    Abstract: A method includes applying a plurality of currents to a plurality of electrodes disposed on a surface surrounding an anatomical region in a subject. Further, the method includes measuring a plurality of voltages generated in response to the plurality of currents. The method also includes selecting a coarse-scale basis corresponding to a response function associated with the plurality of electrodes. Moreover, the method includes determining simultaneously an internal admittivity corresponding to the anatomical region and a contact impedance corresponding to the plurality of electrodes based on the plurality of voltages and the coarse-scale basis. The method also includes reconstructing the diagnostic image based on the internal admittivity.

    Abstract: A method and system for performing electrical impedance imaging of a subject of interest using a plurality of electrodes is provided. The method includes applying one or more determined current patterns to one or more electrodes of the plurality of electrodes. Further, the method includes determining a resultant voltage at at least one electrode of the one or more electrodes in response to the one or more determined current patterns. Moreover, the method includes estimating a change in a contact impedance for the at least one electrode of the one or more electrodes. Additionally, the method includes calculating a compensated voltage for the at least one electrode based on an estimated change in a corresponding contact impedance of the at least one electrode.
