Study on Noninvasive Temperature Measurement in Biological Media Using Ultrasonic Nonlinear Parameter B/A

摘要

Application of the temperature dependence of ultrasound nonlinear parameter B/A can realize noninvasive temperature measurement in biological media. The principle of temperature measurement is described and an experiment system is set up. The experiments for measuring the nonlinear parameter B/A and estimating their temperature dependences in tested media are described. Preliminary experiment results are presented.
