| Research Abstract |
To develop a novel ablation therapy of renal cancer utilizing a high-frequency induction technique, the heating property of the carbon steel rod embedded into the Ti-tube was investigated in a high-frequency output at 300kHz as well as the fabrication of ablation therapy apparatus. In this preliminary experiment, the effect of the inclination angle to the magnetic flux direction was significantly reduced by choosing an optimum Ti-tube thickness. Based on such results, a prototype ablation needle, which is wholly covered with a Ti layer was fabricated for the clinical use. It should be emphasized that this prototype needle possesses a complete non-oriented heating property to the magnetic flux direction.
