Coronary artery motion estimation and compensation: A feasibility study
Nuclear Science Symposium Conference Record（2010）
摘要
High temporal resolution and high spatial resolution are required to image the coronary arteries without motion artifacts. Several approaches have been pursued to achieve better temporal resolution including faster rotational speeds, and dual tube systems. In this paper, we present an alternative approach using motion estimation and compensation. The results demonstrate that the proposed methods can significantly reduce motion artifacts in coronary artery imaging.
