<P>PROBLEM TO BE SOLVED: To provide a radiographic apparatus and a radiographic system which sufficiently suppress relative position deviation of first and second lattices on a temperature change and enable to photograph a suitable phase contrast image. <P>SOLUTION: The radiographic system includes two lattices that are a first lattice 31 and a second lattice 32 with a period substantially matching a pattern period of a radiation image formed by radiation passed through the first lattice 31, a radiation image detector 30 to detect a radiation image masked by the second lattice 32, and two support members 140, 150 to respectively support the first and the second lattices 31, 32. Two support members 140, 150 respectively have an almost equal amount of linear expansion. <P>COPYRIGHT: (C)2012,JPO&INPIT |
