High-intensity focused ultrasound (HIFU) is a noninvasive method for cancer treatments. However, there is a problem that it takes for several hours to treat a large tumor. To shorten the treatment time, there is need for the development of a highly-efficient method. It is known that cavitation bubbles accelerate the HIFU heating treatment. In this study, the enhancement of the heating by cavitation was estimated in a numeral simulation solving a bio-heat transfer equation by increasing the absorption coefficients and heat source in and out of the volume of cavitation bubbles. The absorption coefficient and the amount of the generated heat were calculated by a curve fitting between the temperature rise in experiment and simulation. Finally, we investigated the accuracy of the model by measuring acoustic emission from cavitation in a focused ultrasound field. |
