NON-INVASIVE APPARATUS AND METHOD FOR PROVIDING RF ENERGY-INDUCED LOCALIZED HYPERTHERMIA

摘要

An apparatus for providing hyperthermia treatment for enhancing cancer therapy includes an applicator body and a plurality of antennas operatively associated with the applicator body. The applicator body has a concave profile extending from an aperture and defines an open cavity for receiving RF standing waves. The antennas are arrayed for transmitting RF standing waves at respective selected amplitudes and relative phases into the cavity and generally toward a tumor-containing tissue disposed in operative alignment with the antennas. In use, the tissue such as breast or chest wall is immersed in the cavity or supported on a pillow mounted to the cavity. The cavity contains a fluid such as deionized water through which the RF energy is transmitted to heat the tissue. The hyperthermia treatment can be used to enhance the effects of a cancer-related therapy such as radiotherapy or chemotherapy.
