ABSTRACT:
A method of practicing electrical impedance tomography produces three-dimensional images of a body. First, one applies certain special current patterns to the body through an array of electrodes attached to the surface. For each current pattern, one measures the voltage at each electrode, thus obtaining a corresponding pattern of voltages. These data are then used in a certain special reconstruction process, which enables a full three-dimensional reconstruction to be done in a short time. The result is a display of an approximation to the electric conductivity and/or electric permittivity in the interior of the body.
