Shear Wave Velocity Estimation Using the Real-Time Curve Tracing Method in Ultrasound Elastography

open access: yesApplied Sciences, 2021
The estimation of shear wave velocity is very important in ultrasonic shear wave elasticity imaging (SWEI). Since the stability and accuracy of ultrasonic testing equipment have been greatly improved, in order to further improve the accuracy of shear ...

Reverse Time Migration Imaging Using SH Shear Wave Data

open access: yesApplied Sciences, 2022
In this paper, we discussed the reverse time migration imaging of compressional wave (P-wave) and horizontally polarized shear wave (SH shear wave) seismic data, together with P- and SH shear wave constrained velocity model building. In the Sanhu area in

Simulation of Optical Coherence Elastography in Agar Based on Finite Element Analysis [PDF]

open access: yesE3S Web of Conferences, 2021
The finite element method is used to simulate the optical coherent elastic imaging in Agar. The shear wave velocity in Agar was measured by ARF-OCE system, and then the Agar model was established by finite element method, and then the shear wave velocity

Refraction of Surface Gravity Waves by Shear Waves [PDF]

open access: yesJournal of Physical Oceanography, 2006
Abstract Previous field observations indicate that the directional spread of swell-frequency (nominally 0.1 Hz) surface gravity waves increases during shoreward propagation across the surf zone. This directional broadening contrasts with the narrowing observed seaward of the surf zone and predicted by Snell’s law for bathymetric ...

P- 45 ENDOSCOPIC ULTRASOUND SHEAR-WAVE ELASTOGRAPHY OF THE RIGHT AND LEFT HEPATIC LOBE PREDICTS LIVER CIRRHOSIS: A DIAGNOSTIC TRIAL

open access: yesAnnals of Hepatology, 2023
Introduction and Objectives: The diagnostic work-up of chronic liver disease includes less invasive procedures such as transient elastography (TE), abdominal ultrasonography, esophagogastroduodenoscopy, and more invasive procedures, mainly portal ...

The Velocity of Shear Waves in Saturated Soil [PDF]

open access: yesSoil Science Society of America Journal, 2011
The velocities of shear waves in three different soils were measured as a function of consolidation using a Bishop and Wesley triaxial cell. We considered the soil deforming plastically on the normal consolidation line as well as elastic deformation on the rebound curve.

The scatter of time-delays in shear-wave splitting above small earthquakes [PDF]

open access: yes, 2004
Measurements of time-delays in seismic shear-wave splitting above small earthquakes typically display a scatter of often as much as ±80 per cent about the mean. Changes in the average time-delay appear to be related to changes of stress, but applications

Direct surface wave tomography for three dimensional structure based on surface wave traveltimes: Methodology review and applications

open access: yes地球与行星物理论评, 2023
Surface wave tomography using dispersion data to obtain isotropic and anisotropic shear wave velocity structures is a very efficient approach to study regional and global tectonics and deformation and to probe high-resolution crustal, upper mantle and ...
