Method of image reconstruction in electrical impedance tomography

摘要

Reconstruction of the image in the electrical impedance tomography to determine the non-uniformity of the material, in which way: contacts (1) are placed on the edge of the material being tested: these forces the flow of electricity: and are read from them through the wires (2) connected between the contacts and the data acquisition system (4);characterised by: a conformal representation representing the conversion of the disc to the shape of the area under examination is defined: there are many hole positions in the area under examination; a radius of holes in the specified positions is determined, processing the read-out voltages (1) using flow theory in multiple systems, using a processor (5) connected to the data acquisition system (4);and the specified hole radius is displayed by means of a visualisation system (6),by transforming the positions and radii of the holes into the area under examination using a conformant representation.
