We have developed the Global-to-Local Tandem Method to detect the coronary stationary period for WH MRCA, in which the coronary stationary period is roughly analyzed by the global method and then more precisely analyzed by the local method. We have also conducted clinical feasibility studies. Results suggest that The Global-to-Local Tandem Method can robustly detect the coronary artery stationary period in WH MRCA (Whole Heart Magnetic Resonance Coronary Angiography). It is therefore concluded that this method should prove to be very useful for clinical WH MRCA examinations.
