In the present study, we investigate the feasibility of a complex B1 mapping technology using a multi-channel transceiver coil at ultrahigh field for the purpose of imaging electrical properties of realistic human head by computer simulation. Complex B1 mapping and electrical properties reconstruction were carried out on both normal symmetric head and pathological asymmetric head with a tumor at 7 T and 9.4 T. The simulation results show that on realistic asymmetric geometry, the method performs equally well as on symmetric geometry and suggest its practical value for diagnostic purpose and SAR calculation at UHF.
