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 …

We reconstruct the elastic modulus distribution for one tissue mimicking (TM) phantom and
two in vivo biopsy-confirmed liver tumors using curvilinear ultrasound echo data. Spatial …

In ultrasound-based elastography methods, the estimation of shear wave velocity typically
involves the tracking of speckle motion due to an applied force. The errors in the estimates of …

We propose a beamforming scheme for ultrasound imaging leading to the generation of two
sets of images, one with oscillations only in the axial direction and one with oscillations only …

Ultrasound elastography (USE) is an emerging noninvasive imaging technique in which
pathological alterations can be visualized by revealing the mechanical properties of the …

In ultrasound strain and elasticity imaging, an accurate and cost-effective sub-pixel
displacement estimator is required because strain/elasticity imaging quality relies on 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 …

Ultrasound strain imaging is becoming increasingly popular as a way to measure stiffness
variation in soft tissue. Almost all techniques involve the estimation of a field of relative …

Using the incompressibility property of soft tissue, lateral displacements can be
reconstructed from axial strain measurements. Results of simulations and experiments on …

Obtaining accurate displacement estimates along both axial (parallel to the acoustic beam)
and lateral (perpendicular to the beam) directions is an important task for several clinical …
