This manuscript reports a technical innovation that has been developed for real-time,
freehand strain imaging. This work is based on a well-known block-matching algorithm with …

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 …

Displacement estimation is a crucial step in ultrasonic strain imaging. The displacement
between a pre-and postcompression signal in the current data window is estimated by first …

This paper investigates a new approach devoted to displacement vector estimation in
ultrasound imaging. The main idea is to adapt the image formation to a given displacement …

Ultrasound elastography involves measuring the mechanical properties of tissue, and has
many applications in diagnostics and intervention. A common step in different elastography …

Ultrasound elasticity imaging shows promise as a new way for early detection of cancers by
assessing the elastic characteristics of soft tissue. So far the commonly used approach …

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 …

A new method is proposed to estimate the motion and relative local compression between
two successive ultrasound RF signals under different compression states. The algorithm …

Ultrasound Shearwave Elasticity Imaging (SWEI) is a set of methods for measuring the
elastic properties of biological tissues. Since the elastic properties of tissue are known to …

Deformation of tissue can be accurately estimated from radio-frequency ultrasound data
using a 2-dimensional normalized cross correlation (NCC)-based algorithm. This procedure …
