination time) (S211-No), the process proceeds to step S212. That is, when the measured time (elapsed time t1) exceeds the set time (second timeout time b (interruption determination time)), the control unit 103 of the radiography imaging unit 101 interrupts the transfer. judge.

On the other hand, if the elapsed time t1 does not exceed the second timeout time b in the determination of step S211 (S211-Yes), the process is returned to step S209, and in step S209, the radiographing unit 101 performs all image data. Transfer processing is executed. That is, if the measured time (elapsed time t1) does not exceed the set time (second timeout time b (interruption determination time)), the control unit 103 of the radiography imaging unit 101 continues the transfer. judge.

If the determination in step S210 indicates that the transfer of all image data has been completed (S210-Yes), the process proceeds to step S214.

On the other hand, in step S212, since the elapsed time t1 exceeds the first time-out time a or the second time-out time b, the radiography unit 101 interrupts the image transfer. Then, in step S213, the radiography imaging unit 101 notifies the console 102 that the image transfer has been interrupted. That is, when the transfer is interrupted, the control unit 103 of the radiography unit 101 outputs a notification indicating the interruption of the image transfer. In the processing procedure (S105, S109) of the console 102 described above, the reception control unit 1022 determines whether or not the radiographic imaging unit 101 interrupts the image transfer based on the notification transmitted from the radiographic imaging unit 101. It is possible to judge.

In step S214, the radiographic imaging unit 101 ends the measurement of the elapsed time t1, and in step S215, the radiological imaging unit 101 ends the radiological imaging. The above processing is a processing procedure executed by the radiography imaging unit 101 until the radiography, the transfer of image data, the interruption of the transfer processing, and the end of the radiography.

Next, the procedure for retransferring the interrupted image data executed by the radiography unit 101 will be described.

FIG. 4 is a flowchart showing a procedure for retransferring image data executed by the radiography imaging unit 101 in the radiography imaging system 10.

In step S301, the radiography unit 101 receives a request for retransfer of image data from the console 102. The request for re-transfer transmitted from the console 102 corresponds to the request for re-transfer of the interrupted image data transmitted from the photographing control unit 1021 of the console 102 in step S116 of FIG. Upon receiving the request for retransfer, in step S302, the radiography unit 101 starts the image transfer, so that the measurement of the elapsed time t1 required for the image transfer is started.

In step S303, the radiography imaging unit 101 first transmits the reduced image data. In step S304, the radiography unit 101 determines whether or not the transfer of the reduced image data is completed. If the determination in step S304 does not complete the transfer of the reduced image data (S304-No), the process proceeds to step S305.

In step S305, the radiography unit 101 determines whether or not the elapsed time t1 exceeds the first timeout time a. When the elapsed time t1 exceeds the first timeout time a (S305-No), the process proceeds to step S310, and when the elapsed time t1 does not exceed the first timeout time a (S303-Yes). The process is returned to step S303, and in step S303, the radiography imaging unit 101 executes the transfer process of the reduced image data.

On the other hand, if the determination in step S304 indicates that the transfer of the reduced image data is completed (S304-Yes), the process proceeds to step S306.

In step S306, the radiography imaging unit 101 transfers all the image data acquired by imaging.

In step S307, the radiography unit 101 determines whether or not the transfer of all image data has been completed. If the determination in step S307 indicates that the transfer of all image data has not been completed (S307-No), the process proceeds to step S308.

In step S308, the radiography unit 101 determines whether or not the elapsed time t1 exceeds the second timeout time b. When the elapsed time t1 exceeds the second timeout time b (S308-No), the process proceeds to step S310, and when the elapsed time t1 does not exceed the second timeout time b (S308-Yes). The process is returned to step S306, and in step S306, the radiography unit 101 executes the transfer process of all image data.

On the other hand, if the determination in step S307 indicates that the transfer of all image data has been completed (S307-Yes), the process proceeds to step S309.

In step S310, since the elapsed time t1 exceeds the first time-out time a or the second time-out time b, the radiography unit 101 interrupts the image transfer. Then, in step S311 the radiographing unit 101 notifies the console 102 that the image transfer (retransfer) has been interrupted. In the processing procedure (S105, S109) of the console 102 described above, in the reception control unit 1022, the radiography unit 101 interrupted the image transfer (retransfer) based on the notification transmitted from the radiography unit 101. It is possible to determine whether or not.

