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.
