  • Publication number: 20230420465
    Abstract: An X-ray detection device includes a capillary, an X-ray detection element, and a detection circuit. The capillary has a plurality of X-ray passing regions. The X-ray detection element has a conversion portion and a plurality of pixel electrode portions. The conversion portion faces the capillary and absorbs X-rays to generate carriers. The detection circuit detects carriers collected from the conversion portion through the plurality of pixel electrode portions. When a plurality of carriers generated by incidence of an X-ray are dispersed and collected in two or more of the pixel electrode portions, the detection circuit determines one of the pixel electrode portions corresponding to an X-ray incidence position and corrects and evaluates an amount of carriers in the one of the pixel electrode portions or ignores the incidence of the X-ray.
