high RF power deposition which particularly limits their use at high
resolutions and high field strengths. In this work, TRAPS and fixed SAR Power Independent
of Number of Slices (PINS)-refocusing pulses were used to reduce the power deposition. Multiband excitation pulses were added to enable arbitrary user-defined slice
orientations, with the added benefit of accelerating the acquisition due to the
simultaneous excitation of multiple slices. Good image quality was obtained for a MB4-HASTE protocols with 3.1 and 1.1 mm resolution, and a whole-brain MB6-HASTE protocol with 1.1 mm resolution.
