Abstract

This paper describes a 3D finite element formulation used for radiofrequency hyperthermia problems. Edge finite elements have been coupled with an absorbing boundary condition. Results are presented in term of specific absorption rate. They are compared to experimental measurements performed on a phantom having equivalent electromagnetic properties to human tissues. This comparison shows a good agreement between both numerical and experimental results. Simulations are also achieved on a heterogeneous phantom. The model is then used on a real geometry coming from computerized tomography scans.
