Typical clinical MR examinations are composed of several sets of scans to acquire images with different contrast, such as T1w, T2w and DWI. Currently, the acquisition and reconstruction of these images are kept separate. Since the same subject is scanned in the same system using the same RF coil, there is sharable common information among these images. It is shown that the data correlation among channels from motion insensitive sequence can be shared for a motion compensation. Preliminary results with in-vivo data sets show that rigid motion artifacts can be corrected using sharable information from images with different contrast.
