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.
