Figure 8 (A) Individual cut plane of the 3-dimensional (3D) data set (5-chamber view). Fine structures like the atrial septum, leaflets of the mitral valve (MV), and cusps of the aortic valve (AV) are spatially well resolved. The 3D data set comprises multiple parallel cut planes. (B) Left oblique view of ventricles and atria. Interatrial (IAS) and interventricular septum (IVS) can be recognized as well as the free wall of the right atrium (RA) and right ventricle (RV). The MV is closed; the view is directed toward the left ventricular outflow tract. (C) View through the opened AV. Further, the view passes through the RA to the IAS. The closed MV can be seen in the anterior area of the left atrium (LA). (D) Top view of the atria, the atrioventricular valves, and the AV. The view passes through the LA to the IAS. Anterior and posterior mitral leaflets are visible. The fine edges of the cusps are well-resolved in the area of the AV; the sinus of Valsalva are visible in the 3D image. LV = left ventricle; TV = tricuspid valve.
