Abstract
An X-ray phase contrast imaging device of the present invention can change an arrangement pitch of slits related to a multi-slit and an arrangement pitch of phase shift sections related to a phase grating. A positional relationship among the multi-slit 3b, the phase grating, and an FPD is determined based on the arrangement pitch of the slits related to the multi-slit, the arrangement pitch of the phase shift sections related to the phase grating, and an arrangement pitch of detection elements related to the FPD. Among these arrangement pitches, by changing the arrangement pitch of the slits and the arrangement pitch of the phase shift sections, the present invention can change the positional relationship among the multi-slit, the phase grating, and the FPD.
