Figure 2

Cardiac imaging reconstructions with automatic binning and SHARP reconstruction after 15 single-shot SPGR acquisitions in free breathing (breath-hold and free-breathing scan durations were approximately 6 s). A significant visual improvement as well as a reduction of artifacts is seen when correcting for the motion using respiratory binning, compared to motion compensation only (arrows). The time needed to run the motion-compensated reconstruction for 15 shots of matrix size equal to 192 x 256 with an 18-ch cardiac coil was about 4 min 52 seconds and is reduced to 1 min 35 seconds when the data are clustered into 5 bins.
