Abstract

Thermal effect of high-intensity focused ultrasound on biological tissue behind the rib cage phantom has been numerically simulated. A phased array was used as a source of ultrasound. Temperature and thermal dose distributions in the biological tissue were calculated and used to find the form of thermal lesions. The results of the calculations are in good agreement with experiment and show that the model is applicable for predicting the effect produced by ultrasound in tissue.
