In this work, we show high-resolution stacks of spirals on a tilted hexagonal grid. The new scheme provides flexibility in balancing readout and scan time, thereby allowing for high-quality images in a temporal resolution regime suitable for fMRI. 0.6 mm whole-brain coverage is achieved in below 5.
