Local correlation and dispersion based measures have been introduced to reliably reflect the improvement in dynamic 4D MRI data tissue alignment post motion correction. These measures can be used as part of motion correction workflow and provide means for quantifying the efficacy of motion correction schemes in dynamic data across different anatomies and clinical sites.
