Over the last ten years, the scientific community has shown a strong interest for another
parameter which appears to be a sensitive indicator of the healthy or diseased character of a …

Portable wireless ultrasound has been emerging as a new ultrasound device due to its
unique advantages including small size, lightweight, wireless connectivity and affordability …

In this paper, a phase-based direct average strain estimation method is developed. A
mathematical model is presented to calculate axial strain directly from the phase of the zero …

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 …

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 …

Displacement estimation is a crucial step in ultrasonic strain imaging. The displacement
between a pre-and postcompression signal in the current data window is estimated by first …

In ultrasound strain and elasticity imaging, an accurate and cost-effective sub-pixel
displacement estimator is required because strain/elasticity imaging quality relies on the …

Estimation of tissue motion in the lateral direction remains a major challenge in 2-D
ultrasound strain imaging (USI). Although various methodologies have been proposed to …

Tracking the displacement between the pre-and post-deformed radio-frequency (RF) frames
is a pivotal step of ultrasound elastography, which depicts tissue mechanical properties to …

Ultrasonic strain imaging usually begins with displacement estimates computed using finite-
length sections of RF ultrasound signals. Amplitude variations in the ultrasound are known …
