Abstract Changes in tissue elasticity are correlated with certain pathological changes, such
as localized stiffening of malignant tumours or diffuse stiffening of liver fibrosis or placenta …

Medical imaging is vital to modern clinical practice, enabling clinicians to examine tissues
inside the human body non-invasively. Its value depends on accuracy, resolution, and the …

This paper presents the first near-real-time freehand ultrasound elastography system using
a (3-D) mechanical probe. Acquisition is complete within two sec, and only an additional 20 …

Most quasi-static ultrasound elastography methods image only the axial strain, derived from
displacements measured in the direction of ultrasound propagation. In other directions, the …

In biological tissue, an increase in elasticity is often a marker of abnormalities. Techniques
such as quasi-static ultrasound elastography have been developed to assess the strain …

This thesis describes a system to measure the mechanical properties of soft tissue. The
mechanical properties depend on the type of tissue (eg fat, muscle, blood) and the presence …

Ultrasound elasticity imaging has been a research interest for the past 20 years with the goal
of generating novel images of soft tissues based on their material properties (ie, stiffness …

Neoplastic tissue is typically highly vascularized, contains abnormal concentrations of
extracellular proteins (eg collagen, proteoglycans) and has a high interstitial fluid pressure …

In this dissertation, we investigate the feasibility of using high frequency ultrasound, to
measure tissue motion and tissue elasticity for medical imaging applications. Ultrasound …

High-frame rate ultrasound imaging is necessary to track fast deformation in ultrasound
elasticity imaging, but the image quality may be degraded. Previously, we investigated the …
