Ultrasound (US) elasticity imaging is an extension of the ancient art of palpation and of
earlier US methods for viewing tissue stiffness such as echopalpation. Elasticity images …

In elasticity imaging, the ultrasound frames acquired during tissue deformation are analyzed
to estimate the internal displacements and strains. If the deformation rate is high, high-frame …

Elastography is based on the estimation of strain due to tissue compression or expansion.
Conventional elastography involves computing strain as the gradient of the displacement …

In this report, we present the regularization results of displacement vector measurement by
the multidimensional cross-spectrum phase gradient method (MC-SPGM), multidimensional …

The cross-correlation algorithm used to compute the local strain components for
elastographic imaging requires a minimum radio-frequency data segment length of around …

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 …

Bamber and Bush (1995) used the correlation coefficient for freehand elasticity imaging.
Varghese and Ophir (1996) found it to be a biased estimator of strain with a large variability …

This paper proposes a method of 2-D translations estimation using an a priori signal model.
Two analytical signals defined with multidimensional Hilbert transform are considered and …

Ultrasound's dynamic and interactive (ie, real-time) nature is it's major advantage compared
to other imaging modalities. For elasticity imaging, real-time data capture provides an …

Beyond all recent methods for estimating multidimensional motion vectors in ultrasound
(US) image sequences, the transverse oscillation (TO) images coupled with a phase-based …
