A system and method are provided for determining at least one torsion angle of a left ventricle. The method includes the steps of collecting three-dimensional ultrasound data of the left ventricle (36) to obtain at least one first two-dimensional view and at least one second two-dimensional view thereof, wherein the first two-dimensional view is obtained at about the beginning of a cardiac phase and the second two-dimensional view is obtained at about the end of the cardiac phase, placing at least two tracking points (40, 42) on the at least one first two-dimensional view to draw a first torsion line (44), tracking the at least two tracking points to extrapolate the position thereof on the at least one second two-dimensional view and to draw a second torsion line (46), and calculating the at least one torsion angle by measuring an angle (A) formed by the intersection of the first and second torsion lines (44, 46). |
