A: Lambda2 based extracted isosurface of RV and LV quasi-donut shaped vortex rings identified during the early filling phase. B: Corresponding E-phase vortex positions relative to the cardiac geometry in a long axis view (ventricular and atrial boundaries are outlined in red). C: RV arch-shaped rings and LV elongated rings identified during the late filling phase. D: Corresponding A-phase vortex positions relative to the cardiac geometry in a long axis view.
