Abstract
In accordance with embodiments disclosed herein, systems, methods, and computer programs are provided that determine a mechanical property of a subject. An excitation force is applied to a displacement origin within a subject, and a shear wave is generated in response to application of the excitation force. The displacement data indicative of displacement motion at the sample position is sampled by tracking pulses, and the timing of at least one of the tracking pulses is adjusted relative to application of the excitation force. The process continues until a peak displacement of the shear wave for the sample position is determined based upon the displacement data.
