A Microwave Apparatus for Producing Uniform Hyperthermic Temperatures Over Large Surfaces

Abstract

A microwave apparatus that can produce uniform hyperthermic temperatures over large surface fields is described. The apparatus consists of a 2450 MHz power generator, a PIN diode power controller, a low-leakage non-contacting microwave applicator with an integral non-contacting infrared thermometer, a thermostat that provides feedback control and can be set to the desired tissue temperature, and a computer controlled mechanical arm that scans the applicator and the infrared thermometer over the treatment field.
