PROBLEM TO BE SOLVED: To provide a mobile collimator by a simple mechanism in a radiation phase difference imaging apparatus.SOLUTION: The radiation phase difference imaging apparatus according to the present invention is configured to integrate a collimator C with a multi-slit S. This configuration can simplify the apparatus configuration further than a case where the apparatus includes the collimator C independently from the multi-slit S. Further, even when the multi-slit S is configured to move, the configuration causes no trouble in imaging. Consequently, the radiation phase difference imaging apparatus according to the present invention can achieve the mobile collimator by a simple configuration.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT
