This paper describes the possibility of a new heating method, with a needle applicator made of a shape memory' alloy (SMA), to expand the heating area for interstitial brain tumor hyperthermia treatments. The purpose of the study described here is to show the capability of the method to expand a defined heating region with a developed three-dimensional human head model using the finite element method (FEM). One major problem is that commercial software cannot calculate cooling energy coursed by blood flow. So, this study incorporates instructions into a software program to account for this. From these results, it was confirmed that the proposed method can expand the heating area and control the heating of various sizes of brain tumor
