Viscoelastic tissue estimation of shear rate in medical ultrasound imaging

摘要

For ultrasonic viscoelastic estimation, the shear wave velocity is measured for different locations in a region of interest (30). For each location, the shear rate is estimated without frequency band division. A distribution of shear wave velocities in the region of interest is matched (36) to a modeled distribution corresponding to a particular value of the viscoelastic property.
