"The concept is similar to strain elastography, but instead of using transducer pressure to compare a shift in an ultrasound A-line (thereby measuring changes in strain), a higher intensity pulse is transmitted to produce shear waves, which extend laterally from the insonated structure. The shear waves may then be tracked with low-intensity pulses to find the shear velocity, which is related to Young's modulus."
