Abstract
A flat panel detector has an imaging area, in which pixels are arrayed in a matrix and signal lines for reading out electric signals from the pixels are provided, to detect an image of a subject from x-rays which are incident on the imaging area after penetrating the subject. Detective elements are arranged in the imaging area, to output electric signals corresponding to incident x-rays. Based on previously stored sensitivity data on the detective elements, high-sensitivity elements are selected from among the detective elements. The start of radiation and the end of radiation of x-rays toward the imaging area are detected by monitoring the electric signals from the selected high-sensitivity elements, to control operation of the imaging device on the basis of the detected start and end of radiation.
