Performance evaluation using retrospective sampling on Cartesian data using 16 radial rays/frame: We show two example frames, the image time profile along the dotted line in (a), and the corresponding difference images for all the methods. The difference images are scaled up by a factor of five for better visualization. The image time frame locations in the first two rows are depicted by the dotted lines in the time profile of (a). The compressed sensing (CS) reconstructions exhibit considerable motion artifacts and temporal blurring (see arrows), while the proposed deformation corrected CS images (DC-CS) are robust to these compromises. The last row depicts that the proposed algorithm was capable of estimating and correcting most of the deformation due to inter frame motion.
