Abstract
The present invention relates to probes, systems, and methods for tissue characterization by its dielectric properties, wherein a physical feature of the probe is designed to define and delimit a tissue volume, at a tissue edge, where characterization takes place. Thus, the probe for tissue-edge characterization comprises: a first inner conductor, which comprises: proximal and distal ends, with respect to a tissue edge, along an x-axis; a first sharp edge, inherently associated with the proximal end; at least one feature, issuing from the first inner conductor, substantially at the proximal end, for forming at least one additional sharp edge, operative to enhance localized electrical fringe fields in the tissue, within a generally predefined tissue volume, at the tissue edge, the tissue volume being generally defined by physical parameters associated with the at least one feature; and a dielectric material, which encloses the conductor, in the y-z planes.
