MONOPOLE PHASED ARRAY THERMOTHERAPY APPLICATOR FOR DEEP TUMORS |
摘要 |
A monopole phased array thermotherapy applicator radiating radiofrequency energy for inducing a temperature rise in a target within a body includes a plurality of monopole elements for transmitting electric-field radiation; a metallic waveguide with an RF reflecting ground plane surface with a plurality of circular holes for mounting the monopole elements where the metallic waveguide forms an aperture for receiving a body to be treated; a waveform generator providing a source of electric field coupled to each monopole radiation element through a respective phase and power weighting network; at least one electric field probe positioned on a skin surface of the body for detecting electric field radiation from the plurality of monopole elements; and a controller circuit coupled to the electric field probe received feedback signals to adjust the phase and power delivered to the plurality of monopole elements so that one or more adaptive nulls are formed on the surface of the body and a focus is formed at the target tissue to be treated with thermotherapy. |
