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 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. Its dimensions allow a relatively large circumferential air gap when placed around the torso so that it is convenient to use and is non-threatening to the patient.
