  • Title: Distinguishability in impedance imaging.
    Author: Cheney M, Isaacson D.
    Journal: IEEE Trans Biomed Eng; 1992 Aug; 39(8):852-60. PubMed ID: 1505998.
    Abstract:
    Impedance imaging systems apply currents to the surface of a body, measure the induced voltages on the surface, and from this information, reconstruct an approximation to the electrical conductivity in the interior. This paper gives a detailed discussion of several ways to measure the ability of such a system to distinguish between two different conductivity distributions. The subtle differences between these related measures are discussed, and examples are provided to show that these different measures can give rise to different answers to various practical questions about system design.
