Abstract：This paper first summarized the achievements carried out by former researches and gave out their defects based on systematic study of EM imaging techniques. Then,put forward a new migration imaging technique of MT data using the improved finite difference method, which greatly increased the accuracy of the difference equation and the imaging resolution. Moreover, the paper also made further researches including the selecting of suitable resistivity background, joint imaging of two polarized modes, multi-parameters and second process imaging. Based on the calculation results of the model and the real observed MT data, the approach we provided has been testified as a more practical and effective measures for MT imaging.
