Abstract

Investigations on shear wave velocities in a large number of elastoplastic muscle tissues of dead animals (ox, sheep, and goat) were carried out at 1 MHz frequency by the ultrasonic pulse transmission technique and their rigidity and stiffness modulus estimated after determining the density due to displacement in mercury. Information on compressional wave velocity and acoustic impedance, together with the elastic properties and some results on shear velocity anisotropy are also presented. It is interesting to note that irrespective of organ, species and direction of measurement, the results of velocity, rigidity and stiffness fall within very narrow limits owing to their nearly identical amino acid composition.

摘要

通过超声脉冲传输技术，在1兆赫兹频率下对大量死亡动物（牛、绵羊和山羊）的弹塑性肌肉组织进行了剪切波速度研究，并在通过汞中位移确定密度后估算了它们的刚性和刚度模量。还给出了纵波速度和声阻抗信息，以及弹性特性和一些剪切速度各向异性的结果。值得注意的是，无论器官、物种和测量方向如何，由于它们的氨基酸组成几乎相同，速度、刚性和刚度的结果都落在非常狭窄的范围内。
