The principle behind shear wave elastography
Shear waves are generated inside the human body by means of an ultrasonic burst (left). Depending on tissue stiffness, shear waves travel at varying speed, but generally very slowly through the human body. Their propagation can be followed and visualized using conventional ultrasound imaging techniques (right). The propagation speed of the shear waves directly correlates with tissue stiffness.
