Title:
Quantitative wave-optical numerical analysis of the dark-field signal in grating-based X-ray interferometry 
Abstract:
Here we report a full wave-optical numerical simulation framework that quantitatively predicts the outcome of grating-based X-ray dark-field imaging experiments on an ensemble of sub-pixel spherical scatterers. We particularly show how the behavior of the dark-field imaging signal differs from and complements the conventional X-ray transmission imaging signal when certain sample parameters, such as the size, number, and total volume of sub-pixel spherical substructures are changed and compare ou...    »
