Abstract

An X-ray imaging system includes: a micro X-ray source array formation part configured to form a micro X-ray source array by partially shielding an X-ray emitted from an X-ray source; and an X-ray detector configured to detect an X-ray transmitted through a test object. The micro X-ray source array formation part includes a plurality of gratings disposed between the X-ray source and the X-ray detector. A ratio of X-rays transmitted through all of the plurality of gratings to X-rays generated from the X-ray source varies depending on a position of an X-ray generating point on the X-ray source, and the micro X-ray source array formation part forms a micro X-ray source array of a pattern in accordance with the variation of the ratio of the transmitted X-rays.
