Abstract
A system and method reduce the noise, and hence improve the usefulness, of computer tomography (CT) images that have been corrupted by metal-induced reconstruction artifacts. Metal-induced reconstruction artifacts in CT images are reduced by restoring crucial quantitative image information. The system does not fail when applied to sparsely-sampled and/or low-resolution projection data and is clinically viable in that it is a method that can be embodied in a practical, real-world system that can be used routinely in hospitals and medical clinics, and relies only on data that are available from standard medical CT scanners.
