Sketch of the experimental gbPC-CT setup.
From left to right: the rotating anode X-ray source followed by the source grating. The next element in the beam is the water container and the sample stage for tomography. Directly behind the sample is the phase grating. The analyser grating and the Pilatus II detector are installed at a discrete distance behind the phase grating. Figure adapted from Willner et al.43.
