title: Some physical results from an impedance camera.
abstract: We discuss some physical results from an impedance camera. We placed agar blocks of various resistivities and sizes in saline. We showed that when the agar block was small or close in resistivity to the saline solution, we were unable to reconstruct it. We attempted to reconstruct an image of a fist, but were unable to achieve this due to current flowing in the arm. We concluded that three-dimensional analysis may be needed, along with more sensitive reconstruction algorithms and measurements.
