Hyperthermia is a well-known treatment for cancer. When the tumor volume is somewhat large, a temperature difference occurs between the tumor core and the near edge. High-temperature hyperthermia is proposed to keep the temperature of the heaters high. The soft-heating method used excites a thermosensitive magnetic heater in a high-frequency magnetic field. The temperature distribution when two or more heaters were used was measured for a hybrid heater composed of thermosensitive magnetic material and a metal ring, and the effective area for hyperthermia was examined.
