Abstract
A first ultrasound dataset that represents an object in a first coordinate system can be acquired at a first time. Three landmarks of the object can be located in the first ultrasound dataset to define a second coordinate system. A first transform from the first to the second coordinate system can be determined for the first ultrasound dataset. A second ultrasound dataset that represents the object in the first coordinate system can be acquired at a second time. The same three landmarks in the second ultrasound dataset can be located to define a third coordinate system. A second transform from the first to the third coordinate systems can be determined for the second ultrasound dataset.
