감온페라이트를 이용한 발열체의 발열특성에 관한 기초연구

Abstract

Hyperthermia known as the new treatment way of cancer tumor, treats cancer by destructing cancer tumors by keeping the body or organ temperature as 41.8℃, and this enables automatic physiological temperature control, within the temperature where Hyperthermia effect is overcome. Previous ways of partial treatment such as ultrasonic waver, micro wave, R.F. Induction heating affected the whole body, which makes some parts more than 45℃, and it destruct normal cells as well, therefore it is very important to keep the temperature in cancer treatment. Usually ferrite material has Curie Temperature, which lose its magnetic force when it comes to this temperature. Using this it's easy to keep the target temperature regularly. In this study, Curie Temperature of ferrite has been used to get and keep Curie exothermic Temperature. Using temperature sensitive ferrite and metal ring as thermal seeds, studied exothermic characteristics of thermal seed at normal temperature by induction heating.
