Abstract:
1. A radiation imaging apparatus capable of taking a moving picture by acquiring a plurality of radiation image signals on the basis of a plurality of times of irradiation with radiation rays, the radiation imaging apparatus comprising: a radiation detector having a two-dimensional array of pixels, the radiation detector being configured to detect electric signals based on incident radiation rays; a reading circuit configured to read the electric signals; an analog-to-digital converter configured to convert the electric signals read by the reading circuit into digital signals; and a controller configured to switch an operation status of the analog-to-digital converter so that power consumption of the analog-to-digital-converter is reduced in a period between a start of an n-th time of irradiation with radiation rays and a start of an (n+1)-th time of irradiation with radiation rays, where n is a natural number.
