Patent ID: 7725151

Claim:
A method for detection of dielectric anomalies at the surface of human or animal organs, including the skin, other tissues and cells, comprising: (a) applying electromagnetic energy through an array comprising a plurality of closely-spaced coaxial near-field probes each having a center conductor and a coaxial shield, each center conductor terminated in a tip that is substantially flat and flush with adjacent tips to provide a flat surface positionable substantially in contact with the surface using electrical pulses or continuous-wave excitation with one or a multiplicity of frequencies having content in the range of 10 MHz to 300 GHz at an object positioned on the surface of a human or animal organ; (b) acquiring the reflection or transmission coefficient spectra or both from the object; and (c) reconstructing from the acquired reflection or transmission coefficient spectra an image of the object at antenna sample distances shorter than the wavelength of the electromagnetic energy.
