There exists a growing body of research that relates the measurement of pressure-wave velocity in bone to different physiological conditions and treatment modalities. The shear-wave velocity has been less studied, although it is necessary for a more complete understanding of the mechanical properties of bone. Ultrasound critical-angle reflectometry (UCR) is a noninvasive and nondestructive technique previously used to measure pressure-wave velocities both in vitro and in vivo. This note describes its application to the measurement of shear-wave velocity in bone, whether directly accessible or covered by soft tissue.
越来越多的研究将骨中压力波速度的测量与不同的生理状况和治疗方式联系起来。尽管剪切波速度对于更全面地理解骨的力学特性是必要的，但对其研究较少。超声临界角反射测量法（UCR）是一种非侵入性和非破坏性技术，以前用于在体外和体内测量压力波速度。本报告描述了它在测量骨中剪切波速度方面的应用，无论骨是直接可及的还是被软组织覆盖的。
