摘要

提出了一种基于数字信号处理器（DSP）的软组织弹性的检测方法

以DSP为核心

通过测量超声信号和力信号

计算出软组织的厚度

然后

利用直接互相关算法计算出软组织在不同力下的形变

利用施加力的数据和其对应的形变数据

拟合出软组织的弹性参数

以新鲜的猪皮、猪脂肪、猪肉为标本进行了实验

并给出了实验结果。

Abstract

A method based on digital signal processor（DSP） for detecting the elasticity of soft tissue is given.Used DSP as main unit

the thickness of soft tissue is calculated through force signals and ultrasonic signals

the deformation is also calculated under different force used correlation algorithm.The elasticity parameters are got by curve-fitting through force data and deformation data.At last

experiment was did used pig’s skin

pig’s fat and pig’s muscle as specimen and the results were given.
