In the interstitial or intracavitary hyperthermia, two electrodes are usually used to heat the deep-seated tumor ; one is the internal electrode and the other is the external flat electrode for RF current field heating. In some case, three electrodes are used ; one is the internal electrode and the remainders are two external flat electrodes. In order to compare the two methods, SAR simulations have been performed on the interstitial or intracavitary hyperthermia using one internal electrode with one external flat electrode and one internal electrode with two external flat electrodes for RF current field heating. The results suggest that the heating region could be controlled by the position of the external electrodes and the heat diffusion could be reduced for the three electrodes method because of whole heating effect.
