Abstract
The invention relates to a method and a device for imaging a visco-elastic medium (2). The method comprises an excitation step during which an internal mechanical stress is generated in an excitation zone [A] and an imaging step of acquiring signals during the movements generated by the mechanical stress in the visco-elastic medium (2) in response to the internal mechanical stress in an imaging zone [B] that includes the excitation zone [A]. According to the invention, the method further comprises a step of calculating a quantitative index [Cij] associated with the rheological properties of the visco-elastic medium (2) at at least one point [Bij] of the imaging zone situated at a given depth outside the excitation zone [A].
