Philips shear wave elastography simplifies liver assessment, making obtaining liver stiffness measurements fast and easy. This non-invasive, reproducible, and easily performed method of assessing liver tissue stiffness may help reduce, or even avoid, the need for conventional liver biopsies 1 .

Liver shear wave elastography provides stiffness measurements for assessment of diffuse liver diseases and neoplastic lesions of the liver. It is noninvasive, so for some patients, shear wave elastography can turn painful, expensive biopsies into a well-tolerated method for follow up and monitoring of the disease. The velocity of the shear wave generated through the tissues may be calculated using standard B-mode ultrasound sampling techniques ( Fig. 4.1). From the velocity of the shear wave through the tissues the strain (Young) modulus can be estimated. The velocity of the shear wave is proportional to the tissue stiffness. Shear-wave data processing, signal recovery, and interpretation are unnec-essarily complicated (and often ques-tionable) in field coordinates because of this spatially variable mixing of wave modes.

Shear wave travel times, amplitudes and broadband waveforms from 16 events in the Kurile slab are analyzed to place further constraints on the seismic velocity heterogeneity associated with the subducted oceanic lithosphere. Several previous studies have proposed that the Kurile slab penetrates into the lower Real-time shear wave demonstrates lateral deformation of tissues and direct assessment of a propagating wave.

A high‐resolution shear wave velocity model can provide improved understanding of the Tibetan structure and crustal deformation with complicated tectonic evolution. Based on continuous seismic observations at approximately 400 stations, we collected over 10,000 Rayleigh wave phase velocity dispersion curves extracted from ambient noise cross‐correlation functions.
