Complex dark‐field contrast and its retrieval in x‐ray phase contrast imaging implemented with Talbot interferometry
Abstract
Under the existing theoretical framework of x‐ray phase contrast imaging methods implemented with Talbot interferometry, the dark‐field contrast refers to the reduction in interference fringe visibility due to small‐angle x‐ray scattering of the subpixel microstructures of an object to be imaged. This study investigates how an object's subpixel microstructures can also affect the phase of the intensity oscillations.
