摘　　要：肌肉是构成人体的重要组织,通过肌肉的收缩可以引导和控制身体的运动。目前可以通过肌电图学(Electromyography)、核磁共振成像(Magnetic Resonance Imaging)和超声成像的方法来评估肌肉功能。定量超声(Quantitative Ultrasound)可以提供有关肌肉结构的定量数据及其在收缩过程中的实时变化,正逐步成为一种可靠的研究和临床工具,在肌肉功能的评估中正扮演着越来越重要的角色。本文总结了定量超声在肌肉评估中的三个方面:肌肉功能性评估、人体运动分析和肌肉硬度(弹性)检测,并且讨论了当前定量超声在肌肉评估中的主要问题和困难。Skeletal muscle is an important tissue of human body,and its contraction can control and regulate body motions.Currently,muscle assessments are commonly performed using electromyography（EMG）,magnetic resonance imaging（MRI）,and ultrasound imaging.Quantitative ultrasound can provide objective data about muscle architectures and their change during muscle contraction in real-time.It is gradually becoming a reliable research and clinical tool and playing increasingly important role in the functional assessment of muscles.This paper gives a review on the three aspects of quantitative ultrasound for muscle assessment,including muscle functional evaluation,human motion analysis,and muscle elasticity measurement.The problems and challenges in this area are also discussed.
