摘要：

In this work, we investigate sources to the dark-field signal in a grating-based differential phase contrast image setup other than scattering. Specifically, the effect of aliasing, detector crosstalk, non-constant phase gradients, and the partial volume effect are evaluated. All these effects are able to create a dark-field signal.
