Abstract

In order to provide a large-area radiation imaging apparatus that has an energy resolution while suppressing the occurrence of an artifact, the radiation imaging apparatus includes a detector and a signal processing unit. The detector includes a plurality of pixels for acquiring a pixel value in accordance with incident radiation. The signal processing unit performs signal processing for estimating energy of a radiation quantum of the incident radiation at a predetermined pixel included in the pixels using the amount of change in the pixel value of the predetermined pixel.
