| Research Abstract |
Treatment for deep local cancer has not yet been established. We propose a hyperthermia treatment method for deep local cancer by using implantable electrodes. In this study, three themes are investigated; 1) A method for suppressing the edge effect of implantable electrode, 2) Energy transmission method from outside body to deep inside body, and 3) Thermal data transmission method from deep inside body to outside body.
As for method for suppressing the edge effect in the implantable electrode, the best electrode model was applied to a numerical human model that included 51 types of tissue and the pancreas (target organ), and the temperature was evaluated. As a result, temperature rise value of 1.5 degrees Celsius in the deep of the target organ and that of 4.5 degrees Celsius near the heating electrodes were obtained when the input power to the electrodes was 2 W at a frequency of 8 MHz.It was found that our system including 1),2) and 3) has a high capacity for deep local heating.
