Abstract
Today the medical applications of the microwaves are gaining popularity in various area of clinical treatment. The authors et al. have been studying on the characteristics of the coaxial-slot antenna for interstitial microwave hyperthermia. Although it is an invasive technique, the interstitial hyperthermia is considered to be effective to large volume and deep-seated tumors. In this report, some calculated results of the SAR (Specific Absorption Rate) patterns in the multi-layered media are displayed. Next, the temperature patterns inside the human body are calculated for effective treatment planning.
