Abstract :
Hyperthermia is one of the modalities for cancer treatment, utilizing the difference of thermal sensitivity between tumor and normal tissue. Up to now, the authors have been studying various coaxial-slot antennas for microwave hyperthermia. A coaxial-slot antenna aiming at intracavitary heating for bile duct carcinoma has been especially developed. In this paper, heating performances of such an antenna are estimated for the actual treatments. As a result of the investigations, the possibility of this treatment by use of the proposed coaxial-slot antenna could be confirmed
