A shear wave elastography method for imaging an observation field in an anisotropic medium, including an initial ultrasonic acquisition step during which initial physical parameters are acquired in at least one region of interest； a spatial characterization step during which a set of spatial characteristics of the anisotropic medium is determined on the basis of the initial physical parameter； an excitation substep during which an shear wave is generated inside the anisotropic medium on the basis of the set of spatial characteristics； and an observation substep during which the propagation of the shear wave is observed simultaneously at a multitude of points in the observation field.
