摘要

We investigate the influence of the grating profiles on the image quality in grating-based x-ray phase-contrast imaging. The investigations are founded on an analytical description of contrast generation using Fourier decomposition. The imaging performance is quantified in terms of the visibility of the measured interferometer signal. We assess the impact of the duty cycle, height, shape and geometry of the grating profiles on the image quality. The analytical findings are compared with experimental and simulation results of previous publications.
