Caption

(A) Water molecules exhibit charge offsets in an alternating electric field. (B) Brain lesions such as bleeding foci, cerebral edema, and infarcts alter electrical impedance, which can be detected via electrode arrays. (C) Signal processing using a digital mixed signal processing system (DMSPS) transforms amplitude and phase features into clinically relevant parameters, including disturbance coefficient, edema coefficient, and intracranial pressure.
