ABSTRACT:
The present invention discloses an improved electrode for use with apparatus employing radio frequency energy for deep heating of materials. In particular, it is adapted for the medical treatment of living animal tissue by hyperthermia. The electrode comprises a single loop turn having capacitance associated therewith so as to resonate the electrode for maximum power transfer thereto. The electrode causes a field to be generated within the annular region enclosed by the electrode comprising a plurality of concentric, substantially equally powered lines of force in which the living tissue to be treated is disposed. The electrode finds particular use in the treatment of deep seated cancers in patients.
