Parallel transmit hybrid pulse design for controlled on‐resonance magnetization transfer in <scp><i>R</i><sub>1</sub></scp> mapping at 7T
The proposed hybrid design homogenizes on-resonance MT effects while homogenizing the flip angle distribution, with only a small detriment in the latter compared to a pulse that just homogenizes flip angle.