In step S309, the radiography unit 101 ends the measurement of the elapsed time t1 and ends the process related to the retransfer of the interrupted image data. When the interrupted image data retransfer request is received again from the console 102 (S301), the radiography unit 101 executes the processing procedure of steps S301 to S311 described with reference to FIG. As described above, the timeout time from the start of image transfer to the display of reduced image data (first timeout time a) is set short, and the timeout time from the start of image transfer to the display of all image data (second timeout time). Set the timeout time b) longer. By setting the first timeout time a and the second timeout time b in this way, even in a situation where the communication path (communication environment) of image transfer is unstable, transfer can be performed quickly until the transfer of reduced image data. After the completion of the transfer of the reduced image data, it becomes possible to realize the radiography system 10 capable of reliably transferring all the image data even little by little.

When the control unit 103 of the radiation photographing unit 101 is instructed to retransfer the image from the retransfer instruction unit 701, the control unit 103 does not start from the interrupted pixel based on the pixel information indicating the interrupted pixel in the image data. It is possible to perform transfer control so as to transfer the image data to be transferred. For example, when the image transfer of the radiation photographing unit 101 is interrupted, the image received by the console 102 is stored in the storage unit in the console 102, and the control unit 103 of the radiation photographing unit 101 is a pixel indicating the interrupted pixel in the image data. Memorize information. The control unit 103 of the radiography photographing unit 101 may transfer the image again from the image data in the middle of the interruption based on the pixel information indicating the interrupted pixel in the image data. Alternatively, when the control unit 103 of the radiography imaging unit 101 is instructed to retransfer the image from the retransfer instruction unit 701, the control unit 103 performs transfer control so as to transfer the image data at the time of transfer disclosure from the beginning. It is possible. For example, the image received by the console 102 is not stored, the control unit 103 of the radiation photographing unit 101 does not store the pixel information indicating the interrupted pixel in the image data, and the image retransfer of the radiation photographing unit 101 is the first. It may be transferred from the image data.

(Second Embodiment)
Next, the configuration of the radiography system of the second embodiment will be described. In the radiography system of the present embodiment, the first interruption determination time (first timeout time a) and the second interruption determination time (second timeout time b) set in the radiation imaging unit 101 are different. The first interruption determination time (a + α) and the second interruption determination time (b + β) are set in the console 102, and the reception of the image data is continued based on the transfer status of the radiographic image data. Alternatively, a configuration for determining whether to end the reception of image data will be described. The configuration of the radiography system of the second embodiment is the same as the configuration of the radiography system described in the first embodiment (FIG. 1).

FIG. 10 shows a processing procedure of the console 102 in the radiological imaging system 10 according to the second embodiment, in which the console 102 identifies the radiographic imaging unit 101 used for imaging, performs radiographic imaging, and ends the radiological imaging. It is a flowchart which shows.

First, in step S401, the imaging control unit 1021 of the console 102 determines the radiation imaging unit 101 to be used for imaging from among a plurality of radiation imaging units (simply also referred to as “imaging unit”), and the imaging control unit 1021 determines Notify the determined radiography unit 101.

In step S402, the imaging control unit 1021 has a first interruption determination time (first timeout time a) and a second interruption determination time (second timeout time) corresponding to the radiography imaging unit 101 determined in step S401. b) is transmitted to the radiography imaging unit 101. Here, the imaging control unit 1021 may determine the first timeout time a and the second timeout time b from the image data display time that matches the determined image size of the imaging unit. For example, as shown in FIG. 9, the image size of the photographing unit A is 2800 (pixel) × 3408 (pixel), and the photographing control unit 1021 has an image data display time (reduced image data display time) corresponding to this image size. 8000 msec, total image data display time 33000 msec) is acquired from the table of FIG. 9A, and the first interruption determination time (first timeout time a) and the second interruption determination time (second timeout time) are obtained. As b), it can be transmitted to the radiography unit 101.

Next, in step S403, the reception control unit 1022 starts receiving the image data when the radiological imaging unit 101 starts transmitting the image data.

