Abstract
A hydrogel phantom is herein described. The hydrogel phantom includes a plurality of adjacently disposed hydrogel elements. A first one of the hydrogel elements has a first electrical impedance and a second one of the hydrogel elements has a second impedance. The first impedance is different from the second impedance.
