  • In-vivo quantification of fat content in an organ of a living subject using ultrasound
    Patent number: 12376819
    Abstract: A method is disclosed for determining the percent volume of fat in an organ (advantageously, the liver) of a living subject. Radiation (advantageously shear waves of known frequency and amplitude) is directed into the liver. The speed with which the radiation propagates within the liver, and the attenuation of the amplitude of the radiation caused by the liver, are measured. From these measured quantities, the percent volume of fat in the liver can be determined. The determination can be carried out by calculation, or by using a nomogram.
    Type: Grant

    Assignee: UNIVERSITY OF ROCHESTER

  • Reverberant shear wave gradients for ultrasound elastography
    Patent number: 12285293
    Abstract: The wave number and phase velocity (shear wave speed) of ultrasound energy within an organ of interest are calculated using a herein-disclosed phase gradient calculation method. This calculation method is less sensitive to imperfections in the reverberant field distribution and requires a smaller support window, relative to earlier calculation methods based on autocorrelation. Applications are shown in simulations, phantoms, and in vivo liver.
