Abstract

This paper is a summary discourse on the real time navigator approach to suppressing motion effects in coronary magnetic resonance angiography. The concept of the navigator approach, characteristics of coronary motion, design of navigator echoes for motion measurements, and navigator algorithms for motion effect suppression are reviewed and discussed. At the conclusion, an efficient and effective navigator method is suggested for suppressing motion effects in coronary MRA.

实时导航方法在冠状动脉MRA运动问题中的应用
本文就利用实时导航技术抑制冠状动脉磁共振血管造影中的运动效应进行综述。综述和讨论了导航方法的概念、冠状动脉运动的特点、用于运动测量的导航回波设计以及用于运动效应抑制的导航算法。本文提出了一种有效抑制冠状动脉MRA运动效应的导航方法。