In step S404, the reception control unit 1022 starts measuring the elapsed time t2 from the start of receiving the image data. The reception control unit 1022 includes a measurement unit that measures the elapsed time from the start of reception, and the measurement unit measures the elapsed time from the start of receiving image data.

In step S405, the reception control unit 1022 determines whether or not the reception of the reduced image data is completed. If the reception of the reduced image data is completed (S405-Yes), the process proceeds to step S407. The reception control unit 1022 determines whether or not the reception of the reduced image data is completed, and when the reception of the reduced image data is completed, the display control unit 1023 causes the display device 30 to display the reduced image data. On the other hand, if the reception of the reduced image data is not completed (S405-No), the process proceeds to step S406.

In step S406, the reception control unit 1022 determines whether or not the reception of the reduced image data is completed, and when the reception of the reduced image data is not completed, the measured time and the first interruption determination time. By comparing with the time based on (first timeout time a + α: additional time that can be arbitrarily set), it is determined whether to continue receiving the reduced image data or to end the reception of the reduced image data. Here, the time based on the first interruption determination time is the time obtained by adding the settable additional time α to the first interruption determination time a. The reception control unit 1022 determines whether or not the elapsed time t2 exceeds the time based on the first interruption determination time (first timeout time a + additional time α). The first time-out time in the console 102 may be longer than the time-out time of the radio-imaging unit 101 in addition to the time set in the radio-imaging unit 101. In this example, the time obtained by adding the additional time (300 msec) to the first time-out time a notified to the radiography imaging unit 101 is defined as the first time-out time in the console 102.

When the elapsed time t2 exceeds the first timeout time (a + 300 msec) (S406-No), the process proceeds to step S414. On the other hand, if the elapsed time t2 does not exceed the first timeout time (a + 300 msec) in the determination of step S406 (S406-Yes), the process is returned to step S405, and the same process is executed in step S405. .. Then, when it is determined in step S405 that the reception of the reduced image data is completed (405-Yes), the process proceeds to step S407.

In step S407, the display control unit 1023 causes the display device 30 to display the reduced image data for which reception has been completed. Further, in step S408, the display control unit 1023 enables image editing on the reduced image data displayed on the display device 30. Here, FIG. 6 is a diagram showing a display example of reduced image data in the display device 30. For example, the display control unit 1023 displays the reduced image data on the display device 30 as shown in FIG. 6, and controls the display so as to enable image editing operations such as image cropping, image rotation, and image inversion. Do. The display control unit 1023 displays the image editing unit 601 for performing the image editing operation on the display screen of the display device 30, and based on the editing operation via the image editing unit 601, the image editing operation of the reduced image data. Is possible.

Next, in step S409, the reception control unit 1022 determines whether or not the reception of all image data is completed. If the reception of all image data is completed (S409-Yes), the process proceeds to step S411. On the other hand, if the reception of all image data is not completed (S409-No), the process proceeds to step S410.

In step S410, the reception control unit 1022 determines whether or not the reception of the generated radiation image data (all image data) is completed, and measures when the reception of the generated radiation image data is not completed. Whether to continue receiving the generated radiographic image data by comparing the time obtained with the time based on the second interruption determination time (second timeout time b + β: optional addition time). Alternatively, it is determined whether to end the reception of the generated radiographic image data. Here, the time based on the second interruption determination time is the time obtained by adding the settable additional time β to the second interruption determination time b. The reception control unit 1022 determines whether or not the elapsed time t2 exceeds the time based on the second interruption determination time (second timeout time b + addition time b). The second time-out time in the console 102 may be longer than the time-out time of the radio-imaging unit 101 in addition to the time set in the radio-imaging unit 101. In this example, the time obtained by adding the additional time (500 msec) to the second time-out time b notified to the radiography imaging unit 101 is defined as the second time-out time in the console 102.

When the elapsed time t2 exceeds the second timeout time (b + 500 msec) (S410-No), the process proceeds to step S414. On the other hand, if the elapsed time t2 does not exceed the second timeout time (b + 500 msec) in the determination of step S410 (S410-Yes), the process is returned to step S409, and the same process is executed in step S409. .. Then, when it is determined in step S409 that the reception of all the image data is completed (409-Yes), the process proceeds to step S411.

