This paper proposes a novel approach to estimate the displacement fields, which is a
common and challenging step in ultrasound elastography. Maximization of normalized cross …

Motion tracking algorithms to derive the local displacement distribution inside soft tissue
from ultrasonic radio frequency (RF) signals are critical for ultrasound-based techniques …

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 …

In this paper, we have evaluated the use of smooth windows for ultrasound elastography. In
ultrasound elastography, local tissue strain is estimated using operations such as cross …

An efficient block matching and spectral shift estimation algorithm for freehand quasi-static
ultrasound elastography is described in this paper. The proposed method provides a …

Elastograms suffer from noise and undesirable artifacts, making it necessary to enhance
their signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) for accurate detection of …

Use of mathematical interpolation in Digital Signal Processing applications often seems to
be a remarkable solution when applied for noise reduction. In the last two decades …

In this work, a novel local spline smoothing-based approach is proposed in order to
despeckling medical ultrasound images. For better comparison, firstly nine conventional …

The composition, distribution and interaction of tissues found in tumours and their
surrounding stroma has to date revealed a wealth of information about cancer biology …
