Abstract:
*Purpose*: Reconstruction of X-ray computed tomography data remains a mathematically challenging problem in medical imaging. Complementing the standard analytical reconstruction methods, sparse regularization is growing in importance, as it allows inclusion of prior knowledge. The paper presents a method for sparse regularization based on the curvelet frame for the application to iterative reconstruction in X-ray computed tomography. *Methods*: In this work we present an iterative reconstruct...     »
