Ultrasound elastography has been developed as a modality that provides novel diagnostic
information on tissue stiffness and replaces conventional palpation used for breast …

Accurately estimating all strain components in quasi-static ultrasound elastography is crucial
for the full analysis of biological media. In this study, 2D strain tensor imaging was …

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 this paper, a new parameter that quantifies the intensity of tissue nonlinear elasticity is
introduced as the nonlinear elasticity parameter. This parameter is defined based on the …

Numerous experimental and computational methods have been developed to estimate
tissue elasticity. The existing testing techniques are generally classified into in vitro, invasive …

Quasi-static ultrasound elastography (QSUE) is an imaging technique that mainly provides
axial strain maps of tissues when the latter are subjected to compression. In this article, a …

Imaging of tissue elasticity is promising as a technique for visualizing tissue variations such
as tumors from the point of view of hardness. Evaluation of the elasticity has hitherto been …

Cette thèse concerne l'estimation du mouvement dans des séquences d'images
échographiques, avec comme application médicale l'élastographie statique de la thyroïde …

This study focuses on the reconstruction of the shear modulus contrast in linear elastic and
isotropic media, in quasi-static ultrasound elastography. The method proposed is based on …

Reconstructing tissue elastic properties from dis-placements measured in quasi-static
ultrasound elastography is a challenging task. Indeed, it requires to solve an ill-posed …
