Arrangement and method for the projective and / or tomographic phase contrast imaging with X-rays

The invention relates to an arrangement and method for the projective and / or tomographic phase contrast imaging with X-rays, wherein one or more phase grating (G1) is arranged in the beam path in such a way / are that during one revolution of the at least one X-ray source (B), the examination subject (P) with different spatial orientations of the grating lines relative to the examination object (P) is scanned, so that from the two scans with differently oriented phase gratings (G1) can be each x-ray beam of the full refraction and thus the complete Phasenschubgradient determined by the phase shift of an examination subject (P) projection as or to show in tomographic representation.
