Abstract:
Magnetic induction tomography (MIT) is a kind of contactless and noninvasive method to reconstruct the conductivity distribution in a cross-section. We developed a data acquisition system with one exciting coil and 15 measuring coils. By rotating the object placing on a circle plate, the 16*15 measurement data were obtained. The Newton-Raphson algorithm was applied to reconstruct the conductivity distribution. To the conductivity perturbation objects in air field, we made the difference images of MIT. The images were able to demonstrate the location of the objects and identify the conductivity difference between 0.84 S/m and 1.26 S/m, which are in the range of biological tissue.
