On the measurement of conductivity distribution of the human head using magnetic resonance electrical impedance tomography.

We have applied the magnetic resonance electrical impedance imaging (MREIT) technique to image the three-dimensional (3D) conductivity distribution of the human head. Computer simulations were carried out on a tradition four-sphere head model to test the feasibility of imaging conductivity distribution of the human head. The present results show that the 3D head conductivity distribution could be well reconstructed using MREIT.
