Medical Ultrasonic Elasticity Imaging Techniques [PDF]

open access: bronzeJournal of the Korean Society for Nondestructive Testing, 2012
Breast and prostate tumors or cancers tend to be stiffer than the surrounding normal tissue. However, the difference in echogenicity between cancerous and normal tissues is not clearly distinguishable in ultrasound B-mode imaging. Thus, imaging the stiffness contrast between the two different tissue types helps to diagnose lesions quantitatively, and ...

Magnetic‐resonance imaging techniques for detection of elasticity variation [PDF]

open access: greenMedical Physics, 1995
The relative success of manual palpation in the detection of breast cancer would suggest that a method for remote palpation resulting in a measurement of tissue elasticity could provide a diagnostic tool for detecting cancerous lesions deeper within the breast.

Improving Displacement Signal-to-Noise Ratio for Low-Signal Radiation Force Elasticity Imaging Using Bayesian Techniques [PDF]

open access: greenUltrasound in Medicine & Biology, 2016
Radiation force-based elasticity imaging is currently being investigated as a possible diagnostic modality for a number of clinical tasks, including liver fibrosis staging and the characterization of cardiovascular tissue. In this study, we evaluate the relationship between peak displacement magnitude and image quality and propose using a Bayesian ...

Spectral strain estimation techniques for tissue elasticity imaging

open access: gold, 2005
This research project examines the applicability of novel spectral domain strain estimation algorithms to improve the clinical value of tissue elasticity images. Pathological changes can be frequently correlated to changes in soft tissue stiffness. Despite the fact that many cancers, including those found in the breast and prostate, often manifest ...

A constant compliance force modulation technique for scanning force microscopy (SFM) imaging of polymer surface elasticity [PDF]

open access: closedUltramicroscopy, 1996
A new method of force modulation scanning force microscopy (SFM) imaging based on a constant compliance feedback loop is presented. The feedback adjusts the loading force applied by the SFM tip to the surface in order to maintain a constant compliance beneath the tip.

Endoscopic ultrasound elastography-- a new imaging technique for the visualization of tissue elasticity distribution.

open access: closedJournal of gastrointestinal and liver diseases : JGLD, 2006
Endoscopic ultrasound (EUS) elastography is an imaging procedure used for the visualization of tissue elasticity during usual EUS examinations. EUS elastography can be accomplished real-time with state-of-the-art ultrasound systems, with the images being represented in transparent color superimposed on the conventional gray-scale B-mode scans.

A Comparison of Shear Wave Elastography between Normal Myometrium, Uterine Fibroids, and Adenomyosis: A Cross-Sectional Study [PDF]

open access: yesInternational Journal of Fertility and Sterility, 2022
Background: The differential diagnosis between uterine fibroid and adenomyosis is sometimes difficult; a precise diagnosis is required in women with infertility because of the different choice of treatments.
