A tissue examination device includes a sensor which produces signals in response to pressure imposed on the sensor as the sensor is pressed against the tissue. A vibrator (38) vibrates the tissue and a processor detects the response of underlying tissue structures to the vibrations from the signals produced by the sensor, and discriminates between different types of underlying tissue structures based on the response. The processor (35) may determine the extent to which the underlying tissue structures are vibrated within the tissue based on the signals produced by the sensor, and discriminate between the different tissue types based on the extent to the vibration.

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.
