Abstract

A method for characterizing a tissue, the method includes: inserting, in a sequential manner, a biopsy probe to the tissue at multiple locations of a tissue region of interest, while monitoring the insertion to provide location information; wherein the locations are determined in view of tissue information indicative of a tissue region of interest; performing electrical measurements at each of the multiple locations utilizing at least one biopsy probe electrode to provide electrical measurement information; taking a tissue biopsy at one or more locations of the multiple locations; and generating impedance information reflecting a spatial distribution of electrical impedance of the tissue in response to electrical measurement information and location information obtained from the multiple locations.
