Apparatus for localized heating of a living tissue, using electromagnetic waves of ultra high frequency, for medical applications
First Claim
1. An apparatus for localized heating of living tissues, using electromagnetic waves of ultra-high frequency comprising an ultra-high frequency generator, a transmission line having one end connected to said ultra-high frequency generator, a switch with two inputs and one output, one input being connected to another end of said transmission line, a probe connected to the output of said switch, said probe capable of emitting said ultrahigh frequency waves and designed for being introduced into living tissues to be heated, and radiometric means for monitoring the temperature of said living tissues in contact with said probe, said radiometric means comprising a radiometry receiver connected to the other input of said switch, said receiver capable of measuring the electromagnetic radiation re-emitted by said living tissues and picked up by said probe.

Abstract
An apparatus for thermal treatment of the human body, using electromagnetic waves (200 to 2500 Mc/s) and radiometric receivers for monitoring and possibly controlling the temperature reached by the living tissues. A generator at ultra high frequency delivers a power of about one Watt into a coaxial cable terminated by a probe emitting electromagnetic waves in the organ to be heated by dielectric losses in the medium. A multichannel receiver, switched at intervals, analyzes the radiation reemitted by the living tissues through the probe, then utilized as a receiving antenna. The temperature reached in a region surrounding the probe is deduced therefrom and can be utilized for controlling the power emitted through a servocontrol system.
