achieve this goal, three radiofrequency echo frames are selected by an automated …

Tracking the displacement between the pre-and post-deformed radio-frequency (RF) frames
is a pivotal step of ultrasound elastography, which depicts tissue mechanical properties to …

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 …

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 …

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 …
