The purpose of this work was to design and implement constant adiabaticity gradient
modulated pulses that have improved slice profiles and reduced artifacts for spectroscopic
imaging on 3T clinical scanners equipped with standard hardware. The newly proposed
pulses were designed using the gradient offset independent adiabaticity (GOIA, Tannus and
Garwood [13]) method using WURST modulation for RF and gradient waveforms. The GOIA-
WURST pulses were compared with GOIA-HSn (GOIA based on nth-order hyperbolic …
