Abstract: A method of evaluating ultrasound data for the purpose of ultrasound attenuation estimation in a medium, the medium being associated with ultrasound spatio-temporal signal data received from the medium in response to at least one ultrasound plane and/or diverging wave emitted into the medium, the method including beamforming a first subset of ultrasound spatio-temporal signal data to obtain a second subset of beamformed ultrasound data, determining a focusing quality criterion from the first subset, and evaluating the second subset as a function of the focusing quality criterion of the first subset.

Abstract: An ultrasonic method for quantifying the nonlinear shear wave elasticity of a medium, the method comprising the following steps: A1.—collecting a temporal succession of shear wave elasticity data from the medium, A2.—applying, to the medium, a deformation that successively changes according to a predetermined sequence of deformations, during the collection of the shear waves, A3.—observing the actual evolution of deformation, and B.—quantifying the nonlinear elasticity of the medium depending on the temporal succession of data and the evolution of deformation.

Abstract: Examples of the disclosure relate to a method and a device for determining the condition of the liver of a subject. The method includes obtaining a first group of scan data from ultrasonic waves propagating according to a first scan configuration of the liver, obtaining a second group of scan data from ultrasonic waves propagating according to a second scan configuration of a group of tissues of the subject, and determining, by a combination of the first and second groups of scan data, an indicator representative of the condition of the liver.

Abstract: A method for compensating a depth-dependent attenuation in ultrasonic signal data of a medium and a system for performing the method. The method is implemented by a processing system (8), the method comprising the following: processing (c), in which ultrasound signal data is processed by the processing unit for providing in-phase and quadrature phase (IQ) data of the medium, and attenuation compensation (f), in which a phase of the IQ data is compensated as a function of a respective frequency shift amount for each of a plurality of different depths (z1, z2, zn) in the medium, such that the IQ data spectrum is recentered across the plurality of different depths.
