Reconstruction Method of Magnetic Induction Tomography based on Filter Back-Projection
Magnetic Induction Tomography (MIT) is a new method contact-less method of conductivity tomography, and it gets the conductivity of biology based on electromagnetic detecting. In the excitation of excitation coil the biologic tissue inspires perturbation, which could be measured by receiver coils. For the questions of MIT system, a new multi-channel magnetic induction imaging system model with rotatable platform was proposed in this paper, and a reconstruction method based on filter back-projection was presented. First, the detected data was supplemented to a round, and then was interpolated in the reconstruction process. At last the reconstructed image was got. Experiment results demonstrate that this model is an effective model in magnetic detecting and the conductivity of different objects can be distinguished effectively, and the conductivity in the detecting area could be imaging by the model and reconstruction method.