In step S411, the display control unit 1023 causes the display device 30 to display all the image data for which reception has been completed. In step S412, the reception control unit 1022 ends the measurement of the elapsed time t2. Then, in step S413, the reception control unit 1022 ends the image data reception process. The display control unit 1023 displays, for example, all the image data on the display device 30 as shown in FIG. 8, and controls the display so as to enable image editing operations such as image cropping, image rotation, and image inversion. Do. The display control unit 1023 displays the image editing unit 801 for performing the image editing operation on the display screen of the display device 30, and based on the editing operation via the image editing unit 801, the image editing operation of all the image data. Is possible.

On the other hand, in step S414, the reception control unit 1022 determines that the elapsed time has exceeded the timeout time in steps S406 and S410, so that the measurement of the elapsed time t2 is completed. Ends receiving.

In step S416, the reception control unit 1022 calculates the progress rate of image transfer indicating the rate at which the transfer is completed, based on the image size captured by the radiography photographing unit 101 and the image data for which the image transfer is completed. That is, the reception control unit 1022 calculates the progress rate (transfer progress rate) of the image transfer, which percentage of all the image data is received before the image transfer is interrupted.

Further, in step S417, the display control unit 1023 causes the display device 30 to display the image transfer progress rate (transfer progress rate) calculated in step S416 and a message notifying that the transfer has been interrupted. As shown in FIG. 7, the display control unit 1023 displays a retransfer instruction unit 701 that instructs the photographing unit to retransfer the image and an end instruction unit 702 that instructs the end of the image transfer in the display screen of the display device 30. The display makes it possible to select whether to execute the image retransfer or end the image transfer based on the operation via the retransfer instruction unit 701 or the end instruction unit 702.

The operation detection unit 1024 receives the input information by the operator input via the retransfer instruction unit 701 or the end instruction unit 702, and inputs the input information to the photographing control unit 1021. The imaging control unit 1021 controls the radiography imaging unit based on the information input from the operation detection unit 1024. When the re-transfer instruction is input, the imaging control unit 1021 requests the radio-imaging unit 101 to re-transfer the interrupted image data, and causes the radio-imaging unit to execute the re-transfer of the interrupted image data. When the image transfer end instruction is input, the shooting control unit 1021 ends the interrupted image transfer.

In step S418, the imaging control unit 1021 determines whether or not to retransfer the interrupted image data based on the information input from the operation detection unit 1024. When the end instruction of the image transfer is input (when the button of the end instruction unit 702 in FIG. 7 is pressed by the operator), that is, when the retransfer is not performed (S418-No), the process proceeds to step S413. Then, in step S413, the photographing control unit 1021 ends the transfer of the interrupted image.

On the other hand, in the determination in step S418, when the retransfer instruction is input (when the button of the retransfer instruction unit 701 in FIG. 7 is pressed by the operator), that is, when the retransfer is performed (S418-Yes). ), The process proceeds to step S419.

In step S419, the imaging control unit 1021 requests the radiography imaging unit 101 to retransfer the interrupted image data, and causes the radiography imaging unit to execute the retransfer of the interrupted image data. Then, the process is returned to step S403, and in step S403, the reception control unit 1022 starts receiving the image data transferred again from the radiography imaging unit 101. The above processing is the processing procedure of the console 102.

As described above, the same effect as that of the first embodiment can be obtained even in the configuration in which the image transfer timeout is executed by the console 102. That is, the timeout time from the start of image transfer to the display of reduced image data (first timeout time) is set short, and the timeout time from the start of image transfer to the display of all image data (second timeout time) is set. Set long. By setting the first timeout time and the second timeout time in this way, even in a situation where the communication path (communication environment) of the image transfer is unstable, the transfer can be completed quickly until the transfer of the reduced image data. After the transfer of the reduced image data is completed, it becomes possible to realize the radiography system 10 capable of reliably transferring all the image data even little by little (third embodiment).
Next, the configuration of the radiography system of the third embodiment will be described. In the radiography system of the present embodiment, the first interruption determination time (first timeout time a + c) and the second interruption determination time (first interruption determination time) are taken into consideration in consideration of the radiation accumulation time (c) in the radiation imaging unit 101. A configuration for setting the second timeout time b + c) and determining whether or not the image transfer has been interrupted will be described. The configuration of the radiography system of the third embodiment is the same as the configuration of the radiography system described in the first embodiment (FIG. 1).

