Elastography aims at assessing tissue elasticity. As a branch of ultrasound elastography (UE), shear-wave elastography is recognized by engineering and clinical fields, particularly fast shear-wave elastography (SWE). Shear-wave elastography (SWE) is a real-time, two-dimensional elastography technology that has emerged in recent years. It is different from Static Elastography, and also different from Transient Elastography and Acoustic Radiation Force Impulse. Based on the fact that the elastic moduli of different tissues are several orders of magnitude greater than the acoustic impedance differences, Elasticity imaging instruments for clinical use have been developed, and has gradually matured. A new stage of technological progress has occurred with SWE. This paper introduces the principle behind the use of elastography and several elastography technologies in clinical application, and then explores methods for fulfilling the promises of this technology: real time and superfast. Furthermore, methods for the generation and detection of Shear Waves are enumerated. These include, for example, the dynamic coherence enhancement technique based on “Mach Waves” and ultra-high-frequency imaging technology for simultaneous transmitting and receiving. Finally, the future development of Shear-wave elastography is discussed. It is believed that with the development of new technologies and new materials, shear wave elastography (SWE) will play an increasingly important role in clinical practice.
