Ultrasound strain imaging is used to measure local tissue deformations. Usually, only strains
along the ultrasound beam are estimated, because those estimates are most precise, due to …

In current ultrasound elastography, only the axial component of the displacement vector is
estimated and used to produce strain images. A method was recently proposed by our group …

Estimation of tissue motion in the lateral direction remains a major challenge in 2-D
ultrasound strain imaging (USI). Although various methodologies have been proposed to …

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 …

The goal of this study was to investigate the applicability of conventional 2-D displacement
and strain imaging techniques to phased array radiofrequency (RF) data. Furthermore, the …

In current practice, only one out of three components of the tissue displacement vector and
one of nine components of the strain tensor are accurately estimated and imaged in …

The current research and development of 2D (matrix-shaped) transducer arrays to acquire
3D ultrasound data sets provides new insights into medical ultrasound applications and in …

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 …

Ultrasonic strain imaging has drawn much attention recently because of its ability to
noninvasively provide information on spatial variation of the elastic properties of soft tissues …

Ultrasonic strain imaging usually begins with displacement estimates computed using finite-
length sections of RF ultrasound signals. Amplitude variations in the ultrasound are known …
