Displacement estimation is a key step in the evaluation of tissue elasticity by quasistatic
strain imaging. An efficient approach may incorporate a tracking strategy whereby each …

Two real-time strain imaging concepts and systems are presented. Both systems are based
on a conventional ultrasound scanner that is connected to a PC with an A/D converter card …

A theoretical formulation characterizing the noise performance of strain estimation using
envelope signals is presented for the cross-correlation based strain estimator in …

Ultrasound elastography is a prominent noninvasive medical imaging technique that
estimates tissue elastic properties to detect abnormalities in an organ. A common …

Elastography typically measures and images the normal strain component along the
insonification/compression axis, ie, in the axial direction. We have recently shown that, by …

In elastography, several methods for 2-D strain imaging have been introduced, based on
both raw frequency (RF) data and speckle-tracking. Although the precision and lesion …

Ultrasonography has been widely used for diagnosis since it was first introduced in clinical
practice in the 1970's. Since then, new ultrasound modalities have been developed, such as …

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 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 …

Ultrasonic strain imaging has drawn much attention recently because of its ability to
noninvasively provide information on spatial variation of the elastic properties of soft tissues …
