X-ray Tensor Tomography Reconstruction

Quite recently, a method has been presented to reconstruct X-ray scattering tensors from projections obtained in a grating interferometry setup. The original publications present a rather specialised approach, for instance by suggesting a single SART-based solver. In this work, we propose several improvements, among them a more abstract approach to solving the inverse problem, thus allowing the use of other algorithms than SART (like conjugate gradient), a faster tensor recovery, and an intuitive visualisation.     «
