Estimation of brain anisotropic conductivity has a
potential in analysis of interactions between
electromagnetic fields and biological systems, such as
prediction of current pathway in tDCS and DBS. In this
study, we reconstruct anisotropic conductivity
distribution of canine brain by combing information from
the DTI and MREIT imaging. Since the MREIT technique is
used for visualizing high-resolution isotropic
conductivity at low frequency. Combing the measured
water self-diffusion from DTI and z-component of
magnetic flux density from MREIT, it is possible to
obtain effective-conductivity-to-diffusivity ratio (ECDR)
in every voxels which provides precise information for
brain anisotropy comparing to global scaling factor.
