Author Description

Electrical impedance imaging is an imaging technique which has the capabilityof revealing the spatial distribution of the electrical impedance inside biologicaltissues. Classical electrical impedance imaging including Electrical ImpedanceTomography (EIT) typically has low resolution. Advances in electrical impedanceimaging typically involve methods that either increase image resolution or imagecontrast. This study investigates the possibility of the resolution improvement forelectrical impedance imaging using motion, and presents a novel high-resolution andcalibrated impedance imaging method called Scanning electrical Impedance Imaging(SII). SII uses an electrical probe held at a known voltage and scanned over a thinsample immersed in a conductive medium on a grounded conducting plane to obtainhigh-resolution calibrated impedance images of samples.
