It has been reported that combining ultrahigh field (UHF) with 3D imaging is beneficial for high-resolution imaging. Nevertheless, image quality may suffer from increased magnetic field inhomogeneity. Thus, we combined radiofrequency (RF) parallel transmission (pTx) with 3D simultaneous multi-slab (SMSlab) acquisition at 7T to get improved transmit field and optimal SNR efficiency concurrently. By simulation, it was proved that by using a 3-spoke RF pulses we could get 25% more uniform excitation magnitude than 2-spoke pulses (with almost the same RF peak power and identical pulse duration).
