Patent ID: 6934409

Claim:
A phase contrast radiographic image processing apparatus comprising: a radiation generation source; at least one radiation detector to capture a phase contrast radiographic image of an object, wherein a distance between the radiation generation source and the at least one radiation detector equals R 1 +R 2 , where R 1 is defined to be a distance between the radiation generation source and the object to be radiographed, and satisfying the formula: 10>R 1 ≧(D−7)/200 (in meters), where D is a focal spot size of the ray generated from the radiation generation source (in μm), and R 2 is defined to be a distance between the object to be radiographed and the at least one radiation detector and satisfying the formula: R 2 ≧0.15 (in meters), so that the size of the phase contrast radiographic image is larger than the object by a magnification factor of 1+R 2 /R 1 ; a management information storing section to store management information regarding a radiography; and an image processing section to apply an image processing onto a captured phase contrast radiographic image, wherein the image processing section determines an image processing condition based on the management information stored in the management information storing section and conducts the image processing based on the determined image processing condition.
