A number of new methods are available for the measurement of large artery elastic properties in human subjects in vivo. One powerful tool which has recently been applied to the study of large artery mechanics is intravascular ultrasound (IVUS). IVUS studies are performed using a high frequency ultrasound transducer mounted on the tip of a catheter. This catheter is inserted into a blood vessel and detailed cross-sectional images of the vessel, are obtained from within the lumen. IVUS techniques have been used to study wall mechanics of the human aorta, as well as peripheral and coronary arteries in normal human subjects and in patients with vascular disease. This paper reviews IVUS studies of human arterial elasticity and discusses the strengths and weaknesses of this emerging technique as it is applied to the understanding of arterial mechanical properties.
目前有许多新方法可用于在体测量人体大动脉的弹性特性。血管内超声（IVUS）是一种最近被应用于大动脉力学研究的强大工具。IVUS研究是使用安装在导管尖端的高频超声换能器进行的。将该导管插入血管内，从管腔内获取血管的详细横截面图像。IVUS技术已被用于研究正常人和血管疾病患者的人体主动脉以及外周和冠状动脉的壁力学。本文综述了关于人体动脉弹性的IVUS研究，并讨论了这种新兴技术在用于理解动脉力学特性方面的优缺点。
