Introduction: Respiratory motion compensation in coronary artery MRI is challenging. Commonly, a pencil-beam navigator positioned on the right hemidiaphragm is used with a fixed slice tracking factor of 0.6 [1]. However, this scale factor varies among different patients [2, 3]. Respiratory selfgated navigator techniques have been introduced to directly measure the respiratory induced motion of heart [4]. The estimated motion is then utilized to retrospectively eliminate the motion artifacts [5… CONTINUE READING
