TEMPERATURE CONTROL AND THERMAL DOSIMETRY BY MICROWAVE RADIOMETRY IN HYPERTHERMIA

This paper presents a synthesis of works undertaken by the Hyperthermi a Group of Lille (France) concerning the utilization of the microwave radiometry for the temperature control in hyperthermia therapy. This t echnique of noninvasive temperature control within the biological tiss ues has been integrated on many hyperthermia systems now commercialize d. We describe the principle of a new radiometer as well as the calcul ation of radiometric signals, They allow a noninvasive determination o f thermal maps inside tissues during the hyperthermia treatments. Many comparisons between theory and experiment have validated models of th ermal dosimetry whose provide a quantitative guidance for the planning of hyperthermia treatments.
