Abstract:

In this work the shear elasticity of soft solids is measured from the surface wave speed estimation. An external source creates mechanical waves in the audible frequency range. Surface waves are detected using acoustic sensors. The surface wave speed estimation is extracted from the complex reverberated elastic field through a time‐reversal analysis. These quantitative measurements in a hard and a soft gelatin‐based phantom are validated by independent transient elastography estimations. In contrast with other quantitative elasticity assessment methods, one advantage of the present approach is that it is based on a low cost sound technology. Moreover, the robust and simple experiments performed in cheese and soft phantoms, allows thinking of applications in food industry and medicine.
