Abstract :
A heating method using a re-entrant-type resonant cavity applicator for deep-seated hyperthermia treatment and its computer simulation are described. In this heating method, a human body is placed in the inner gap of the cavity and is heated by standing-wave electromagnetic fields. From the results of computer simulations using a disk phantom, it is shown that a deep and local tumor may be heated effectively without generating any hot spots or edge effects as in the case of an RF capacitive heating method
