Conventional techniques in elastography estimate strain as the gradient of the displacement
estimates obtained through crosscorrelation of pre-and postcompression rf A-lines. In these …

In freehand elastography, quasi-static tissue compression is applied through the ultrasound
probe, and the corresponding axial strain is estimated by calculating the time shift between …

Quasi-static ultrasound elastography was introduced in the early 1990s to provide a way to
visualize the mechanical properties of target tissue. Most commonly, only the axial strain is …

Background: Freehand quasistatic strain imaging can reveal qualitative information about
tissue stiffness with good spatial accuracy. Clinical trials, however, repeatedly cite instability …

In biological tissue, an increase in elasticity is often a marker of abnormalities. Techniques
such as quasi-static ultrasound elastography have been developed to assess the strain …

Elastography involves tracking the ultrasonic A-mode signals before and after mechanical
compression of tissue to form a computed image of the local strains undergone by various …

Quasi-static ultrasound (US) elastography is now a well-established technique that involves
acquiring US (RF/envelope) signals from an imaging plane before and after a small quasi …

Energy-based displacement tracking of ultrasound images can be implemented by
optimizing a cost function consisting of a data term, a mechanical congruency term, and first …
