A system for spatial impedance imaging includes a multi-layer coaxial probe for spatial impedance imaging. The multi-layer coaxial probe includes: an elongated core having a distal end and a proximal end; a first coating layer wrapping around the core; a set of alternating conductive and insulating coating layers on top of said first coating layer, wherein an Nth coating layer is shorter than an N-1th coating layer beneath it. The elongated core includes a needle or other suitable elongated member. |
