More Information
Summary:An efficient navigator method is presented that substantially increases the scan efficiency while maintaining the motion suppression effectiveness in magnetic resonance imaging. The method is achieved by simultaneously acquiring different image volumes at different motion states of the subject being scanned. A scheduling algorithm is used to assign volumes to position bins of a motion histogram of the subject. The motion histogram is periodically updated and the volumes are reassigned to position bins.
