An automatic technique is presented for respiratory-gated 3D coronary MRA which acquires the data in the fastest possible time regardless of any changes in the breathing pattern (p = ns). No manual window is required as the technique, CLAWS, assumes all possible window combinations are relevant and acquires all data. Further, the scan may be aborted after an initial pass and an image reconstructed. CLAWS is shown to be significantly quicker than standard gating techniques with guaranteed image acquisition.
