Imaging of the head using induced current impedance tomography

The use of induced current electrical impedance imaging to detect epileptic foci has been simulated. The simulation uses a three dimensional finite element model to determine the sensitivity required of the measuring system in order to detect an epileptic focus represented as a cube of side 10 mm with a 10% change of conductivity. It is shown that the system can image foci near the edge of the region, but is less successful near the centre.
