Noise properties of CT images reconstructed by use of constrained total-variation, data-discrepancy minimization

PURPOSE: The authors develop and investigate iterative image reconstruction algorithms based on data-discrepancy minimization with a total-variation (TV) constraint. The various algorithms are derived with different data-discrepancy measures reflecting the maximum likelihood (ML) principle. Simulati...
