Conventional techniques in elastography estimate the axial strain as the gradient of the
displacement (time-delay) estimates obtained using cross-correlation of pre-and temporally …

In elastography, change in signal shape from tissue deformation and nonaxial tissue motion
reduce correlation between the pre-and postcompression echo signals. Appropriate global …

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 …

Elastography involves tracking the ultrasonic A-mode signals before and after mechanical
compression of tissue to form a computed image of the local strains undergone by various …

In conventional elastography, strain is estimated from the gradient of the displacement (time-
delay) estimates. The displacement estimates involve estimating the peak location of the …

An experimental study of the spatial resolution in elastography was conducted. Models that
involved two cylindrical inclusions arranged as a wedge were used to characterize the axial …

Conventional techniques in elastography estimate strain as the gradient of the displacement
estimates obtained through crosscorrelation of pre-and postcompression rf A-lines. In these …

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 conventional elastography, internal tissue deformations, induced by external compression
applied to the tissue surface, are estimated by cross-correlation analysis of echo signals …

A least-squares strain estimator (LSQSE) for elastography is proposed. It is shown that with
such an estimator, the signal-to-noise ratio in an elastogram (SNRe) is significantly …
