Popis: |
Digital holography enables the capture of phase and amplitude from a single camera frame with high sensitivity. Displacements induced by a shear-wave diffuse field are acquired at the surface of a scattering sample. From the acquisitions, the stiffness of the sample can be mapped using a time-reversal-based algorithm. The coupling of digital holography with a time-reversal method achieves full-field quantitative elastography without the need of a controlled or synchronized source of mechanical wave. We present here the validation of the method on tissue-mimicking polymer samples and latest results on ex-vivo and in-vivo biological samples. |
