Correlations between adjacent K-Space lines can be used to detect non-rigid body motion or motion that occurs out of plane. The cross correlation between two adjacent sets of equally spaced K-Space lines is a set of equally spaced delta functions convolved with an error function. The error function is a result of correlation errors between adjacent sets of lines. These errors are present even when there is no motion of any kind, however, as the amount of data corruption increases the error function broadens. As a result, a measure of the relative sharpness of the error function provides a measure of data corruption.
