Cardiac motion frozen processing separately in each respiratory phase (contoured red bins) to end-diastole phase (solid red bins). 2. Respiratory motion frozen processing of cardiac end-diastole bins (contoured blue bins) to end-inspiration bin (solid blue bin). 3. Final motion-free image in end-diastole/end-inspiration (solid green bin). ECG = electrocardiography. Reproduced from research originally published in JNM.
