An arrangement for inverse x-ray phase contrast imaging includes a photon-counting x-ray detector and a multibeam x-ray tube. Focal points of the x-ray tube are collimated such that a narrow x-ray beam that is directed toward an optical axis of the arrangement and toward the x-ray detector may be generated. An active surface of the x-ray detector is at least as large as a cross-sectional surface of the narrow x-ray beam. The arrangement also includes a source grating arranged between the x-ray tube and the x-ray detector. The arrangement includes a defraction grating arranged between the source grating and the x-ray detector, and an absorption grating arranged between the defraction grating and the x-ray detector.
