An ultrasound imaging method for generating a visualization image includes an emission and reception step of interleaved ultrasound waves, a processing step during which the received sequences are processed for generating three images via three different process, an image combining step during which the visualization image is determined by combining the three images for simultaneously visualizing the results of all images process.

Ultrasound imaging method and an apparatus implementing said method

Method for ultrasound determination of a corrected image of a medium, the method comprising: determination of a temporal succession of images (Ik) of the medium, determination of the movement for each image of the medium, determination of a temporal succession of partial strain images (IΔε) based on images of the medium, determination of corrected partial strain images (IΔε*) by compensation of said partial strain images (IΔε) based on preceding movements, and determination of a corrected strain image (Iε*) by summation of the preceding corrected partial strain images (IΔε*).

Method for ultrasound determination of a corrected image of a medium, and device for implementing this method

An ultrasound system comprising a probe adapted for emitting and receiving ultrasound waves inside a medium, and a processing unit connected to said probe and adapted for processing signals from the probe. The probe is configured so as to behave as a Fresnel lens for focusing the ultrasound waves. The processing unit analyses signals from the probe for sensing the medium at a plurality of focal points.

Ultrasound system

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.

Method and apparatus for measuring a physical parameter in mammal soft tissues by propagating shear waves

A Method for measuring heart contractility of a patient, in which a mechanical shear wave is propagated through the heart and observation of the propagation leads to determine a shear wave propagation parameter representative of the elasticity of the heart is disclosed. The value of the propagation parameter at the end of a systole is sampled, which leads to a parameter representative of the end systolic elastance.
