Low-dose simulation for grating-based X-ray dark-field radiography using a virtually decreased irradiation area
Abstract
Virtually reducing the irradiation area is a simple approach to generate low-dose radiographs based on images acquired with scanning-based dark-field radiography. However, as the algorithm creates stripe artifacts in the dark-field images, particularly at very low dose levels, that are not present in measured low-dose images, simulated images have reduced image quality compared to their measured counterparts.
