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 this paper, a 2-D locally regularized strain estimation method for imaging deformation of
soft biological tissues from radio-frequency (RF) ultrasound (US) data is introduced …

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

Tissue axial strain estimation with ultrasound elastography has become a hot field in recent
years. However, for keypoints tracking–based elastography algorithms, locating extrema in …

A strain-based elastography is developed to identify lesions from the phase information of
ultrasonic radio frequency (RF) signals in this study: a phase shift method using prior …

This paper introduces a 2-D strain imaging technique based on minimizing a cost function
using dynamic programming (DP). The cost function incorporates similarity of echo …

Displacement estimation is an essential step for ultrasound elastography and numerous
techniques have been proposed to improve its quality using two frames of ultrasound RF …

A novel zero-crossing tracking strain estimator (ZCT) has been developed for elastography.
This technique is based on tracking the zero-crossings between the pre-and …

Spectral estimation of tissue strain has been performed previously by using the centroid shift
of the power spectrum or by estimating the variation in the mean scatterer spacing in the …

This paper introduces two real-time elastography techniques based on analytic minimization
(AM) of regularized cost functions. The first method (1D AM) produces axial strain and …
