Physical and simulated phantom objects. (A) Experimental phantom: top and oblique views of the gel phantom, and (B) Three-dimensional finite-element model (FEM) mesh of the conductivity phantom (σ = 0.71 Sm−1) showing an insulating cylindrical inclusion placed in the middle of the phantom. Four carbon-hydrogel electrodes were attached on the perimeter of the octagonal surface to inject electric currents into the phantom.
