Abstract: A phantom body (PB) for use in a differential phase contrast imaging apparatus (IM) for calibration of same. The phantom body (PB) allows for simultaneous calibration of three different image signal channels, namely refraction, phase shift and small angle scattering.

Abstract: An X-ray imaging apparatus with an interferometer (IF) and an X-ray detector (D). A footprint of the X-ray detector (D) is larger than a footprint of the interferometer (IF). The interferometer is moved in scan motion across the detector (D) whilst the detector (D) remains stationary. Preferably the detector is a 2D full field detector.

Abstract: A grating based interferometric X-ray imaging apparatus having an interferometer (IF). The interferometer comprises at least one grating (G1). The grating (G1) is tiltable relative to an optical axis of the X-ray imaging apparatus. This allows changing a design energy of the X-ray imaging apparatus.
