Estimating and eliminating the excitation errors in bipolar gradient composite excitations caused by radiofrequency‐gradient delay: Example of bipolar spokes pulses in parallel transmission
PURPOSE: To eliminate a slice‐position–dependent excitation error commonly observed in bipolar‐gradient composite excitations such as spokes pulses in parallel transmission. THEORY AND METHODS: An undesired timing delay between subpulses in the composite pulse and their bipolar slice‐selective gradi...
