title: The acquisition hardware system with direct digital synthesis and filtered back-projection imaging in electrical impedance tomography.
abstract: Electrical impedance tomography is a new imaging modality that produces images by computing electrical conductivity within the body. This paper presents a basic acquisition hardware system of Electrical Impedance Tomography with direct digital synthesis (DDS), which is used for studying the human head electrical property. The filtered back-projection algorithm is used for image reconstruction.
