Tingting Shao1, Nikolai I. Avdievich1, and Anke Henning1,2
work presents experimental results of 3D volumetric parallel excitation at a 9.4T
human whole-body MRI scanner. The approach and concept of a “trajectory
container” is adopted to match practical considerations. The “trajectory
container” is used to shape the k space trajectory and restrict it to a limited traversing
area in the k space and therefore to constrain the pulse duration. A simplified
and direct way of the definition of the “trajectory container” is proposed and
verified with promising experimental results.
