A
new method which employs the SLR algorithm to generate velocity selective
inversion pulse is presented and a design example is shown. Simulation
results demonstrate that the slice profile of the designed inversion pulse is
very smooth and that the pulse has good resistance to B1 inhomogeneity.
Phantom studies verified the frequency selectivity and the velocity
selectivity of the pulse. All results imply that the pulse is potentially
suitable for use as a tagging pulse in VSASL. The design method enables the
pulse designer to explicitly trade off among important parameters such as
slice thickness, pulse duration and pass-band ripple.
