A row-action alterative to the space-alternating generalized expectation-maximization algorithm for image reconstruction in positron emission tomography

The space-alternating generalized expectation (SAGE) maximization algorithm has been successfully used in image reconstruction due to its rapid convergence. In this paper, a row-action alternative to the SAGE algorithm (RASAGE) is proposed; it processes the projection data sequentially. In order to...
