Claim One:
1. A method for determining an amount of rotation of a structure, the method comprising: acquiring, by an ultrasound device, two-dimensional intersecting cross-plane images at a first acquisition period and at a second subsequent acquisition period; identifying, by a processor communicatively coupled to the ultrasound device, a first set of characteristic models forming a shape of the structure in the two-dimensional intersecting cross-plane images acquired at the first acquisition period; identifying, by the processor, a second set of characteristic models forming a shape of the structure in the two-dimensional intersecting cross-plane images acquired at the second subsequent acquisition period; determining, by the processor, the amount of rotation of the structure based at least in part on a difference in the shape of the first set of characteristic models and the shape of the second set of characteristic models; and presenting, at a display system, the determined amount of rotation of the structure.
