The Application of a Re-entrant Type Resonant Cavity Applicator to Deep and Concentrated Hyperthermia

Abstract

We present a newly type applicator using a re-entrant resonant cavity for deep and concentrated hyperthermia. In this system, a human body is placed between the gap of the re-entrant resonant cavity, and is heated by standing wave electromagnetic fields.From the results of computer simulations using a three layers disk phantom, that is, fat-muscle-fat model, it is shown that the deep and local tumor may be heated effectively without generating any hotspot or edge effects as in the case of RF capacitive heating method.