FIG. 11 is a flowchart showing a processing procedure of the console 102 until the radiological imaging unit 101 used by the console 102 is specified, the radiological imaging is performed, and the radiological imaging is completed in the radiological imaging system 10 according to the third embodiment. Is.

First, in step S501, the imaging control unit 1021 of the console 102 determines the radiation imaging unit 101 to be used for imaging from a plurality of radiation imaging units (also simply referred to as “imaging unit”), and the imaging control unit 1021 determines Notify the determined radiography unit 101. FIG. 5 is a diagram showing a display example of the display device 30, and for example, on the screen displayed on the display device 30 as shown in FIG. 5, the state of the radiography unit used for radiography, patient information, and radiography conditions are displayed. It is displayed. A linked shooting unit is set for the shooting conditions. For example, in the display example of FIG. 5, the shooting unit A corresponds to the shooting condition 1 (shooting part: CHESTPA, time: 500 msec), and the shooting condition 5 (shooting part: CHESTPA, time: 600 msec) is set. The shooting unit B corresponds. The console 102 can determine the radiographic imaging unit 101 to be used for radiographic imaging based on the selection of imaging conditions input by the GUI or an external operating device. In the display example of FIG. 5, the shooting condition 1 is selected (selected), and the state display 501 of the shooting unit (in this case, the shooting unit A) used for shooting under the shooting condition 1 is “preparing for shooting”. Is displayed.

In step S502, the imaging control unit 1021 determines the radiation accumulation time c based on the imaging conditions. FIG. 12 is a diagram showing an example of a combination of imaging conditions and storage time, and the imaging control unit 1021 has a non-volatile storage unit that stores the table shown in FIG. For example, as shown in FIG. 12, a photographing unit, an imaging portion, an accumulation time, an imaging direction, and the like to be used are associated with the imaging conditions. The accumulation time corresponding to the photographing condition 1 selected in FIG. 5 is 500 msec. Therefore, the imaging control unit 1021 determines the radiation accumulation time c to be 500 msec.

In step S503, the imaging control unit 1021 sets the first timeout time a (= a + c) and the second timeout time b (= b + c) corresponding to the radiation imaging unit 101 determined in step S501 to the radiation imaging unit 101. Send to. Here, the shooting control unit 1021 may determine the first timeout time a and the second timeout time b from the image data display time that matches the determined image size of the shooting unit (FIG. 9). Then, the imaging control unit 1021 adds the time obtained by adding the radiation accumulation time c to the first time-out time a and the second time-out time b, the first time-out time a (= a + c), and the second time-out time b. Is acquired as the timeout time b (= b + c) of. For example, as shown in FIG. 9, the image size of the photographing unit A is 2800 (pixel) × 3408 (pixel), and the photographing control unit 1021 has an image data display time (reduced image data display time) corresponding to this image size. 8000 msec, total image data display time 33000 msec) is acquired from the table of FIG. 9 (a), the radiation accumulation time c is added to the acquired time, and the first interruption determination time (first timeout time a = (1). It is possible to transmit to the radiography unit 101 as a + c)) and the second interruption determination time (second timeout time b = (b + c)). The radiography unit 101 transfers the transfer based on the first interruption determination time (first timeout time a = (a + c)) and the second interruption determination time (second timeout time b = (b + c)). Control the transfer by determining whether to continue or interrupt the transfer. Specifically, in the flowcharts of FIGS. 3 and 4 showing the processing procedure of the radiography unit 101, in step S208 and step S305, the interruption determination time (first timeout time a = (a + c)) is used. Judgment processing is performed. Further, in step S211 and step S308, the determination process is performed based on the second interruption determination time (second timeout time b = (b + c)). That is, the first interruption determination time and the second interruption determination time are set based on the radiation accumulation time c in the radiation imaging unit 101 determined by the imaging conditions.

Next, in step S504, the reception control unit 1022 starts receiving the image data when the radiological imaging unit 101 starts transmitting the image data.

