Abstract
High Intensity Focused Ultrasound (HIFU) therapy has been developed for the treatment of deeply-placed cancer such as the liver and brain cancer. Problems are the displacement of focal point due to the reflection and refraction of ultrasound at the interfaces of bones and the attenuation of ultrasound due to the skins, fat and tissues. To minimize the invasive region of tissues by HIFU, the numerical simulation is available for the. prediction of the treatment of tissues. The development of the numerical simulation of ultrasound propagation through the voxel modeled body based on the MRI and CT data is reported. The results of the three-dimensional computation show the displacement of focal point for the ultrasound of 1MHz through the bone plate in water.
