Figure 1.
Color Doppler spatiotemporal image correlation volume dataset of normal fetal heart, showing nine cardiac diagnostic planes displayed automatically in single template through color Doppler Fetal Intelligent Navigation Echocardiography (see Videoclip S2). Color Doppler signals are displayed in systole. The unique feature of automatic labeling (through intelligent navigation) of each plane, anatomical structures, fetal left and right sides and cranial and caudal ends is shown. Labeling is distinctive because it stays with corresponding anatomical structures, even as image is increased in size (zoom). A, transverse aortic arch; Ao, aorta; Desc., descending; IVC, inferior vena cava; LA, left atrium; LV, left ventricle; P, pulmonary artery; PA, pulmonary artery; RA, right atrium; RV, right ventricle; RVOT, right ventricular outflow tract; S, superior vena cava; SVC, superior vena cava; Trans., transverse.
