Abstract
A radiation imaging apparatus comprising an imaging region where conversion elements used for an imaging operation of obtaining a radiation image corresponding to incident radiation are arranged, detecting portions in each of which a detecting element used to detect a radiation dose entering the imaging region is arranged, and a controller is provided. The controller is configured to perform, before the imaging operation, an offset readout operation of reading out offset signals of the detecting elements from the detecting portions, detect, in the imaging operation, the radiation dose entering the imaging region by using signals output from the detecting elements during irradiation with radiation and the offset signals, and be capable of changing, during a period of the offset readout operation, an order of reading out the offset signals from the detecting portions.
