Abstract

Microwave thermal therapy is one of the modalities for cancer treatment. There are several schemes of microwave heating. The authors have been studying thin coaxial antenna for intracavitary microwave heating aiming at the treatment of bile duct carcinoma. Up to now, the heating characteristics of the antenna are investigated by numerical simulation and experiment using a tissue-equivalent phantom. In this study, temperature rises around the antenna inserted into an actual liver tissue of swine are measured. As a result of the measurement, relation between effective heating region and input power to the antenna was found.
