Submillimeter Wave Irradiation of Living Bodies using a Gyrotron and a Catheter

Abstract

The development of a submillimeter wave catheter for irradiating on living bodies using a gyrotron as the radiation power source is described. The gyrotron FU-IV is optimized for development. The gyrotron is operated in the CW mode at a frequency of 302 GHz under a magnetic field of approximately 11 T. Irradiation tests using various antennas were performed on cow livers, living rats and malignant tumors implanted in living mice. Irradiation results were considered based on the microwave theory and ray optics.
