Abstract
Acoustic-inversion method for a noninvasive temperature measurement in tissue is presented. A set of B-scan operating in M-mode was used as a signal-equipment. The echoes reflected from an assigned surface in tissue were acquired before and after heating, and the corresponding spectra were then obtained by FFT. In order to conduct the acoustic-inversion method, a theoretical formula given by authors in another paper was invoked. The optimization algorithm was implemented to fit the spectra to the measured data and calculate changes in temperature.
