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： 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 ).-

摘要： Method of high-resolution ultrasound imaging, in which transducers (T
1 -T
n ) are made to emit ultrasound waves in a field of observations containing micro bubbles, by making the micro bubbles burst one by one in tandem with the emissions of ultrasound waves. At each shot j of an ultrasound wave, raw reverberated signals S
j (i,t) picked up by each transducer i are recorded, and then differential signals V
j (i,t) representative of variations between successive raw signals are determined, a parabolic function P
j (x) is fitted to the differential signals corresponding to each shot j, and then a crest A
j (x
0 ,y
0 ) of this function P
j , corresponding to the position of the micro bubble destroyed between shots j-1 and j, is determined.-

摘要： 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. 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.
