Measurement of tissue mechanical properties with shear wave dispersion ultrasound vibrometry (SDUV).
Shear wave dispersion vibrometry (SDUV) produces motion in tissue using sequential pulses of ultrasound radiation pressure. The resulting motion of the tissue in the form of propagating shear waves can provide information about the material properties of the tissue given the appropriate equations of motion for the geometry of the tissue. An example application of the method is described to measure material properties in bovine tissue.
