Three different designs of 2D and 3D spatially tailored RF waveforms are demonstrated and their performance evaluated in single-channel phantom imaging and in simulation of 8-channel array incorporating experimental B1 field profiles. The result suggested that accelerated multidimensional RF pulses can excite useful B1 profiles in clinically relevant excitation time.
