摘要

冠状动脉成像需要高时间分辨率和高空间分辨率，以避免运动伪影。为了获得更好的时间分辨率，人们采用了几种方法，包括更快的旋转速度和双管系统。在本文中，我们提出了一种使用运动估计和补偿的替代方法。结果表明，该方法能显著降低冠状动脉成像中的运动伪影。

Coronary artery motion estimation and compensation: A feasibility study

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.
