Electrical conductivity and permittivity are fundamentally related to tissue properties, including cell volume fraction, ion & water distribution and cell membrane permeability. Imaging the electrical properties at the kilo-hertz range can be useful for diagnosis, functional imaging and electromagnetic modeling in biomedical engineering applications. It is theoretically possible to obtain conductivity maps utilizing the eddy current effect in MRI. In this lecture, we will introduce methods for conductivity mapping based on the eddy current effect and other principles.
