摘要： 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.

摘要： 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).
