<P>PROBLEM TO BE SOLVED: To perform calibration appropriate for magnification radiography at each magnification ratio in a radiation phase image radiographic apparatus that performs magnification radiography at various magnification ratios. <P>SOLUTION: The apparatus includes a magnification ratio obtainment unit 62 that receives an input of a magnification ratio in magnification radiography to obtain the magnification ratio, a calibration data obtainment unit 63 that obtains calibration data corresponding to the magnification ratio, and which are based on a second periodic pattern image detected by a radiation image detector without placing a subject, and a phase contrast image generation unit 61 that generates a phase contrast image based on the calibration data obtained by the calibration data obtainment unit and the second periodic pattern image detected by the radiation image detector with the subject placed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
