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.
