Abstract: In order to obtain good effect of image reconstruction of ECT, this paper proposes an ECT image imaging method of improve Landweber algorithm based on data correlation analysis. Using Maxwell simulation software, the method first determines the division of the micro element, then calculates the capacitance of each element as a high dielectric constant, and makes a correlation analysis between each capacitance values and the measured capacitance values, a correlation coefficient can be obtained. We can combine the correlation coefficient with the sensitive field, and obtain a new sensitive field by using the soft field characteristics of the sensitive field. Combine the new sensitive field with the Landweber algorithm to improved image, we can get better imaging of position image.
