Abstract :
We describe a technique for noninvasive conductivity estimation of the human head tissues in vivo. It is based on the bounded electrical impedance tomography (bEIT) measurements procedure and realistically shaped high-resolution finite difference model (FDM) of the human head geometry composed from the subject specific co-registered CT and MRI. The first experimental results with two subjects demonstrate feasibility of such technology.
