We present a retrospective rigid motion correction and reconstruction scheme for brain MRI with the aid of structural priors. The proposed framework is designed to be applied to a clinical protocol including multiple scans for multiple contrasts, of which some scans are corrupted due to motion during the acquisitions, but at least one is uncorrupted and exploited as an additional prior. We envision a practical workflow that can easily fit into the existing clinical practice without the need for changing the MRI acquisition protocols.
