Abstract

We have developed a novel magnetic resonance electrical impedance tomography (MREIT) algorithm - current density reconstruction MREIT algorithm - for noninvasive imaging of electrical impedance distribution of a biological system. The newly proposed algorithm uses the inverse of Biot-Savart law to reconstruct the current density distribution from one component of magnetic flux density, and then uses a modified J-substitution algorithm to reconstruct the conductivity images. Computer simulations were conducted to evaluate the performance of the proposed MREIT algorithm for breast cancer imaging. The simulation results are highly promising and suggest the proposed approach may become a useful method for noninvasive impedance imaging.
