Abstract
In viscoelastic imaging with ultrasound, the shear wave speed or other viscoelastic parameter is measured by tracking at the ARFI focal or other high-intensity location relative to the ARFI transmission. Rather than tracking the shear wave, the tissue response to ARFI is measured. A profile of displacements over time or a spectrum thereof is measured at the location. By finding a scale of the profile resulting in sufficient correlation with a calibration profile, the shear wave speed or other viscoelastic parameter may be estimated.
