摘要： 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.

摘要： The invention relates to an imagining method which is used to observe the simultaneous propagation of a shear wave at a multitude of points in a viscoelastic diffusing medium (1). The inventive method consists in: generating the shear wave by using a network of transconductors (6) to emit at least one focused ultrasonic compression wave in the viscoelastic medium; subsequently, using the same network of transconductors to emit non-focused ultrasonic compression waves at a rapid rate, in order to produce a series of images of the medium; and processing the images thus obtained in delayed time in order to determine movements in relation to the medium during the propagation of the shear wave.

摘要： An imaging method using shear waves for observing a viscoelastic medium (2), comprising: several successive excitation steps j during which elastic shear waves are generated respectively at different excitation loci (L
j ) in the viscoelastic medium (2) 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 Im
j (t
k ) of the viscoelastic medium at times t
k 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 Im
j (t
k ) corresponding to the same relative time t
k are averaged to determine an average image Im' (t
k ).
