Abstract:
1. A radiation image formation system comprising; a radiation image radiographing apparatus radiographing a phase contrast radiation image magnified by a radiation image detector for detecting radiation which transmits through a subject located apart from the radiation image detector; an image process apparatus for generating image data from the radiation image radiographed by the radiation image radiographing apparatus; an image output apparatus for outputting the image data input from the image process apparatus; and a magnified radiography setting unit for setting a magnifying rate M which satisfies: where the input pixel size A is a size of pixels composing the radiation image detected by the radiation image detector, and the minimum output pixel size B is a minimum size of pixels composing the image data output by the image output apparatus, wherein the radiation image radiographing apparatus radiographs the radiation image at the magnifying rate M; and the image process apparatus reduces the radiation image at a reducing rate 1/M.
