Magnetic resonance electrical impedance tomography
(MREIT) is an emerging method to visualize static
conductivity and/or current density images at low
frequencies (below 1 kHz). Diffusion tensor imaging
(DTI) measures the intrinsic three-dimensional diffusion
property of water molecules within the human body. The
effective macroscopic anisotropic tensor model implies
the linear relationship between the effective electrical
conductivity tensor and the water diffusion tensor. By
assigning the linear relation, we propose a novel method
to visualize the absolute anisotropic conductivity
tensor map by combining DTI and MREIT techniques without
any referred extracellular conductivity and diffusivity
information.
