Radiation imaging apparatus, driving method for the same, and non-transitory computer-readable medium

A driving method for a radiation imaging apparatus including a plurality of sensors, each of the plurality of sensors including a detection element configured to detect radiation, a sampling unit configured to sample a signal from the detection element, and a reset unit configured to initialize the detection element, the method comprising:

• performing a first reset operation of causing the reset units to initialize the detection elements before the start of first radiation irradiation onto the plurality of sensors;
• performing a first sampling operation of causing the sampling units to sample signals from the detection elements in accordance with the first irradiation;
• performing a first output operation of outputting the signals sampled in the performing the first sampling operation;
• performing a second reset operation of causing the reset units to initialize the detection elements before the start of second irradiation next to the first irradiation;
• performing a second sampling operation of causing the sampling units to sample signals from the detection elements in accordance with the second irradiation;
• and
• performing a second output operation of outputting the signals sampled in the performing the second sampling operation,
• wherein the performing the first output operation is started after completion of the second reset operation and before the second sampling operation.

A radiation imaging apparatus comprising a plurality of sensors and a driving unit configured to drive the plurality of sensors, the plurality of sensors, respectively, including a plurality of detection elements each configured to detect radiation, a plurality of sampling units each configured to sample a signal from the respective detection element, and a plurality of reset units each configured to initialize the respective detection element, wherein the driving unit performs:

• a first reset operation of causing the plurality of reset units to collectively initialize the plurality of detection elements;
• a first sampling operation of causing the plurality of sampling units to collectively sample signals from the plurality of detection elements in accordance with first radiation irradiation started after the first reset operation;
• a first output operation of outputting the signals sampled in the first sampling operation, sequentially;
• a second reset operation of causing the plurality of reset units to collectively initialize the plurality of detection elements after the first sampling operation;
• a second sampling operation of causing the plurality of sampling units to collectively sample signals from the plurality of detection elements in accordance with second irradiation started after the second reset operation following the first irradiation;
• and
• a second output operation of outputting the signals sampled in the second sampling operation, sequentially, and
• wherein the driving unit is configured to operate in at least a mode in which the driving unit starts the first output operation after completion of the second reset operation and before the second sampling operation.
