Abstract

Claims (23)

1. A radiation imaging system comprising:

a radiation imaging apparatus configured to generate a radiation image based on radiation emitted from a radiation generation apparatus; and

a control apparatus configured to acquire information from the radiation imaging apparatus and the radiation generation apparatus,

wherein the control apparatus includes:

at least one computer-readable storage media; and

at least one processor that is in communication with the at least one computer-readable storage media and that cooperate with the at least one computer-readable storage media to cause the control apparatus to:

determine whether the radiation image acquired from the radiation imaging apparatus is a failed image,

acquire irradiation information from the radiation generation apparatus, and

determine a factor in acquisition of the failed image, based on a determination result and the irradiation information.

2. The radiation imaging system according to claim 1 , wherein the failed image is a dark image with an insufficient dose of radiation to the radiation imaging apparatus.

3. The radiation imaging system according to claim 1 , wherein the control apparatus further includes a display device configured to display a factor in transfer of the failed image, based on a determination result.

4. The radiation imaging system according to claim 1 , wherein information about a radiation dose value is acquired.

5. The radiation imaging system according to claim 1 , wherein a radiation dose value null is assigned, in a case where the irradiation information is not acquired from the radiation generation apparatus.

6. The radiation imaging system according to claim 1 ,

wherein the radiation imaging apparatus generates the radiation image in synchronization with the emission of radiation by the radiation generation apparatus, and

wherein success or failure of the synchronization between the radiation generation apparatus and the radiation imaging apparatus is determined.

7. The radiation imaging system according to claim 6 ,

wherein the radiation imaging apparatus performs synchronous communication for generating the radiation image in synchronization with the emission of radiation by the radiation generation apparatus, with the radiation generation apparatus, and

wherein success or failure of the synchronization between the radiation generation apparatus and the radiation imaging apparatus is determined, based on information indicating whether the synchronous communication is completed within a predetermined time.

8. The radiation imaging system according to claim 1 ,

wherein the radiation imaging apparatus transmits a signal indicating an instruction to stop radiation to the radiation generation apparatus, based on a pixel value of a target region set in the radiation imaging apparatus, and a stop condition setting, and

wherein, based on a dose index calculated in the target region of the radiation image acquired from the radiation imaging apparatus, whether the radiation image is the failed image is determined.

9. The radiation imaging system according to claim 1 , wherein the control apparatus determines that there is a possibility that the radiation imaging system is not normally operating, based on a determination result indicating that the radiation image is not the failed image is determined, and the irradiation information acquired.
