Abstract
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.

-
a multi-layer coaxial probe for spatial impedance imaging, comprising; 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; wherein each coating layer begins at a first distance from the proximal end, and ends at a second distance from the distal end;
wherein values of the first distance and the second distance increase for external coating layers relative to internal coating layers. - View Dependent Claims (48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66)
