Abstract
A method of manufacturing an X-ray detector includes: applying a mask having an opening on a substrate on which a plurality of charge detection units are positioned; filling the opening with a paste including a photoelectric conversion material that absorbs X-rays to generate charges; and forming a photoconductive layer from the paste by separating the mask from the substrate. A thickness of the paste within the opening is thicker in an area adjacent to at least one edge among edges of the opening than in areas around other edges.
Claims12
An X-ray detector comprising:
- an X-ray detection unit including a photoconductive layer configured to receive X-rays and generate charges, a plurality of charge detection units on a substrate, the plurality of charge detection units configured to detect the generated charges, and an electrode on the photoconductive layer;
- and
- a housing configured to hold the X-ray detection unit such that a distance between a chest wall of the housing configured to butt against a trunk of a patient and an edge of the photoconductive layer adjacent to the chest wall is 2 mm or less.
A method of manufacturing an X-ray detector, comprising:
- applying a mask on a substrate such that the mask has a plurality of edges that define an opening therein, the substrate having a plurality of charge detection units positioned thereon;
- filling the opening with a paste such that a thickness of the paste filled in the opening is thicker in an area adjacent to at least one of the edges than in areas around other ones of the edges, the paste including a photoelectric conversion material configured to absorbs X-rays to generate charges;
- and
- forming a photoconductive layer from the paste by separating the mask from the substrate.
