High-resolution human anatomy models for advanced electromagnetic field computations

Abstract

High-resolution anatomy models are used in the computation of induced electromagnetic fields, SAR, and temperature profiles in the human body. In particular, the HUGO model with a voxel resolution of up to 1/spl times/1/spl times/1 mm allows accurate modeling of more than 30 distinct human organs and tissues. The numerical calculations use the finite integration technique, which proves appropriate for the voxel-based human models. Simulation results for the induced electromagnetic fields in the human head due to the high-frequency radiation of a cellular phone are given. In a second application the electromagnetic field pattern and temperature distribution in the human body in regional hyperthermia therapy are calculated.
