摘要： A radiation imaging apparatus includes a pixel array having a plurality of pixels configured to detect radiation, a detector configured to detect radiation irradiation, and a controller. In a case in which a measured value obtained by using the detector exceeds a threshold in one range out of a positive range and a negative range with respect to a reference value, the controller controls a radiation image capturing operation by determining that the radiation irradiation has started. The controller changes the threshold in accordance with the measured value of the other range out of the positive range and the negative range.

摘要： A radiation imaging apparatus includes a pixel array including pixels for detecting radiation and column signal lines, a detector for detecting signals that appear in the column signal lines, and a controller. Each pixel includes a conversion element for converting radiation into an electrical signal and a switch for connecting the conversion element and a column signal line. In a state in which the switches of the pixels irradiated with radiation are open, the detector detects, as a radiation signal, a signal appearing in at least one column signal line. The controller converts an integrated value of the radiation signal into an integrated irradiation amount of radiation. The controller determines, based on the radiation signal and a signal read out by the detector from at least one pixel in a state in which the switch of the at least one pixel of the pixels is closed, a conversion coefficient to convert the integrated value into the integrated irradiation amount.
