A Regularized X-ray Tensor Tomography Reconstruction Technique
International Conference on Image Formation in X-Ray Computed Tomography, Bamberg, Germany, July 2016 (bib)
|X-ray Tensor Tomography (XTT) is a novel imaging modality for reconstruction of three-dimensional X-ray scattering tensors from dark-field projections obtained in a grating interferometry setup. In this work we propose a new component-based total variation (TV) regularized conjugate gradient (CG) reconstruction method for XTT data. First results suggest that the proposed methodâ€™s convergence rate is comparable to different regularization methods, while the resulting reconstructions show less noise and streak artifacts compared to previous, unregularized method.
