Zusammenfassung
This 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.
