Failures for evaluation among surfaces from geometrically constrained image segmentation method and manual delineation at end diastole and end systole. DSI (dice similarity index) indicates that the quantity of agreement among the traced and source volumes. (surface distance mean) displays the standard distance, among the traced and source surfaces.

	DSI (mean ± std)	(mean ± std)
End diastole	0.91 ± 0.07	2.26 ± 0.78
End systole	0.79 ± 0.05	1.64 ± 0.45
