Patents by Inventor Stephen Rosenzweig

Stephen Rosenzweig has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Sound speed imaging using shear waves
    Patent number: 11006928
    Abstract: Shear wave propagation is used to estimate the speed of sound in a patient. An ultrasound scanner detects a time of occurrence of a shear wave at each of multiple locations. The difference in time of occurrence, given tissue stiffness or shear velocity, is used to estimate the speed of sound for the specific tissue of the patient.
    Type: Grant
    Filed: February 10, 2016
    Date of Patent: May 18, 2021
    Assignee: Siemens Medical Solutions USA, Inc.
    Inventors: Yassin Labyed, David Duncan, Seungsoo Kim, Stephen Rosenzweig, Liexiang Fan
  • Frequency compounding in elasticity imaging
    Patent number: 10675007
    Abstract: For noise reduction in elasticity imaging, frequency compounding is used. Displacements caused by the acoustic radiation force impulse are measured using signals at different frequencies, either due to transmission of tracking pulses and reception at different frequencies or due to processing received signals at different sub-bands. The displacements are (a) combined to compound and the compounded displacements are used to determine elasticity or (b) are used to determine elasticity and the elasticities from information at the different frequencies are compounded.
