Abstract

In summary, we have pursued, since 2004, the electrical impedance imaging of head-brain tissue conductivity profiles by means of the MREIT. We have developed several MREIT algorithms for head-brain imaging and demonstrated the feasibility and merits of imaging head-brain conductivity profiles by means of MREIT in a computational setting. Although further development is needed to apply MREIT in a clinical setting, experimental evaluation is needed to fully assess the utility and applicability of the developed MREIT algorithms. Our work suggests that MREIT brain imaging deserves further investigation and may become a useful tool in imaging conductivity distributions of the brain and head.
