Abstract

This paper presents development of a microwave system for noninvasive blood perfusion measurement. The proposed system is based on a thermal perfusion measuring method using microwave techniques. In this method, the tissue temperature is raised by microwave heating (900 MHz) to no more than one degree Celsius, and after the discontinuation of the microwave heating signal, the temperature decay measured using microwave radiometric sensing (1-2 GHz) is indicative of the blood perfusion rate. The preliminary results of the system´s test are provided.
