In conventional elastography, strains are estimated by computing gradient of estimated
displacement. However, gradient-based algorithms are susceptible to noise. We have …

Elastography is based on the estimation of strain due to applied tissue compression. In
conventional elastography, strain is computed from 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 …

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 …

Elastography is a method for imaging the elastic properties of compliant tissues which
produces gray scale elasticity images called elastograms. The elastograms of phantoms …

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

We describe a new method for quantitative imaging of strain and elastic modulus
distributions in soft tissues. The method is based on external tissue compression, with …

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 can produce quality strain images in vitro and in vivo. Standard elastography
uses a coherent cross-correlation technique to estimate tissue displacement and tissue …

Elastography is a technique for the estimation of tissue elasticity that is based on the
estimation of strain. Tissue strain can be estimated by finite difference computations of echo …
