ANALYSIS OF A HYPERTHERMIC TREATMENT USING A REENTRANT RESONANT-CAVITY APPLICATOR FOR A HETEROGENEOUS MODEL WITH BLOOD-FLOW

Hyperthermic treatment using a reentrant resonant cavity applicator is investigated, By solving time-dependent electromagnetic field - heat transfer equations for a heterogeneous model, temperature distribution s in various organs are obtained. Calculated results show that it is i ndispensable to consider the blood now to predict accurate temperature distributions during a hyperthermic treatment. Also, it is found that the necessity of measuring the electrical and thermal properties of t he abdominal fat accurately as well as optimizing the heating system t o avoid the concentration of electromagnetic energy around the abdomin al fat-muscle interface.
