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.
