To homogenize signals 7 Tesla MRI reliably and fast, a pTx pulse design process was established. Trajectory, energy regularisation parameter and universal pulse shapes were calculated by solving global optimization problems using a dataset of 12 subjects (B1+ profiles, B0, VOP). Pulse shaping is done online using the actual subject‘s data acquired during the sequence preparation phase which lasts about 90s. A fitting curve for SED is also provided which, combined with online calculated SED values, aims to use the full amount of tolerable SAR. Compared with the CP-Mode, the NRMSE could be substantially improved for all 36 volunteers.
