X-ray detection device

An X-ray detection device, comprising:

• at least one capillary having a first surface, a second surface facing away from the first surface, a plurality of X-ray passing regions, and an X-ray shielding region, the plurality of X-ray passing regions penetrating from the first surface to the second surface and the X-ray shielding region being arranged between the plurality of X-ray passing regions;
• at least one X-ray detection element having a conversion portion and a plurality of pixel electrode portions, the conversion portion having a third surface facing the second surface of the capillary and a fourth surface facing away from the third surface, the conversion portion absorbing X-ray to generate carriers, and the plurality of pixel electrode portions being arranged in a two-dimensional manner on the fourth surface;
• and
• a detection circuit for detecting carriers collected from the conversion portion through the plurality of pixel electrode portions,
• wherein an inner diameter of each of the X-ray passing regions when viewed from an X-ray incidence direction is smaller than a width of each of the pixel electrode portions in an arrangement direction when viewed from the same direction, and
• 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 pixel electrode portion corresponding to an X-ray incidence position among the plurality of pixel electrode portions and corrects and evaluates an amount of carriers in the one pixel electrode portion or ignores the incidence of the X-ray.
