3D Simulation of Ultrasound Propagation in Human Scull

In this paper, the 3D computer simulation of ultrasound propagation in scull during neurosurgical treatments is described. Neurosurgery treatment of brain tumors often result with damage of healthy tissue so simulation is necessary. The simulation was carried out in three-dimensional space. The method of simulation is virtual source model, with calcuation of important wave phenomena. The measurements were carried out on real scull, in order to check the precision of simulation. The results of simulation are indicating the undesirably high level of ultrasound energy in the central part of temporal lobe. This can cause damage to healthy tissue of speech, motor and sensory functions.
