A self-navigating technique designed to detect motion in segmented sequences is disclosed. Certain embodiments compare a plurality of segments containing adjacent sets of k-space lines and produce an aliased error function which corresponds to a correlation of the segments. A global shift of the aliased error function may indicate the presence of in-plane rigid-body translation while other types of motion are evident in the dispersion or breadth of the error function. Some embodiments may then replace motion corrupted data with reacquired data. Further, some embodiments may correct or remove corrupted data retrospectively.
