Magnetic Resonance Electrical Property Tomography (MREPT) is recently introduced to noninvasively image the distribution of electric conductivity and permittivity in the human body at the Larmor frequency. Over homogeneous regions, the relationship between the electric properties and magnetic fields can be simplified as a Helmholtz equation of B1+. In this work, the methods using B1+ maps generated by EM simulations on numerical phantoms with two tissues were proposed to investigate and evaluate how the error in the conductivity estimates using the Helmholtz equation of B1+ is related to the SNR of B1+ and the size of the tissue.
