<P>PROBLEM TO BE SOLVED: To provide a radiographic apparatus in which imaging of a soft tissue is prevented from being inhibited due to an unwrapping error. <P>SOLUTION: An X-ray image detector detects an X-ray which is emitted from an X-ray source and passes through first and second gratings, and generate image data. A phase-differential image generating section generates a phase-differential image on the basis of the image data. An OK/NG region detecting section detects an NG region where an unwrapping error easily occurs in the phase-differential image, and detects the other regions as OK regions. An unwrapping processing section sets a starting point SP in an OK region, applies unwrapping processing to adjacent pixels while using the starting point SP as a reference point, and then, sequentially performs unwrapping processing for the pixels in the OK regions while changing the reference point for the pixels subjected to the unwrapping processing. <P>COPYRIGHT: (C)2013,JPO&INPIT |
