Abstract

Hyperthermia is one of the therapeutic techniques that attempt to mainly induce necrosis in cancer cells by heating. To cause necrosis in tumors under hyperthermia with certainty, the authors proposed high-temperature hyperthermia. For this study, the authors examined the heat characteristics of the heat element composed of a thermosensitive magnetic material and a metal ring with various volumes. Our results showed that heat characteristics have a tendency to saturate with an increase in element volume.
