摘要：The invention relates to an imagining method which is used to observe thesimultaneous propagation of a shear wave at a multitude of points in a viscoelasticdiffusing medium (1). The inventive method consists in: generating the shear wave byusing a network of transconductors (6) to emit at least one focused ultrasonic

compression wave in the viscoelastic medium; subsequently, using the same network oftransconductors to emit non-focused ultrasonic compression waves at a rapid rate, inorder to produce a series of images of the medium; and processing the images thusobtained in delayed time in order to determine movements in relation to the mediumduring the propagation of the shear wave.
