A navigator-free motion correction method for Cartesian FSE is proposed for intermittent motion compensation. It first divides all shots into several motion-free groups, then estimates and corrects inter-group motion. In vivo imaging results show that this approach has decent performance in dealing with intermittent motion problems. Though only demonstrated with Cartesian acquisition, it is also applicable for non-Cartesian acquisitions, such as spiral and radial acquisitions.
