Adiabatic pulses are widely used for spatial localization in MR spectroscopy because of their high immunity to RF inhomogeneity and excellent slice profiles. Since non-rectangular volume is often preferred in localized spectroscopy, here we optimized and experimentally tested a scheme that uses a time-varying gradient orthogonal to a stationary slice-selection gradient to generate slices with nonparallel boundaries.
