Abstract
A hyperthermia treatment device comprises paired multiple feed inductor rings positioned between two capacitor plates, for producing a tuned radiofrequency electromagnetic field. The spatial orientation of the elements and/or the phase of the current flowing through them is variable. Change in the spatial orientation and phase of the inductor rings produce asymmetric magnetic field patterns resulting in the development of asymmetric eddy current patterns orthogonal to the magnetic lines of force. The eddy current patterns are further focused by spatial orientation and phase adjustment of the capacitor plates. A movable grounding point is utilized to further focus induced eddy currents. The device is capable of producing focal hyperthermia at depth to heat specific volumes.
