ABSTRACT:
A microwave dipole probe for in vivo localized hyperthermia includes an outer conductor and an inner conductor extending through and beyond the outer conductor. The portion of the inner conductor extending beyond the outer conductor is expanded in diameter relative to the portion within the outer conductor. A dielectrically loaded phase reversal sleeve is folded over the outside of the outer conductor and contains a dielectric loading material similar to the dielectric constant of the in vivo target volume.
