Abstract
Systems, methods, and apparatus for magnetic induction tomography imaging of specimens, such as human tissue specimens, using a single coil are provided. A plurality of coil property measurements can be obtained using the single coil at a plurality of discrete locations relative to the specimen. The single coil can be designed to be relatively easy to be placed in many different positions/orientations relative to the specimen. A three-dimensional electromagnetic property map, such as a three-dimensional conductivity map or a three-dimensional permittivity map, can be generated from the plurality of coil property measurements obtained using the single coil by accessing a model correlating coil property measurements obtained by the single coil with an electromagnetic property distribution of the specimen.
