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.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
