Electrical Impedance Tomography Imaging And Application

Electrical impedance tomography(EIT)is a novelty imaging technique. It reconstructs the internal impedance distribution by the electrical parameter measurements made on the electrodes placed on the surface of the organism. Since the organism has different impedance distribution under the different condition, the reconstructed image can reflect the state of the organism and provides useful information for medical diagnosis. The application of this technique is also a developing research area, for example, the image fuse is to promote its clinic application, and the three-dimensional is for its farther application.This paper analysis the EIT from its theory, combine some classical arithmetic, educe the arithmetic which based on the Isopotential lines reverse projection, combine the animal experiment to prove its effect, and we basis the particularity of EIT , we use VC to realization some explores for the clinic application and we get the good effect, after go deep into the hardware system, we bring forward some key problems to improve this system.
