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