Regularization Methods for Phase Retrieval and Phase Contrast Tomography

Abstract EN

Phase contrast tomography is a high sensitivity medical imaging technique.

Several regularization methods have been used in the literature to obtain stable solutions for the phase retrieval or the phase contrast tomography problems.

Yet, the functional framework and the convergence properties of the methods have not been studied in detail.

In this work, the convergence properties of regularization approaches for phase retrieval and phase contrast tomography are investigated.
