Abstract
A radiation image sensing apparatus is provided. The apparatus comprises an image sensing area where conversion elements are arranged and used in an image sensing operation of acquiring a radiation image, a detection element configured to detect a radiation dose of radiation entering the image sensing area, a readout unit and a controller. The controller corrects a detection signal read out from the detection element by the readout unit during incidence of radiation in a second image sensing operation performed next to a first image sensing operation, based on a correction amount acquired based on a correction signal read out from the detection element by the readout unit after an end of the incidence of the radiation in the first image sensing operation, and detects a dose of incident radiation in the second image sensing operation based on the corrected detection signal.
