Abstract

A focus/detector system of an X-ray apparatus is disclosed for generating projective or tomographic phase contrast recordings. In at least one embodiment, the system includes a beam source, including a focus and a focus-side source grating, arranged in the beam path to generate a field of ray-wise coherent X-rays; and a grating/detector arrangement having a phase grating with grating lines arranged parallel to the source grating for generating an interference pattern and a detector having a multiplicity of detector elements arranged flat for measuring the radiation intensity behind the phase grating. Further, the detector elements are formed by a multiplicity of elongate detection strips, which are aligned parallel to the grating lines of the phase grating. Furthermore, at least one embodiment also relates to the use of this focus/detector system in an X-ray system for generating projective recordings or in C-arc equipment or a CT system, and/or to a method for generating projective and tomographic X-ray recordings of a subject.
