Abstract

Ring artifacts are one of the most common artifacts in all types of computed tomography (CT) images and are usually caused by inconsistent response of detector pixels to X-rays. Effective removal of ring artifacts can greatly improve the quality of CT images and improve the accuracy of later diagnosis and analysis, which is a necessary step in CT image reconstruction. Therefore, the ring artifact removal method (also known as "ring artifact correction") was systematically reviewed. Firstly, the formation mechanism and performance of ring artifacts were introduced. Secondly, the ring artifact correction methods of hardware correction, software correction and deep learning correction are introduced in turn, and the principle, development process, advantages and disadvantages of each type of method are analyzed. Finally, the advantages and disadvantages of the existing ring artifact removal methods are summarized, and the solutions are prospected.
