An adiabatic pulse has been developed to accomplish uniform slice- selective excitation with a spatially inhomogeneous B1. This new pulse can generate a uniform, arbitrary flip angle that is determined by four adjustable phase shifts in the pulse. Self-refocused slice selection is achieved by modulating a B0 gradient in concert with the pulse frequency (or phase) modulation. B1-compensated, self-refocused slice selection is demonstrated in computer simulations and phantom experiments using a surface transmitter/receiver coil. This adiabatic pulse can provide optimal performance in multislice MRI and localized spectroscopy when transmitting with an inhomogeneous B1.
