A Splitting-Based Iterative Algorithm for Accelerated Statistical X-Ray CT Reconstruction
Statistical image reconstruction using penalized weighted least-squares (PWLS) criteria can improve image-quality in X-ray CT. However, the huge dynamic range of the statistical weights leads to a highly shift-variant inverse problem making it difficult to precondition and accelerate existing iterat...
