ABSTRACT:
A focus-detector arrangement of an X-ray apparatus is disclosed, for generating projective or tomographic phase contrast recordings of a subject. In at least one embodiment, least one grating of a focus-detector arrangement includes, at least partially, a macroscopically homogeneous medium which, when excited by an energy source, assumes a periodic structure/standing wave field that leads to beam splitting and the formation of an interference pattern when the X-ray beam passes through.
