A technique of extracting cardiac and respiratory motion cycles by use of projection data is proposed and studied. These extracted cardiac and respiratory motion cycles are applied to the cine imaging of heart and motion artifact reduction in abdominal imaging instead of the conventional ECG gating devices. The basic concepts and their applications are discussed, Experimental results on human volunteers obtained with the KAIS 2.0‐T whole‐body NMR imaging system together with the pulse sequences used for the experiments are presented.
