A device, which performs in-vivo measurement of elasto-mechanical properties of human soft tissue is described. The device permits the controlled application of vacuum to small spots of organic tissue and registers the small deformations caused during the whole measurement process. Deformations are measured in two dimensions (via silhouette) with a vision based technique. The images are grabbed at a rate of 25 Hz and processed in real-time to avoid storage problems. Subsequently, several elasto-mechanical properties of the tissue can be determined via inverse finite element method.
