Automatic Detection of Quiescent Cardiac Phases using Navigator Echoes with Adjacent Complex Correlation Algorithm

PURPOSE In many cardiac imaging applications, the accurate detection of the systolic and diastolic quiescent periods is critical in obtaining optimal image quality and is usually determined by observing cardiac motion in a CINE acquisition. This complicates the cardiac exam procedure and does not adapt to heart rate variations throughout the exam. In this study, we investigated the feasibility of an automatic detection technique that could detect both cardiac and respiratory motion, and could be adapted to various cardiac sequences.
