Temperature distributions of developed needle type applicator

This paper discusses radio frequency (RF) interstitial hyperthermia for a brain tumor with needle type applicators. In this method, it is necessary to make appropriate thermal distribution to the region of the brain tumor. However, it is difficult to predict the thermal distribution. We estimated temperature distribution inside an agar phantom by the finite element method (FEM), and heated agar phantom by the developed system. First, we compared computer simulation results and experimental results. Next, we discussed the heating properties of changing the inserted direction of a single type needle applicator. Finally, the temperature distribution of agar phantom heated by a multi type needle applicator was presented
