Abstract
A system for internal heat treatment of specific bodies by microwave including a generator 1 of microwave energy at a frequency f0, at least one channel for transmission of the microwave energy, each channel making it possible to generate a modulated microwave treatment signal, the wave of the microwave energy of two consecutive channels exhibiting a phase shift of defined value. At least one microwave applicator is associated with one of the channels in order to ensure application of the microwave energy delivered by this channel at separate adjacent points of the area Z to be treated, and a dual-temperature-reference radiometer is interconnected selectively to the applicator which then plays the role of temperature sensor, the absolute temperature of the adjacent point of the area Z to be treated being thus determined. The microwave powers radiated and the instantaneous temperatures of the separate points of the area Z to be treated are displayed. Application to treatments by hyperthermia, especially of living tissues.
