A simulation study on induced current magnetic resonance electrical impedance tomography of anisotropic brain tissues

An induced current magnetic resonance electrical conductivity tomography (IC-MREIT) algorithm was developed to reconstruct the anisotropic electrical conductivity distribution of the human brain. The IC-MREIT J-substitution algorithm was adopted to reconstruct isotropic conductivity which was used as the initial information to reconstruct the anisotropic conductivity distribution iteratively. The simulation results conducted on a three-sphere head model suggest that the proposed algorithm can reconstruct the anisotropic conductivity distribution of brain tissues with good accuracy and is robust to measurement noise.
