Abstract
An imaging system includes determination of a first gradient-modulated offset-independent adiabaticity pulse associated with a first bandwidth and a first gradient strength, determination of a second gradient-modulated offset-independent adiabaticity pulse associated with a second bandwidth less than the first bandwidth and a second gradient strength less than the first gradient strength, determination of a third asymmetric adiabatic pulse based on the first gradient-modulated offset-independent adiabaticity pulse and the second gradient-modulated offset-independent adiabaticity pulse, and control of a radio frequency system and gradient system to apply the third asymmetric adiabatic pulse to patient tissue.
