Hyperthermia treatment planning requires information technology and management to provide best quality of medical tumor treatment. Radiofrequency ablation (RFA) has been recognized as one of promising minimally invasive liver tumor treatment around the world. The purpose of this study is to present 3-D visual computer simulation for tumor treatment planning and to evaluate the impact of NaCl injected saline solution (which electrical conductivity is higher and could enlarge thermal lesion volume through RFA) on treated tumor tissue by internally-cooled radiofrequency ablation electrode in liver tumor. The temperature required to ablate tumor cells is approximate conservatively at least 55 ℃ and thus was set as a threshold to measure lesion size. As to computer models, the mathematical equations use Laplace equation of electric field calculation, and Bio-heat transfer equation of calculation temperature field. Numerical methods will consider Gauss-Seidel iteration to obtain 3-D transient finite difference solutions of a set of partial differential equations. Static internally-cooled water temperature condition is implemented in numerical iterations.
