Antenna Technology for Medical Applications
نویسنده
چکیده
Various types of medical applications of antennas have widely been investigated. In particular, hyperthermia is one of thermal therapies and is a modality for cancer treatment utilizing the difference of thermal sensitivity between tumor and normal tissue. The author et. al. have developed a coaxial-slot antenna, which is one of thin microwave antennas to be employed for interstitial as well as intracavitary microwave hyperthermia. In this paper, two different types of coaxial-slot antennas are introduced for the treatment of brain tumor and bile duct carcinoma. Then calculated results of thermal patterns around the antennas are described.
