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 ultrasound elastography, the strain in compressed tissue due to external deformation is
estimated and is smaller in harder than softer tissue. With increased stress, the nonaxial …

Ultrasound strain imaging maps the tissue stiffness in the region of interest by estimating
strain when the tissue is stressed. Prestress and poststress ultrasound echoes are …

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

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

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 …

In freehand elastography, quasi-static tissue compression is applied through the ultrasound
probe, and the corresponding axial strain is estimated by calculating the time shift between …

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

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

Robust strain estimation is important in elastography. However, a high signal-to-noise ratio
(SNR) and contrast-to-noise ratio (CNR) are sometimes attained by sacrificing resolution …
