In this work, calculated eigenmodes of a 20-channel array coil (Tic-Tac-Toe based) were used to optimize B1+ field. An exhaustive search was used to go through all possible eigenmodes combinations. Field uniformity, field efficiency and SAR are used to evaluate the optimized cases. Multi-level/row coil with eigenmode optimization methods could facilitate fields uniformity in the entire brain including the cerebellum region. High quality 3D MPRAGE could be acquired.
