摘要： An imaging method using shear waves for observing a viscoelastic medium, comprising: several successive excitation steps j during which elastic shear waves are generated respectively at different excitation loci (Lj) in the viscoelastic medium by an imaging device, the different excitation loci being separated from one another by a maximum distance Dm, an imaging step corresponding to each excitation step j, in which a set j of successive raw images Imj(tk) of the viscoelastic medium at times tk are determined during propagation of the shear wave, the raw images having a resolution R which is larger than the maximum distance Dm, an averaging step in which raw images Imj(tk) corresponding to the same relative time tk are averaged to determine an average image Im′(tk).

摘要： Method for rheological characterization of a viscoelastic medium, with the following steps: (a) an excitation step during which a vibratory excitation is generated in the viscoelastic medium leading to a deformation of the medium, (b) a deformation measurement step during which the deformation of the medium caused by the excitation is observed, (c) and a characterization step during which at least one non-zero power parameter y is determined such that a rheological parameter of the medium x is equal to x(f)=a+b·fy, where f is the frequency, a is a real number and b a non-zero scale parameter. It is thus possible to obtain mapping of the power parameter y.

摘要： The invention concerns a device (1) for the insonification of an environment or medium, which is designed to generate a beam of focussed waves around a point in a so-called focus zone (20), used for imaging the medium or changing the properties of the medium, with the insonification device (1) having an intrinsic or extrinsic support structure on which is installed a network of a predetermined number of ultrasound transducers (12) that are designed to be controlled independently for generation of the focussed wave beam. According to the invention, the transducers (12) used for the generation of the focussed wave beam are located in a homogeneous spatial distribution along at least two concentric spirals (11) that are wound onto a three-dimensional concave area (10) whose shape and size are chosen to allow optimal focusing of the beam at a predetermined focal length, and whose concave side is oriented toward the focus zone (20).

摘要： The invention concerns a method for optimizing the focusing of waves in a zone of interest of a medium, with the waves being emitted by a network of sources to the medium through an aberration-inducing element that introduces an initially indeterminate phase shift. The method according to the invention proposes to use M−1 successive modifications of the emitted wave, each giving rise to a perturbation. According to the invention, the M perturbations are measured in the zone of interest at each modification of the phase and/or amplitude distributions, and these measurements are used to deduce optimal focusing characteristics to maximize the perturbation induced in the zone of interest.

摘要： A shear wave elastography method for imaging an observation field in an anisotropic medium, including an initial ultrasonic acquisition step during which initial physical parameters are acquired in at least one region of interest; a spatial characterization step during which a set of spatial characteristics of the anisotropic medium is determined on the basis of the initial physical parameter; an excitation substep during which an shear wave is generated inside the anisotropic medium on the basis of the set of spatial characteristics; and an observation substep during which the propagation of the shear wave is observed simultaneously at a multitude of points in the observation field.
