Body imaging at 7T suffiers from flip angle (FA) inhomogeneities caused by the shorter, field strength dependent excitation wavelength. Parallel transmission (pTx) methods can counteract these inhomogeneities, but subject-specific solutions require long calibration times for mapping the channel-wise transmit (B+1) fields. In this work, we investigate the possibility of accelerating the B+1 -mapping via undersampling and compare our approach to calibrationless universal pTx approaches.
