It is known that changes in the mechanical properties of tissues are associated with the
onset and progression of certain diseases. Ultrasound elastography is a technique to …

Ultrasound elastography (USE) or elastosonography is an ultrasound-based, non-invasive
imaging method for assessing tissue elasticity. The different types of elastosonography are …

Background The convectional strain-based algorithm has been widely utilized in clinical
practice. It can only provide the information of relative information of tissue stiffness …

The current research and development of 2D (matrix-shaped) transducer arrays to acquire
3D ultrasound data sets provides new insights into medical ultrasound applications and in …

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

Despite many uses of ultrasound, some pathologies such as breast cancer still cannot
reliably be diagnosed in either conventional B-mode ultrasound imaging nor with more …

In elastography, conventional linear array (CLA)-based RF data acquisition provides more
accurate displacement measurements in the direction of beam propagation (axial direction) …

Elasticity imaging is based on the measurements of local tissue deformation. The approach
to ultrasound elasticity imaging presented in this paper relies on the estimation of dense …

In conventional elastography, strain is estimated from the gradient of the displacement (time-
delay) estimates. The displacement estimates involve estimating the peak location of the …

Ultrasound elastography is becoming a widely available clinical imaging tool. In recent
years, several realtime elastography algorithms have been proposed; however, most of …
