Abstract

One severe problem with heating in hypothermia and hyperthermia treatment is the accurate measurement and control of temperature in the presence of a strong electromagnetic field. For this purpose, a fiber-optic radiometer system based on a nonmetallic, infrared fiber probe, which can operate either in contact or noncontact mode, has been developed. In preliminary investigations, the radiometer worked well in a strong microwave or radiofrequency field, with an accuracy of +or-0.5 degrees C. This fiber-optic thermometer was used to control the surface temperature of objects within +or-2 degrees C.
