In our work, we propose a new method to retrieve electrical properties of tissues when the half phase assumption holds, termed Localized Electrical Property Retrieval (LEPR). For this method, only surface integration is needed rather than a volume one. Furthermore, the surface integrals can be chosen so that only B1+ or B1- is needed, meaning it does not require the z-component of the magnetic field, which is similar to electric properties tomography (EPT). In this abstract, the theory of LEPR is presented in detail. Under the tested simulation data where ground-truth is known, the LEPR maps out-perform EPT.
