Ultrasound refers to any sound waves with frequencies greater than 20kHz. Diagnostic ultrasound typically uses frequencies between 2 and 20 million Hertz (Megahertz - MHz) The propagation speed of an acoustic wave traveling through a specific medium is determined by the stiffness of that medium. The greater the stiffness, the faster the wave ...

It was well demonstrated that using ultrasound could effectively enhance the leaching reaction rate by removing the passivating layer and increasing the mass transfer rates. This improvement would result from bubble cavitation and other mechanical-chemical mechanisms that ultrasounds can generate during ultrasound-assisted …

Among the two available USE techniques such as strain elastography (SE) and shear wave elastography (SWE) [116], SWE is the only one that is highly reproducible [32], [40], [50], [88]. In SWE, transversely aligned shear waves are produced by an acoustic radiation force during the application of an ultrasound probe to the tissue [77].
