ABSTRACT:
An electrostatic deep heating applicator deposits RF energy in a relatively uniform manor throughout a given cross-section of the human torso, thus resulting in a similar uniform heating of the region. The applicator uses a pair of identical, rectangular, flat or cylindrical applicators which generate a heat-producing electric field predominantly parallel to the major axis of the body so as to minimize excessive surface heating. The applicator finds particular use in the treatment of deep seated cancers in patients. It need only be placed near the torso for satisfactory operation, thus allowing a relatively large air gap between it and the patient. It requires very minimum set-up time, is convenient to use and is non-threatening to the patient.
