System for examining tissue according to the dielectric properties thereof

process for examining tissue in order to it according to the dielectric properties to differentiate the examined tissue from other tissue, comprising: Such Applying an electric pulse through a probe to the to be examined Tissue that the probe is an electrical fringe field in the examined Tissue produces and generates one of them re-radiated pulse, wherein an insignificant radiation in other tissues or biological body penetrates near the examined tissue; Detecting the reflected electrical pulse; and comparing the electrical characteristics the reflected electrical pulse with respect to the applied electric pulse, to provide an indication of the dielectric properties of the examined provide tissue.
