Temperature control and thermal dosimetry by microwave radiometry in hyperthermia

Abstract

Presents a synthesis of works undertaken by the Hyperthermia Group of Lille (France) concerning the utilization of microwave radiometry for temperature control in hyperthermia therapy. This technique of noninvasive temperature control within biological tissues has been integrated on many hyperthermia systems now commercialized. The authors describe the principle of a new radiometer as well as the calculation of the radiometric signals. This allows a noninvasive determination of thermal maps inside tissues during the hyperthermia treatments. Many comparisons between theory and experiment have validated the authors' models of thermal dosimetry and provide a quantitative guidance for the planning of hyperthermia treatments.
