Stroke has two forms: bleeding in the brain (hemorrhagic), or a blood clot preventing blood flow (ischemic). A portable device for detecting the type of stroke would be a life-saver. Now ischemia lowers the conductivity of brain tissue, while hemorrhage raises it. EIT is an imaging method for recovering internal electric conductivity from boundary measurements. Therefore, EIT offers a promising approach for cost-effective stroke classification, although the resistive skull makes the inverse problem very difficult.
