Robust time-shifted spoke pulse design in the presence of large B0 variations with simultaneous mitigation for through-plane dephasing, B1+ effects and the specific absorption rate using parallel transmission
PURPOSE: We design parallel transmission (pTx) spokes pulses with time-shifted sub-pulse profiles for joint mitigation of intensity variations due to B1+ effects, signal loss due to through-plane dephasing and the specific absorption rate (SAR) at 7 Tesla. METHODS: We derive a slice-averaged small t...
