Abstract
The radiation imaging apparatus is provided that includes a radiation detector including a pixel array in which a plurality of pixels being capable of detecting radiation as electric signals are arranged, the radiation transmitted through an AEC sensor used for performing automatic exposure control of radiation irradiated from a radiation generating apparatus, a notifying unit for performing threshold value reached notification to the radiation generating apparatus, if a dose value of the radiation incident on the pixel array reaches a threshold value, and a threshold value setting unit for setting the threshold value in second radiation imaging in which automatic exposure control of the radiation by the radiation detector is performed after first radiation imaging in which the automatic exposure control of the radiation by the AEC sensor is performed, based on pixel values related to the electric signals detected by the plurality of pixels in the first radiation imaging
