In the treatment, a tumour is heated up to the therapeutic temperature between 42 and 45 degrees oithout overheating the surrounding normal tissues. There are a few methods for heating cancer cells situated inside the human boky. Especially, the authors have been studying the coaxial-slot antenna, whith is made of a thin coaial cable, for microwave hyperthermia. The coaxial-slot antenna can be employed for interstitial as well as intracavitary microwave hyperthermia. \nThe authors have experienced saveral cases of actual treatments of interstilial microwave hyperthermia for neck tumours by use of th coaxial-slot antennas and have confirmed their effectiveness[1]. In this paper, investigations of the coaxial-slot antenna for interstitial microwave hyperthermia aiming at the treatment of brain tumours, and preliminary studies of the antenna for intracavitary microwave hyperthermia aiming at the treatment of bile duct carcinoma are described. \nAbstract on Annual Scientific Meeting of Institute of Physics and Engineering in Medicine, Annual Scientific Meeting of Institute of Physics and Engineering in Medicine}, title = {Coaxial-slot antennas for interstitial and intracavitary microwave hyperthermia}, year = {2005} }
