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

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.
