Abstract

Three dimensional spatial selective RF pulse of practical length has been demonstrated using parallel transmission technique in Magnetic Resonance Imaging. Currently, spoke trajectory, which is a set of parallel k-space straight lines, is widely used for 3-D slab excitation to achieve sharp slice profile and a uniform or smoothly varying in-plane profile. The better control of in-plane profile mainly comes from an increased number of spokes. In this paper, we proposed three types of modified spoke trajectories for the 3-D tailored RF pulse design which traverse k-space more efficiently. Simulations are used to characterize the proposed trajectories.
