A framework for retrospectively motion corrected reconstruction of multislice multishot MRI in the presence of 3D rigid motion is developed. The method is able to cope both with within-plane and through-plane motion by estimating the motion states corresponding to the acquired shots and slices. It has been applied to 478 T1 and T2 newborn brain studies, including many severely motion corrupted examples, for which consistent structures have been recovered in more than 96% of cases. Due to its robustness and flexibility, our technique has wide potential application for both clinical and research examinations.
