Abstract

In this paper, the 3D finite-element simulation of ultrasound brain surgery is demonstrated. The pressure variations are obtained using Helmholtz equation and temperature distributions resulting from acoustic absorption are calculated by employing bioheat equation. Our results show that with increase of the pressure, focal temperature is increased. With using appropriate pressure amplitude, surgical time duration could be decreased and this could lead to minimal side effect of ultrasound heating of the surrounded healthy tissue.
