Among the advantages of the Transmit-SENSE method is the ability to facilitate short low SAR excitation pulses with excellent flip-angle homogeneity at high field. In this framework, large tip angle pulses are of particular interest as they could provide a viable alternative to the SAR-demanding adiabatic solutions. In this abstract, we demonstrate the kT-points method in the MP-RAGE sequence for high-resolution T1-weighted brain imaging at 7 Tesla, omitting adiabatic pulses by introducing the kT-points-based inversion pulse design.
