Sequentially reweighted TV minimization for CT metal artifact reduction.

Abstract

PURPOSE Metal artifact reduction has long been an important topic in x-ray CT image reconstruction. In this work, the authors propose an iterative method that sequentially minimizes a reweighted total variation (TV) of the image and produces substantially artifact-reduced reconstructions. METHODS A sequentially reweighted TV minimization algorithm is… (More)
