Abstract

A focus/detector system of an X-ray apparatus is disclosed, for generating projective or tomographic phase contrast recordings. The system, in at least one embodiment, includes at least of a beam source, having a focus and a focus-side source grating, arranged in the beam path and to generate a field of ray-wise coherent X-rays, and a detector arrangement having a multiplicity of grating/detector modules arranged next to one another. The detector arrangement, in at least one embodiment, which respectively include, arranged successively in the beam direction, at least one phase grating for generating a first interference pattern, an analysis grating for generating a further interference pattern, and detector elements arranged flat. The individual grating lines of all gratings are aligned mutually parallel.
