Estimation of Tissue Temperature in Tumor Hyperthermia Using Ultrasonic Methods

Estimation of tissue temperature in Tumor Hyperthermia is an extremely important assurance of therapeutic safety. In all kinds of measuring methods, ultrasonic nondestructive techniques are the safest and the most promising one. The main ultrasonic methods of temperature measurement are based on ultrasonic echo signal, acoustic transmission signal, the characteristic parameters of ultrasonic image, theoretical model simulation and so on. The theories of various ultrasonic methods adopted for measuring tissue temperature are introduced in this paper with their application, limitation and research status analyzed respectively.
