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 ).
