Abstract:
A method of detecting the onset of biological tissue disease comprising the method of:a) designating a target tissue area for electromagnetic irradiation;b) determining expected tissue dielectric values for the designated target tissue area at frequencies above and below the relaxation frequency of the designated target tissue;c) providing a multiple frequency radiation emitting and receiving system having emission means comprising a plurality of emitter-receiver locations, receiving means comprising a plurality of emitter-receiver locations, and signal analysis means;d) irradiating the target tissue area with the multiple frequency radiation emitted from a plurality of emitter-receiver locations, said multiple frequency radiation being suitable for discreet detection of intracellular, extracellular and cell membrane resistances;e) receiving the radiation from the irradiated target tissue area with the microwave receiving means; andf) analyzing the received radiation with the signal analysis means to obtain observed tissue dielectric values an comparing the observed tissue dielectric values for a desired range of frequencies best correlating to the target tissue with the expected tissue dielectric values to determine a change in the physiologic state of the target tissue indicative of an onset of tissue disease.
