Abstract
A coil for facilitating magnetic induction tomography imaging of a specimen, such as a human tissue specimen, using a single coil is provided. The coil can include a plurality of concentric conductive circular loops. The concentric conductive loops can be connected in series with connection traces without allowing the connection traces to distort the fields produced by the plurality of concentric conductive circular loops. The plurality of concentric conductive loops can be arranged in multiple planes (e.g. on a multilayer printed circuit board) as a two layer stack. The spacing between the planes or the plane separation distance can be selected such that mathematically the plurality of conductive loops can be treated as being located in a common plane for purposes of a quantitative analytical model used for magnetic induction tomography imaging.
