Method for measuring a physical parameter in soft tissues of a mammal, in which a mechanical shear wave is propagated through the soft tissues and observation of the propagation leads to determine values of a shear wave propagation parameter. The physical parameter is computed on the basis of these values.

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).


The invention relates to a method for measuring a mean visco-elasticity value for a soft material. Said method using a single probe carrying at least one transducer comprises the steps of: a) inducing, in a constraint zone, at least one burst of mechanical vibrations in order to generate internal shear waves in the tissue propagating from said constraint zone into the tissue, b1) measuring, with said transducer, the transient tissue displacements in at least one first measurement zone in the tissue, said first measurement zone being located away from said constraint zone, c) estimating a mean visco-elasticity of the region of the tissue situated between the constraint zone and the first measurement zone from said measured transient tissue displacements of the tissue in the first measurement zone.

The invention concerns an electronic display system, intended to be coupled with ultrasound imaging equipment capable of capturing an image of a medium, said system comprising a first monitor to display an ultrasound image such as captured by the ultrasound imaging equipment and image processing means. According to the invention, the system further comprises a second touch-screen monitor, means to duplicate the ultrasound image, means to send this duplicate to the second monitor on which at least part therefore is displayed, means to display at least one graphical element which, by means of the tactility of the screen, is used to perform at least one processing operation on the ultrasound image, means for instant application of all processing operations performed using the second monitor to the duplicate ultrasound image displayed on the second monitor, and means for instant or deferred application to the ultrasound image displayed on the first monitor of all or part of the processing operations performed on the duplicate ultrasound image by means of the second monitor.


The ultrasound imaging system comprises an ultrasound probe (3) and computer (20) for controlling the ultrasound probe and for visualizing an image. The system comprises a processing device located between the probe and the computer that comprises a processing unit (15) to operate an imaging method and switch unit (13) for routing the input and output data.


A method for determining a physical characteristic on a punctual location inside a medium, comprising the steps of: sending an emitted sequence comprising emitted pulses having different amplitudes, receiving a received sequence comprising received pulses corresponding to echoes of said emitted pulses, calculating a phase difference between the received pulses relative to the emitted pulses, and determining the physical characteristic on the bases of said phase difference.

The disclosure includes a method of acquiring high-resolution ultrasound images using an array of transducers using successive transmission matrices. Implementations include operations for determining inter-transducer correlation matrices of an area of interest and an unwanted area; determining a characteristic matrix of the area of interest from the product of the inverse of the inter-transducer correlation matrix of the unwanted area and the inter-transducer correlation matrix of the area of interest; calculating eigenvectors and values of the characteristic matrix to define a transmission matrix; adjusting the image acquisition rate and image quality in order to define eigenvectors for firing; multiplying a reception matrix comprising the acquired signals completed by data set to zero corresponding to the firings not effected by the inverse of the transmission matrix to obtain a complete data set; reconstructing a high-resolution image of the area of interest as in synthetic aperture echographic imaging methods.
