Hyperthermia treatment requires two procedures. One procedure is to heat tissues up to a suitable therapeutic condition. The other way is to monitor the tissue temperature under treatment. Monitoing the temperature, especially in a noninvasive manner, is more difficult than the heating procedure. In this paper, some methods of noninvasive temperature measurements are introduced and their underlying difficulties are discussed.
It is concluded that the most promising method is the temperature measurment method which uses temperature coefficient of sound propagation speed. In addition the maximum accuracy of this method was found to be around 0.2°C
