Claim One:
1. A method for producing a motion-corrected image using a magnetic resonance imaging (MRI) system, the steps of the method comprising: a) acquiring data with the MRI system by sampling k-space as a series of blades, each blade containing a plurality of parallel linear trajectories in k-space, wherein the blades are rotated with respect to each other and include a total of N blades; b) selecting a pair of blades including a first blade and a second blade from the total of N blades; c) forming an equation relating a relative shift value that maximizes a correlation value between the first blade and the second blade; d) repeating steps b)-cd) for a majority of N(N−1)/2 pairs of blades in the acquired data; e) solving the equations formed from the repetition of step c) to create motion-corrected blades for the N(N−1)/2 pairs of blades in the acquired data; and f) reconstructing an image from the motion-corrected blades.
