The elctrical properties of realistic head model based on eletrical impedance tomography

Electrical impedance tomograghy (EIT) is relatively new imaging modality based on electrical property of human or animal tissues. This paper presented the electrical properties of four-shell concentric circular head model and 2D realistic head model which have been reconstructed from the MRI head picture based on EIT technique. This work were expected to provide the basis of resolving EIT inverse problem and reconstructing image of head electrical conductivity, and is of significance for the further research on electrical property of head.
