  • Shear wave imaging
    Patent number: 8187187
    Abstract: Shear wave imaging is provided in medical diagnostic ultrasound. A region is imaged to determine a location in which to calculate shear velocity. The shear velocity is estimated for the location. The imaging may guide the identification of the location, reducing the time to determine useful shear information. The estimate of shear may be validated, such as using cross-validation, to indicate the confidence level of the shear value. The shear velocity may be displayed relative to a scale of shear velocities associated with a type of tissue, such as tissue for an organ. The location on a scale may be more intuitive for a user.
