Various types of medical applications of antennas have widely been investigated. Since these antennas are used in and around a human body, the size of the antennas must be small. Particularly, in order to realize minimally invasive treatment, small-size antennas are desired. This paper describes a few antennas for hyperthermia which is one of thermal therapies for cancer. The authors et al. have developed...
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...
Hyperthermia is one of the modalities for cancer treatment, utilizing the difference of thermal sensitivity between tumor and normal tissue. The authors have developed a coaxial-slot antenna for microwave hyperthermia. In this paper, calculated results of temperature distributions around the coaxial-slot antenna for the treatment of brain tumor and bile duct carcinoma are described
The authors have been studying thin coaxial-slot antennas for interstitial microwave thermal therapy. In this paper, firstly, the structure of the coaxial-slot antenna is briefly reviewed. Secondly, the procedure for temperature calculation around the antennas and the calculation model based on the CT images of the patient are described. Thirdly, the blood flow rate of the tissue concerned during...
