We reconstruct the elastic modulus distribution for one tissue mimicking (TM) phantom and
two in vivo biopsy-confirmed liver tumors using curvilinear ultrasound echo data. Spatial …

This paper investigates a new approach devoted to displacement vector estimation in
ultrasound imaging. The main idea is to adapt the image formation to a given displacement …

In current practice, only one out of three components of the tissue displacement vector and
one of nine components of the strain tensor are accurately estimated and imaged in …

In this paper, a novel computationally efficient quasi-static ultrasound elastography
technique is introduced by optimizing an energy function. Unlike conventional elastography …

Abstract Changes in tissue elasticity are generally correlated with pathological phenomena.
For example, diffuse liver disease progressively reduces the elasticity of the liver. Quasi …

Displacement estimation is an essential step for ultrasound elastography and numerous
techniques have been proposed to improve its quality using two frames of ultrasound RF …

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 …

Similar to many other types of cancer, liver cancer is associated with biological changes that
lead to tissue stiffening. An effective imaging technique that can be used for liver cancer …

It is known that the elasticity of liver reduces progressively in the case of diffuse liver
disease. Currently, the diagnosis of diffuse liver disease requires a biopsy, which is an …

The limits and trade-offs of the axial resolution in elastography were investigated using a
controlled simulation study. The axial resolution in elastography was estimated as the …
