Phase-based EPT is efficient method to measure in-vivo electrical conductivity distribution using only B1 phase information. To measure accurate conductivity value using phase-based EPT, spatial variation of the magnitude of transmit (B1+) and receive (B1-) field has to be negligible.However, when signal was received using multi-Rx, the spatial variation of B1- magnitude is non-negligible. In this study, we suggest a patient-individual coil combine method using two-stage optimization.
