Abstract
An X-ray imaging system is provided with an X-ray source (), first and second absorption gratings (), and a flat panel detector (FPD) (), and obtains a phase contrast image of an object H by performing imaging while moving the second absorption grating () in x direction relative to the first absorption grating (). The following mathematical expression is satisfied where p' denotes a period of a first pattern image at a position of the second absorption grating (), and p′ denotes a substantial grating pitch of the second absorption grating (), and Ddenotes a dimension, in the x-direction, of an X-ray imaging area of each pixel of the FPD (). Here, 'n' denotes a positive integer.×(′)/|′|
