Abstract
A radiation imaging apparatus, including a radiation or fluorescence detecting device on which a plurality of imaging elements are arranged in a form of a plane, having a sensor element, arranged on the imaging element, to detect radiation or fluorescence converted from the radiation which have passed through a subject, and to form radiation intensity signals, and a switching element, arranged on the imaging element, to perform switching of read-out of signals that show the intensity of radiation outputted from the sensor element; and a correcting device for correcting the radiation intensity signals, based on an angle of incidence of the radiation to the sensor element.
