| Research Abstract |
Modeling and simulation for the enhancement of heating due to inertial cavitation in high-intensity focused ultrasound (HIFU) were studied. Results in in vitro experiments were qualitatively reproduced by the developed numerical method. Impacts of the properties of microbubble for ultrasound frequency and amplitude, the properties of surrounding tissue, initial void fractions and spatial distribution of microbubbles on both heating region and heating efficiency were numerically clarified.
