This paper describes the effectiveness of the developed simulator system for performing an effective hyperthermia treatment with needle applicator in a virtual reality (VR). Since a human brain is protected by a skull, it is not easy to non-invasively heat deep brain tumors with electromagnetic energy for hyperthermia treatments. Generally, needle applicators were used in clinical practice to heat brain tumors. However in a clinic, it has some problems. One is that it is not easy to put a needle applicator into a target point for a medical doctor. So, a supporting system for performing an effective hyperthermia treatment is required in the clinic. In this paper, first, we presented the FEM model on 3-D computer graphics (CG). Finally, we calculated temperature distributions using the 3-D FEM model with blood perfusion. From these results, it was found that the proposed VR system is effective for performing hyperthermia treatments.
