Figure 1 RT3DE Quantification of LV Volume
Example of apical 4- and 2-chamber (top left and right, respectively) and short-axis (bottom left) cut planes obtained from a real-time 3-dimensional echocardiographic (RT3DE) dataset of 1 patient. Images are shown with semiautomatically traced endocardial contours that include endocardial trabeculae in the left ventricular (LV) cavity. Optimization of the boundaries in multiple planes results in a cast of the LV cavity (bottom right), from which LV volume is quantified by counting voxels inside the cast.
