Original Abstract Submitted
A radiation imaging apparatus includes a pixel array having a plurality of pixels configured to detect radiation, and a controller configured to obtain a radiation generation condition related to a radiation generating apparatus during fluoroscopic imaging, and determine, during the fluoroscopic imaging, timings of a plurality of sampling and holding operations in each of the plurality of pixels in accordance with the radiation generation condition. The timing of at least one sampling and holding operation is a timing in an irradiation period of radiation, and each of the plurality of pixels includes a conversion element configured to convert radiation into an electrical signal, and a sample and hold circuit configured to sample and hold signals from the conversion element multiple times in accordance with the timings, determined by the controller, of the plurality of sampling and holding operations.
