Abstract

A coupled thermal and electromagnetic modeling of hyperthermia in biological tissues is presented. The thermal processes within the tissues are predicted by using a steady-state bio-heat transfer equation. The rate of volumetric heat generation within the tissues during the passage of microwave irradiation is obtained after solving Maxwell's field equations. All the governing equations have been solved by the finite element method, using C -continuity, three- noded isoparametric elements. The numerical solutions have been validated by comparing with the analytical solutions for a simplified case. Finally, we present the temperature distributions for a real case. The effect of perfusion has been highlighted. Tumor with little blood flow rate shows good therapeutic advantage during hyperthermical irradiation
