Iterative image reconstruction algorithms for ct metal artifact reduction: A review

Research output: Contribution to journalArticle

Abstract

The presence of metals in patients causes streaking artifacts in x-ray CT and has been recognized as a problem that limits various applications of CT imaging. In this article, we will summarize recent developments and patents in software-based approaches for metal artifacts reduction in CT. In particular, we will focus on the iterative image reconstruction algorithms for metal artifacts reduction as well as for accurate determination of the shape and the location of metal objects
