Electrical impedance tomography (EIT) is a noninvasive technique that permits estimation of resistivity within a subject by reconstructing from boundary measurements. The head electrical properties based on EIT technology have been studied by many authors and in most of this work the realistic head model has been considered without contact impedance between the electrodes and the scalp. It is interesting...
Stimulus evoked electromyography is currently used during surgery to prevent nerve root injury during iliosacral screw insertion. In order to evaluate the importance of anode location in this procedure, a three dimensional finite element model was constructed from computed tomography data to evaluate the effectiveness of five electrode locations. Three anode locations (CASIS, dorsal midline and ventral...
