Figure 2From: 2114 Temporal stability of the background velocity error shows potential for automated correction of regurgitant and shunt flow measurementsThe horizontal axis in each graph is the 40 days of repeated background error studies at the five offsets (-50...50 mm). AO = aortic plane. PA = main pulmonary artery plane. (a-c) Slope in background error (% of VENC per mm along FE axis). (d-f) Shift in background error at image centre (% of VENC).Back to article page
