| Research Abstract |
In this research project, we have developed a catheter apparatus with an insert dielectric rod and sheet antennas suitable for irradiation of a living body. This is the first application of millimeter-and submillimeter-wave irradiation using an insert dielectric antenna for a biological sample. Tests of time and insertion depth dependent irradiation of a cow liver confirm the normal operation of the irradiation apparatus for living bodies because only the irradiated local part is damaged by the power of microwave well controlled
Measurement results of the denaturation region and the surface temperature of irradiated samples in the irradiation study suggest that the dielectric rod and sheet antennas are appropriate for use as a common catheter irradiation apparatus for living bodies such as liver cancer and brain cancer tissues.
Further developments are underway to improve the slim catheter waveguide and to develop an effective antenna to enable localized irradiation.
