Abstract

Tomography is a technique that can create an image showing the internal structure of an object, preferably without causing any damage. Electrical tomography includes electrical impedance tomography (EIT), electrical capacitance tomography (ECT), and magnetic induction tomography (MIT). MIT's low-cost and noninvasive features can offer great excitement and potential to address many challenging problems that exist in the current industrial/medical applications. Coils are used as transmitters and receivers in MIT. When the MIT forward model is simulated, the inverse solver will be used to obtain the reconstructed image based on the forward model. However, in MIT, because of the dispersed nature of the electromagnetic field, the change in conductivity cannot be localized anymore and can cause signal perturbation on any measurement set, which makes the MIT model more complicated. MIT is a very useful imaging tool that has great potential to be applied in many different areas, in both industrial and medical applications.
