摘要:
A phase contrast X-ray imaging system includes an X-ray source; a plurality of gratings; a detector; a grating movement mechanism; and an image processor that generates a phase contrast image. The image processor generates the phase contrast image by using a pitch of an intensity change and a function which has the pitch as a variable and expresses the intensity change in a pixel value as a grating moves.
