Abstract :
Hyperthermia is a therapeutic technique against cancer that attempts to necrotize cancer cells by heating. With this therapy, we proposed a "soft heating" method that uses thermosensitive magnetic materials as heaters. We examined the structure of a hybrid heater for a high-powered soft heating method using a magnetic micromachine drive.
