Volumetric self-navigators
constructed from a subset of partitions during repeated 3D-EPI acquisitions are
able to accurately detect and correct motion in real time, without additional
pulses or hardware, enabling motion-robust 3D-EPI functional MRI.

(a) before motion occurred (reference volume), (b) when motion occurred, and
(c) the next volume after motion occurred.
