Abstract

The inventive imaging method consists in generating a mechanical wave having shearing and compressional components in a viscoelastic medium and in determining the movement parameter of said viscoelastic medium at different points during the propagation of said mechanical wave. Said method comprises a correction stage when the movement parameter is processed for eliminating errors caused by the compressional component of the mechanical wave.
