Abstract
A radiation imaging apparatus includes an imaging unit and an imaging control unit. The imaging control unit causes a switch unit, an accumulation unit, a removal unit, a holding unit, and an addition unit, which constitute a pixel circuit of the imaging unit, to operate at a timing before an imaging operation by the imaging unit so as to fix unstable voltages of the accumulation unit, the removal unit, the holding unit, and the addition unit to a predetermined voltage of a power supply connected via a switch unit.
