Original Abstract

This article discusses two-dimensional reconstruction of the internal conductivity distribution for a human head tissues imaging and for the determination of corresponding brain tissue changes with the help of the Magnetic Resonance Electrical Impedance Tomography (MREIT) method. MREIT is a bio-imaging modality providing cross-sectional conductivity images with a high spatial resolution from measurements of internal magnetic flux density produced by externally injected currents. The new algorithm for the image conductivity reconstruction, which uses the internal current vector information with respect to corresponding boundary conditions, was developed. This algorithm was applied to the several computer simulations to demonstrate the feasibility. Obtained conductivity reconstruction results are presented and the reached experience is discussed. The future research direction is also proposed.
