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 () 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 () on the at least one first two-dimensional view to draw a first torsion line (), 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 (), and calculating the at least one torsion angle by measuring an angle (A) formed by the intersection of the first and second torsion lines ().

System and method for measuring left ventricular torsion

An ultrasound system that has transmit and receive circuitry that, pursuant to a plurality of image settings, transmits ultrasound signals into a patient, receives echoes from a patient and outputs a signal representative of the echo. Control circuitry is provided that sequentially adjusts the image settings so as to cause the transmit and receive circuitry to have a sequence of imaging configurations during an ultrasound imaging study. A memory may be provided that stores a plurality of state diagrams, each defining a sequence of imaging configurations for a particular imaging study, which are accessible by the control circuitry, wherein the control circuitry accesses a selected state diagram to conduct an imaging study. Such a system is particularly useful for imaging studies that utilize contrast agents.
