Quasi-static ultrasound elastography (USE) is an imaging modality that consists of
determining a measure of deformation (ie strain) of soft tissue in response to an applied …

In this paper, a novel real-time kernel-based and gradient-based Phase Root Seeking (PRS)
algorithm for ultrasound elastography is proposed. The signal-to-noise ratio of the strain …

Deformation of tissue can be accurately estimated from radio-frequency ultrasound data
using a 2-dimensional normalized cross correlation (NCC)-based algorithm. This procedure …

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

The accuracy and precision of the strain estimates in elastography depend on a myriad
number of factors. A clear understanding of the various factors (noise sources) that plague …

A new estimator, which estimates directly strain as scaling factor or time delay is presented.
The algorithm is based on the zero seeking of cross-correlation imaginary part. This term …

Since the waveform of an echo is more distorted under larger compression, elastography
can be applied in cases where the compression is only a few percent. To reduce errors due …

Ultrasound transducers are commonly tracked in modern ultrasound navigation/guidance
systems. In this article, we demonstrate the advantages of incorporating tracking information …

Cross‐correlation functions are derived with the purpose of determining how strain
inhomogeneities affect the displacement estimates used in ultrasound‐based elastography …

Various techniques for tissue elasticity imaging have been proposed in the last decade. For
clinical applications, real-time and freehand manipulation of a probe is required. In a …
