Abstract

Cette invention concerne un dispositif permettant d'examiner des tissus, lequel comprend un capteur qui va produire des signaux en réponse à la pression s'exerçant sur lui lorsqu'il est appliqué contre les tissus. Un vibreur (38) va faire vibrer les tissus, tandis qu'une unité de traitement va mesurer la réponse des structures tissulaires sous-jacentes aux vibrations issues des signaux produits par le capteur. Cette unité de traitement va ensuite établir les différences entre différents types de structures tissulaires sous-jacentes en fonction de cette réponse. L'unité de traitement (35) va déterminer jusqu'à quel point les structures tissulaires sous-jacentes entrent en vibration dans les tissus, ceci en fonction des signaux produits par le processeur. Cette unité de traitement va ensuite établir des différences entre différents types de tissus en fonction de l'étendue de ces vibrations.
