Title:
EDDY CURRENT INDUCED HYPERTHERMIA USING CONDUCTIVE PARTICLES
Document Type and Number:
WIPO Patent Application WO/2011/112362
Kind Code:
A3
Abstract:
Technologies are generally described for hyperthermia based treatment of diseased tissues using conductive particles. Conductive particles of known composition and size distribution may be implanted in diseased tissue and exposed to an alternating magnetic field, which may be tuned to the size of the metal particles to induce eddy currents producing heat in the implanted particles. As the temperature of the metal particles increases, their resistance also increases due to their positive temperature coefficient of resistivity. An antenna placed externally to the body near metal particles may be part of a tuned RF circuit and scanned for resonance. The change either in resonance frequency or circuit impedance may provide tuned feedback, which may be used to control the hyperthermia treatment.
