Abstract
A radiographic system which detects a radiation image transmitted through a subject with a radiation image detector and generates a phase contrast image of the subject, includes: a calculation section that calculates a distribution of refraction angles of radiation incident on the radiation image detector and generates the phase contrast image on the basis of the distribution of refraction angles; and a storage section that stores a correction coefficient of each pixel for making sensitivities of pixels equal. The calculation section performs sensitivity correction on a refraction angle of radiation incident on each pixel of the radiation image detector, which is calculated by imaging the subject, using the correction coefficient of the pixel stored in the storage section and generates the phase contrast image of the subject on the basis of the distribution of corrected refraction angles.
