Advance in study of electric impedance tomography of human head tissues / 国际生物医学工程杂志

ABSTRACT

Brain diseases and brain activities are always accompanied by the conductivity changes of the head tissues.Electrical impedance imaging (EIT) is used in diagnosing brain diseases and monitoring brain functional activities.The basic concept of non-invasive electrical impedance imaging on human head and its aplication potential are introduced in this paper.Several EIT techniques based on magnetic field measurement are introduced.The existing problems and foreground of the related research are also discussed.
