The transmission of the sound wave is completely painless.
WebApr 12, 2024 · Shear-wave elastography (SWE) is an emerging method that enables muscle-specific assessment of passive stiffness in vivo through shear modulus quantification. Briefly, SWE is based on exciting a shear-wave using an acoustic push, and subsequently measuring the speed with which the shear-waves propagate across the tissue (for … WebJan 8, 2024 · Elastosonography is based on the emission of short-lived (0.03–0.4 ms) high-energy acoustic pulses generated by the probe, which induce a small amount of local displacement (1–20 μm) in the tissue. The so-called “shear waves” are generated following that displacement, which can be detected by the probe.
