Radiation imaging system, radiation imaging apparatus, radiation imaging method, and storage medium

1. A radiation imaging system, comprising:

a console; and

an imaging unit; and;

said imaging unit being configured to transfer to said console a radiation image, said radiation image having been generated based on received radiation;

said console being configured to set a first interrupt determination time for determining an interrupt of transfer of reduced image data of the radiation image; and

said radiation imaging system being configured to interrupt the transfer of the reduced image data when an elapsed time taken to transfer the reduced image exceeds the first interrupt determination time, wherein

whole image data of the radiation image data is transferred when the transfer of the reduced image data is complete within an elapse of the first interrupt determination time.

2. The system according to claim 1 , wherein the console is configured to set a second interrupt determination time for determining an interrupt of transfer of whole image data of the radiation image data.

3. The system according to claim 1 , wherein after completion of transfer of reduced image data obtained by reducing image size of the generated radiation image, the imaging unit transfers the generated radiation image.

4. The system according to claim 2 , wherein the radiation imaging system includes a measurement unit configured to measure an elapsed time taken to transfer the radiation image,

the radiation imaging system determines whether to continue or interrupt to transfer the reduced image data based on comparison between the measured time and the first interrupt determination time if the transfer of the reduced image data is not complete, and

the radiation imaging system determines whether to continue or interrupt to transfer the whole image data based on comparison between the measured time and the second interrupt determination time if the transfer of the whole image data is not complete.

5. The system according to claim 2 , wherein the radiation imaging system determines to continue to transfer the reduced image data if the measured time does not exceed the first interrupt determination time, and

the radiation imaging system determines to continue to transfer the whole image data if the measured time does not exceed the second interrupt determination time.

6. The system according to claim 4 , wherein if the transfer is interrupted, the radiation imaging system outputs a notification indicating an interrupt of image transfer.

7. The system according to claim 6 , further comprising a display control unit configured to display the notification on a display unit.

8. The system according to claim 7 , wherein the display control unit displays on a display screen of the display unit a retransfer instruction unit configured to instruct to retransfer image data for which the image transfer has been interrupted and an end instruction unit configured to instruct to end the image transfer.

9. The system according to claim 8 , wherein the radiation imaging system performs transfer control to restart the interrupted transfer when retransfer of the image data is instructed from the retransfer instruction unit.

10. The system according to claim 9 , wherein the radiation imaging system performs transfer control to transfer untransferred image data from the interrupted pixel based on pixel information indicating an interrupted pixel in image data when retransfer of the image data is instructed from the retransfer instruction unit.

11. The system according to claim 9 , wherein the radiation imaging system performs transfer control to transfer image data at the start of transfer from the beginning when retransfer of the image is instructed from the retransfer instruction unit.

12. The system according to claim 2 , wherein the second interrupt determination time is a time longer than the first interrupt determination time.

13. The system according to claim 8 , wherein the first interrupt determination time is a time taken to display the reduced image data on the display unit, and the second interrupt determination time is a time taken to display the whole image data on the display unit.

14. The system according to claim 1 , further comprising a reception control unit configured to receive the transferred image, wherein

the reception control unit calculates progress of the image transfer indicating a percentage of completion of the transfer based on an image size captured by the imaging unit and image data for which image transfer is complete.

15. The system according to claim 13 , wherein a time based on the first interrupt determination time is a time obtained by adding a settable additional time to the first interrupt determination time, and a time based on the second interrupt determination time is a time obtained by adding a settable additional time to the second interrupt determination time.

16. The system according to claim 2 , wherein the first interrupt determination time and the second interrupt determination time are set based on an accumulation time of radiation in the imaging unit, which is decided based on an imaging condition.

17. A radiation imaging method comprising:

transferring a radiation image generated based on received radiation to a console;

setting a first interrupt determination time for determining an interrupt of transfer of reduced image data of the radiation image;

interrupting the transfer of the reduced image data in a case where an elapsed time taken to transfer the reduced image exceeds the first interrupt determination time; and

transferring whole image data of the radiation image data in a case where the transfer of the reduced image data is complete within an elapse of the first interrupt determination time.

18. A computer-readable storage medium storing a program that causes a computer to execute each step of a radiation imaging method, the method comprising:

transferring a radiation image generated based on received radiation to a console;

setting a first interrupt determination time for determining an interrupt of transfer of reduced image data of the radiation image;

interrupting the transfer of the reduced image data in a case where an elapsed time taken to transfer the reduced image exceeds the first interrupt determination time; and

transferring whole image data of the radiation image data in a case where the transfer of the reduced image data is complete within an elapse of the first interrupt determination time.
