Magnetic resonance electrical properties tomography (MREPT) is a technique which estimates conductivity and permittivity by measuring B1 information. Previous MREPT assumed that electrical properties are locally homogeneous so this assumption incurred the "Boundary Artifact". Lees proposed method reduces boundary artifact by iterative process. However, this method was verified just for simulation data with high SNR condition. To verify the practical applicability of this method, in this study, the iterative boundary artifact reduction algorithm is implemented for a phantom experiment.
