摘要： The invention relates to a method and a device for imaging a visco-elastic medium. The method comprises an excitation step during which an internal mechanical stress is generated in excitation zone and an imaging step of acquiring signals during the movements generated by the mechanical stress in the visco-elastic medium in response to the internal mechanical stress in an imaging zone that includes the excitation zone. According to the invention, the method further comprises a step of calculating a quantitative index associated with the rheological properties of the visco-elastic medium at at least one point of the imaging zone situated at a given depth outside the excitation zone. The quantitative index is representative of a comparison between signals acquired during the movements generated in response to the mechanical stress at at least one point of the excitation zone situated at the given depth, and signals acquired during the movements generated in response to the mechanical stress at at least the point of the imaging zone situated outside the excitation zone.
