We propose a new method for strain field estimation in quasi-static ultrasound elastography
based on matching RF data frames of compressed tissues. The method benefits from using …

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 …

In freehand elastography, the ultrasound probe is moved to compress the tissue while RF-
data are acquired. The axial strain tensor is estimated by calculating the gradient of the axial …

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 …

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 …

In the conventional cross-correlation-based strain estimation, there is a trade-off between
the interpolation accuracy and the computational requirement. On the other hand, the …

Ultrasound transducers are commonly tracked in modern ultrasound navigation/guidance
systems. In this article, we demonstrate the advantages of incorporating tracking information …

This paper introduces a novel technique to estimate tissue displacement in quasi-static
elastography. A major challenge in elastography is estimation of displacement (also referred …

Ultrasound strain imaging maps the tissue stiffness in the region of interest by estimating
strain when the tissue is stressed. Prestress and poststress ultrasound echoes are …

Ultrasound elastography performed under small strain conditions has been intensively
studied. However, small deformations may be not sufficiently large to differentiate some …