In step S505, the reception control unit 1022 determines whether or not the reception of the reduced image data is completed. If the reception of the reduced image data is completed (S505-Yes), the process proceeds to step S507. On the other hand, if the reception of the reduced image data is not completed (S505-No), the process proceeds to step S506.

In step S506, the reception control unit 1022 determines whether or not the radiography photographing unit 101 interrupts the image transfer. When the image transfer is interrupted in the radiography unit 101, the radiography unit 101 notifies the console 102 that the image transfer has been interrupted. The reception control unit 1022 can determine whether or not the radiography imaging unit 101 has interrupted the image transfer based on the notification transmitted from the radiography imaging unit 101. If the radiography unit 101 interrupts the image transfer (S506-Yes), the process proceeds to step S513. On the other hand, if the radiography unit 101 has not interrupted the image transfer (S506-No), the process is returned to step S505, and the same process is executed in step S505. Then, when it is determined in step S505 that the reception of the reduced image data is completed (S505-Yes), the process proceeds to step S507.

In step S507, the display control unit 1023 causes the display device 30 to display the reduced image data for which reception has been completed. Further, in step S508, the display control unit 1023 enables image editing on the reduced image data displayed on the display device 30. Here, FIG. 6 is a diagram showing a display example of reduced image data in the display device 30. For example, the display control unit 1023 displays the reduced image data on the display device 30 as shown in FIG. 6, and controls the display so as to enable image editing operations such as image cropping, image rotation, and image inversion. Do. The display control unit 1023 displays the image editing unit 601 for performing the image editing operation on the display screen of the display device 30, and based on the editing operation via the image editing unit 601, the image editing operation of the reduced image data. Is possible.

In the state where the reduced image data is displayed (FIG. 6), the shooting unit A has completed the transfer processing of the reduced image data, and the shooting unit A is in the state of transferring all the image data. The display control unit 1023 displays the status display 602 of the photographing unit A as "all image data is being transferred".

Next, in step S509, the reception control unit 1022 determines whether or not the reception of all image data is completed. If the reception of all image data is completed (S509-Yes), the process proceeds to step S511. On the other hand, if the reception of all image data is not completed (S509-No), the process proceeds to step S510.

In step S510, the reception control unit 1022 determines whether or not the radiography photographing unit 101 interrupts the image transfer. When the image transfer is interrupted in the radiography unit 101, the radiography unit 101 notifies the console 102 that the image transfer has been interrupted. The reception control unit 1022 can determine whether or not the radiography imaging unit 101 has interrupted the image transfer based on the notification transmitted from the radiography imaging unit 101. If the radiography unit 101 interrupts the image transfer (S510-Yes), the process proceeds to step S513. On the other hand, if the radiography unit 101 has not interrupted the image transfer (S510-No), the process is returned to step S509, and the same process is executed in step S509. Then, when it is determined in step S509 that the reception of all image data is completed (S509-Yes), the process proceeds to step S511.

In step S511, the display control unit 1023 causes the display device 30 to display all the image data for which reception has been completed, and in step S512, the reception control unit 1022 ends the image data reception process. When the transfer of image data is interrupted and an instruction to end the image transfer is input, the shooting control unit 1021 ends the transfer of the interrupted image in this step. Here, FIG. 8 is a diagram showing a display example of all image data in the display device 30. The display control unit 1023 displays, for example, all the image data on the display device 30 as shown in FIG. 8, and controls the display so as to enable image editing operations such as image cropping, image rotation, and image inversion. Do. The display control unit 1023 displays the image editing unit 801 for performing the image editing operation on the display screen of the display device 30, and based on the editing operation via the image editing unit 801, the image editing operation of all the image data. Is possible.

In the state where all the image data is displayed (FIG. 8), the transfer process of all the image data is completed in the photographing unit A, and in the display example of FIG. 8, the photographing condition 1 using the photographing unit A has been photographed. Is displayed as (802). Further, in the next shooting, the shooting condition 5 using the shooting unit B is displayed as selected (selected) (803). In FIG. 8, the state display 804 of the shooting unit (in this case, the shooting unit B) used for shooting under the shooting condition 5 is in a state of being displayed as “preparing for shooting”.

