Retrieval of multiple fibre orientations using X-ray dark-field signal modelling

Lorenzo Massimi, Michela Fratini, Shashidhara Marathe +4

Dark-field imaging is widely used to infer fibre orientation from signal modulation as a function of sample orientation. However, current X-ray dark-field retrieval methods are res…
