Application of ultrasonic microscopy in biomechanical properties measurement of cancellous bone

目的:超声显微扫描是利用超声波的反射原理获得标本的声阻抗信息。介绍超声显微技术在松质骨生物力学测试中的应用。方法:本文以大鼠股骨头有机玻璃包埋标本作为测试件,通过超声显微镜扫描采集骨标本的灰度图并对其分析。结果:对灰度图的计算分析可以得出骨标本的声阻抗值。结论:该方法的应用可以更好地解释骨组织显微结构上的生物力学特性。

Objective：Ultrasound scanning can provide the information of acoustic impedance through the ultrasonic reflection theory. This study tries In introduce the application of the uhrasonie technique in predicting biomechanical properties of cancellous bone. Methods：The rat femoral head embedded in plexiglass was used as the bone specimens for ultrasound scanning and the gray scale images scanned by ultrasound microscope were collected and analyzed. Resnits：The value of acoustic impedance was calculated by analyzing the gray scale image. Conclusion ：The application of uhrasonic microscopy can show more value about the microstrueture of biomechanical properties of bone tissue.
