本文报道了一种全自动化超声脉冲回波谱分析测量系统。该系统具有对超声回波信号进行快速选择性采样、存贮、数字分析与处理及微机程序软件控制三维机械扫描等功能,可对生物组织样品的超声衰减系数谱、背向散射系数谱及回波谱自相关进行测量与分析。对一系列哺乳动物软组织样品所做的实验研究表明,该测量系统给出了令人满意的研究结果。
This paper reports a fully automated ultrasonic pulse echo spectroscopy measurement system. The system has the functions of rapid selective sampling, storage, digital analysis and processing of ultrasonic echo signals and software control of three-dimensional mechanical scanning by computer program, etc. It can measure the ultrasonic attenuation coefficient spectrum, backscatter coefficient spectrum and back Spectral autocorrelation measurement and analysis. Experimental studies on a series of mammalian soft tissue samples show that the measurement system gives satisfactory results.
