Automatic 3D echocardiographic segmentation is feasible; hypothesis-generating and requires prospective validation before clinical adoption.
A novel fully automatic 3-D echocardiographic segmentation framework enables fast (approx. 1 second) and accurate quantification of left ventricular volumes, improving upon previous manual initialization methods.
Barbosa et al. (2012) studied this question. Automatic 3-D echocardiographic segmentation using B-spline explicit active surfaces vs. Manual initialization was evaluated on Computation time and accuracy for quantification of left ventricular volumetric indices. An automatic 3-D echocardiographic segmentation framework provided fast and accurate left ventricular volumetric quantification with computation times around 1 second.
