Abstract

While fiberoptic thermometry offers a number of inherent advantages for measurement and control during use of rf or microwave-induced hyperthermia as an adjunct to radiation therapy, early fiberoptic thermometry systems exhibited a variety of limitations which have impeded full acceptance and utilization of the technology. Recently, a new technique based on the measurement of the fluorescent decay time of a magnesium fluorogermanate phosphor sensor has been introduced. This paper describes an eight-channel system utilizing the new technology which has been developed specifically for use in hyperthermia and other rf-field applications. The system utilizes a probe made from four small plastic fibers. This probe is available in the form of either a four-sensor linear array or four single-sensor fibers. Performance data taken independently under simulated clinical use indicate that this system substantially overcomes the limitations of previous fiberoptic systems.
