| Outline of Final Research Achievements |
Radio frequency ablation treatment has become the most popular thermal therapy in Japan. We aim to improve the accuracy of the radio frequency ablation so that we developed an ablation supporting system based on the accurate bio-heat transfer model and electromagnetism model. We employed the model-based control method to construct the numerical analysis method and electric current control actuator minimal invasively, which can adjust the electric volume based on the bio-heat transfer model to calculate the temperature distribution of tissue. In addition our proposed system was evaluated in both in vitro and in vivo experiments. Both of the experimental results showed our proposed system is possible to ablate tissue reaching the desired temperature, which was viewed suspicion by medical reports. Thus, our proposed method will contribute to improve the ablation supporting system and realize a much more accuracy thermal therapy in future.
