Claim One:
1. An arrangement for at least one of projective and tomographic phase-contrast imaging using X-ray radiation, comprising: at least one coherent or quasi-coherent X-ray source to generate a beam path; a measurement field in which an examination object is positionable; a one-dimensional phase grid with grid lines to generate an interference pattern, positioned in the beam path; and a readout arrangement for the generated interference pattern, arranged downstream of the phase grid, to detect a change in the frequency pattern during a phase scan, the at least one X-ray source with the associated phase grid and the readout arrangement being designed, relative to the examination object, to rotate about a system axis, and the at least one phase grid is arranged in the beam path such that, during a rotation of the at least one X-ray source, the examination object is scanned with different spatial orientations of the grid lines relative to the examination object.
