X-ray interferometric imaging system
TL;DR: In this paper, an x-ray interferometric imaging system with a beam-splitting grating and a phase-shifting analyzer was presented. But the system was not designed for the use of the beamforming grating, and the beam splitting grating was placed in front of the detector.

Medical phase contrast x-ray imaging: current status and future prospects.
TL;DR: The exploitation of phase contrast appears to offer the tantalising possibility of creating the biggest change in medical x-ray imaging since the invention of computed tomography, but unfortunately the application of these ideas in a clinical context requires that technology be pushed to its limits in a number of areas includingx-ray sources, optics and detectors.
