ABSTRACT:
An RF hyperthermia applicator for inducing a temperature rise in a human female breast for treating carcinomas includes a waveguide applicator having an aperture and a phased-array of monopole electric field radiators coupled to a source of electric field energy for producing electric field radiation output from the waveguide through the aperture. Compression means is used for compressing a human breast to a predetermined thickness. The waveguide is positioned adjacent to the compression means such that the breast is positioned adjacent to the aperture and thereby receives electric field radiation from the waveguide. In another embodiment, at least two waveguide applicators are positioned on opposite sides of the compression means so that the compressed breast is positioned between the opposed apertures of the waveguides. An electric field probe is placed into a target within the breast to assist in focusing the electric field energy into the target.
