Weighted polynomial fitting method was proposed to resolve boundary artifact and noise amplification of Electrical Property Tomography. Weighted polynomial fitting method employs T1/T2 tissue contrast as prior information under assumption that pixels with similar magnitude intensity have similar conductivity. However, for non-simply connected structures make the fitting inaccurate. Therefore, in this study, we propose a modified weighted polynomial fitting technique including spatial constraint.
