The deposition of ultrasonic energy in tissue can cause tissue damage due to local heating.
For pressures above a critical threshold, cavitation will occur, inducing a much larger
thermal energy deposition in a local region. The present work develops a nonlinear bubble
dynamics model to numerically investigate bubble oscillations and bubble-enhanced
heating during focused ultrasound (HIFU) insonation. The model is applied to calculate two
threshold-dependent phenomena occurring for nonlinearly oscillating bubbles: Shape …
