Fig. 1From: Use of self-gated radial cardiovascular magnetic resonance to detect and classify arrhythmias (atrial fibrillation and premature ventricular contraction)Example of respiratory modulation of cardiac motion-related signal. We can see that the joint motion-related signal (Image a) is modulated by the respiratory motion signal (Image b). However, valleys of the cardiac signal are still correctly detected (Image c, green stars) after the filtering stepBack to article page
