Designing the phase grating for Talbot-Lau phase-contrast imaging systems: a simulation and experiment study

, 2016
The performance of a Talbot-Lau interferometer depends to a great extent on its visibility. This means, to obtain high quality phase-contrast and dark-field images a high visibility is mandatory.

Simulation framework for coherent and incoherent X-ray imaging and its application in Talbot-Lau dark-field imaging

, 2015
A simulation framework for coherent X-ray imaging, based on scalar diffraction theory, is presented. It contains a core C++ library and an additional Python interface. A workflow is presented to include contributions of inelastic scattering obtained with
