连续测量组织血液灌注率的计算机系统

A Computer System for the Continuous Measurement of Tissue Blood Perfusion Rate

设计并研制了一个连续、在线测量活组织中局部血液灌注率的计算机测试系统，该系统由干扰热源（圆盘形探头）、测量电路及ＰＣ系列微机２大部分组成。使用本系统可以实现对局部组织血液灌注率的连续、无损伤检测，同时在系统的软件中也为进一步研究、探索某些问题提供了途径，在医学临床诊断中可起到很好的参考作用。

A new method for measuring local tissue perfusion rate is introduced.This method is base on the principle of heat disturbance.The principle of disturbance can be non-damage measurement.A microcomputer system for this measuring is presented in this paper.The whole measuring system introduced consists of three parts:the probe for both disturbing and detecting the information,the circuits for both controlling and measuring,and the microcomputer 386.Three choices of measuring manner are provided as well.
