This paper proposes a novel approach to estimate the displacement fields, which is a
common and challenging step in ultrasound elastography. Maximization of normalized cross …

Objective: Displacement estimation (also known as time-delay estimation (TDE)) is a
challenging step in ultrasound elastography. The main issue of existing TDE techniques is …

Ultrasound elastography has been widely applied in clinical diagnosis. To produce high-
quality elastograms, displacement estimation is important to generate ne displacement map …

Quasi-static ultrasound elastography (USE) is an imaging modality that consists of
determining a measure of deformation (ie strain) of soft tissue in response to an applied …

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 …

In ultrasound elastography, the strains in the axial direction are usually calculated by
applying gradient operator on the estimated axial displacements. Unfortunately, the direct …

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 …

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 …

In this paper, we present a new approach to calculate 2D strain through the registration of
the pre-and post-compression (deformation) B-mode image sequences based on an …

A major challenge of free-hand palpation ultrasound elastography (USE) is estimating the
displacement of RF samples between pre-and post-compressed RF data. The problem of …
