Study on Sound Velocity and Temperature Characteristics of Medical Tissue Mimicking Ultrasound Phantoms Materials

超声仿组织模体内部材料声速是检验模体是否正常的重要参数之一,论文通过搭建一种基于交叉结构的声速测量平台,在不同温度条件下,研究模体内部材料声速,获得声速与温度的特性曲线规律,对计量部门校准该模体具有较好的参考作用。

The sound velocity of the material inside the tissue - like phantom is one of the important parameters to check whether the phantom is normal or not. In this paper,a sound velocity measurement platform based on cross - structure is built. Under different temperature conditions,the sound velocity of the material inside the phantom is studied,and the law of the characteristic curve of the sound velocity and temperature is obtained,which can be used to calibrate the phantom for the metrology department. It is a good reference for Metrology Department to calibrate the phantom.
