| Research Abstract |
To develop a novel ablation treatment system of tongue cancer, the heating properties of a prototype Ti-coated needle with a 26.5mm length were investigated in an AC magnetic field. The effect of the inclination angle was completely eliminated in the newly designed needle, suggesting that the non-oriented heating property relative to the magnetic flux direction allows the precise control of the ablation temperature. In the magnetic field analysis, simulation images of the current density and Joule loss density were obtained for the prototype Ti-coated ablation needle. Moreover, the heat transfer behavior was simulated for the tissue-mimicking phantom subjected to the insertion of the prototype Ti-coated ablation needle in order to visualize their temperature distribution.
