摘　　要：利用冠状动脉造影图像序列进行二维和三维血管运动的分析与估计,对于准确估计与解释心脏的运动,从而正确诊断心血管和心脏疾病都十分关键。为了使人们对该领域的研究现状有一个较为全面的了解,本文对它的研究和进展做了较系统的论述,列举了现有的运动估计算法,并分析了这些方法的优缺点。最后分析了其未来发展方向。Analysis and estimation of coronary artery motion using X--ray angiography are essential in order to as- sess and interpret cardiac motion accurately and diagnose some cardiac pathologies related to coronary circulation deficiencies,or to myocardial anomalies. The paper makes an introductory review on the artery motion estimation from angiogram sequence including the last achievement in this field. Some methods are listed including their the- ory,advantage and drawback. Finally, it makes a discussion on some open problems and point out possible direc- tions for further research.
