Ultrasound elastography is emerging with enormous potential as a medical imaging
modality for effective discrimination of pathological changes in soft tissue. It maps the tissue …

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

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 …

A major disadvantage of the current practice of elastography is that only the axial component
of the strain is estimated. The lateral and elevational components are basically disregarded …

Most strain imaging techniques follow a pipeline strategy: in the first step, tissue
displacement is estimated from radio-frequency (RF) frames, and in the second step, a …

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 …

Palpation has been widely used to detect hard tumorous tissues surrounded by softer
normal tissues. The goal of ultrasound tissue elasticity imaging is to extract information …

Ultrasound elastography is the method of obtaining relative stiffness information of biological
tissue, which plays an important role in early diagnosis. Generally, a gradient-based strain …

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 …

Tissue axial strain estimation with ultrasound elastography has become a hot field in recent
years. However, for keypoints tracking–based elastography algorithms, locating extrema in …
