Is high sensitivity always desirable for a grating-based differential phase contrast imaging system?

PURPOSE: In grating-based x-ray differential phase contrast (DPC) imaging, the measured signal amplitude of the phase shift induced by an image object is proportional to the so-called system sensitivity. Therefore, to achieve a better signal-to-noise (SNR) for improved imaging performance, it is gen...