Next, in step S513, the reception control unit 1022 determines that the image transfer has been interrupted in step S506 or step S510, so that the image data reception process is interrupted.

In step S514, the reception control unit 1022 calculates the progress rate of image transfer indicating the rate at which the transfer is completed, based on the image size captured by the radiography photographing unit 101 and the image data for which the image transfer is completed. That is, the reception control unit 1022 calculates the progress rate (transfer progress rate) of the image transfer, which percentage of all the image data is received before the image transfer is interrupted. For example, as shown in FIG. 9, the image size taken by the photographing unit A is 2800 (pixel) × 3408 (pixel), and the reception control unit 1022 is an image with respect to this image size. It is possible to calculate the progress rate of image transfer (transfer progress rate) by acquiring the ratio of the image data for which the transfer has been completed. In this example, an example of the photographing unit A is shown, but the same applies even when another photographing unit shown in FIG. 9B is used.

Further, in step S515, the display control unit 1023 causes the display device 30 to display the image transfer progress rate (transfer progress rate) calculated in step S514 and a message notifying that the transfer has been interrupted. Here, FIG. 7 is a diagram showing a progress rate (transfer progress rate) of image transfer in the display device 30 and a display example of a message notifying that the transfer has been interrupted. In the state where the image data transfer is interrupted (FIG. 7), the status display 703 of the photographing unit (in this case, the photographing unit A) used for shooting is displayed as "image transfer interrupted". .. As shown in FIG. 7, the display control unit 1023 displays a retransfer instruction unit 701 that instructs the photographing unit to retransfer the image and an end instruction unit 702 that instructs the end of the image transfer in the display screen of the display device 30. The display makes it possible to select whether to execute the image retransfer or end the image transfer based on the operation via the retransfer instruction unit 701 or the end instruction unit 702.

The operation detection unit 1024 receives the input information by the operator input via the retransfer instruction unit 701 or the end instruction unit 702, and inputs the input information to the photographing control unit 1021. The imaging control unit 1021 controls the radiography imaging unit based on the information input from the operation detection unit 1024. When the re-transfer instruction is input, the imaging control unit 1021 requests the radio-imaging unit 101 to re-transfer the interrupted image data, and causes the radio-imaging unit to execute the re-transfer of the interrupted image data. When the image transfer end instruction is input, the shooting control unit 1021 ends the interrupted image transfer.

In step S516, the photographing control unit 1021 determines whether or not to retransfer the interrupted image data based on the information input from the operation detection unit 1024. When the end instruction of the image transfer is input (when the button of the end instruction unit 702 in FIG. 7 is pressed by the operator), that is, when the retransfer is not performed (S516-No), the process proceeds to step S512. Then, in step S512, the photographing control unit 1021 ends the transfer of the interrupted image.

On the other hand, in the determination in step S516, when the retransfer instruction is input (when the button of the retransfer instruction unit 701 in FIG. 7 is pressed by the operator), that is, when the retransfer is performed (S516-Yes). ), The process proceeds to step S517.

In step S517, the imaging control unit 1021 requests the radiography imaging unit 101 to retransfer the interrupted image data, and causes the radiography imaging unit to execute the retransfer of the interrupted image data. Then, the process is returned to step S504, and in step S504, the reception control unit 1022 starts receiving the image data transferred again from the radiography imaging unit 101. The above processing is the processing procedure of the console 102.

As described above, the processing time that affects the image transfer time, such as the radiation accumulation time, is added based on the imaging conditions, and the first timeout time and the second timeout time are changed based on the imaging conditions. By doing so, it is possible to adjust the timeout time to an appropriate value.

Add the radiation accumulation time, set the timeout time from the start of image transfer to the display of reduced image data (first timeout time a + c) short, and set the timeout time from the start of image transfer to the display of all image data. (Second timeout time b + c) is set long. By setting the first timeout time a + c and the second timeout time b + c in this way, even in a situation where the communication path (communication environment) of image transfer is unstable, transfer can be performed quickly until the transfer of reduced image data. After the completion of the transfer of the reduced image data, it becomes possible to realize the radiography system 10 capable of reliably transferring all the image data even little by little.
