Since the advent of EPI, numerous approaches have been suggested to enhance its resolution for high-resolution fMRI. Recently, several methods were demonstrated for fMRI with a sub-millimetre resolution. However, none of them can achieve such resolution with a full-FOV and, at the same time, with whole-brain coverage. This work aims to develop a novel imaging method based on EPIK in combination with readout-segmentation to achieve half-millimetre resolution with a full FOV. Here, under a typical fMRI constraint (TR of 3 s), the method was shown to provide 93 slices when further combined with the multi-band technique.
