<P>PROBLEM TO BE SOLVED: To provide an X-ray radiography apparatus for obtaining appropriate moire images by preventing displacement of fringe-scanning related parts (a multi-grid, a first grid and a second grid and the like) which require position adjustment of high precision, and an X-ray image system using the same. <P>SOLUTION: The X-ray radiography apparatus 1 performs photographing while relatively moving at least one of the first grid 14 and the second grid 15 in the direction orthogonal to the radiation direction of an X-ray with respect to the first grid 14 or the second grid 15 and obtains a plurality of moire images at fixed period intervals. An X-ray source 11, the first grid 14, the second grid 15, a subject table 13, and an X-ray detector 16 are placed along a gravity direction. A movement part is constituted only of moving elements moving in the direction orthogonal to the gravity direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
