A novel automatic quiescent cardiac phase detection technique is presented. An adjacent complex correlation algorithm was used to analyse the cardiac navigator echoes acquired continously throughout the cardiac cycle. We have shown the feasibility of detecting the timing and duration of the quiescent phases using this technique. Respiratory motion can also be detected effectively. This technique could be applied to various cardiac pulse sequences for automatic and adaptive triggering, and therefore, increase the robustness of cardiac imaging.
