ABSTRACT:
A tissue examination device includes a plurality of sensors, each of which produces a signal in response to pressure imposed on the sensor in accordance with the properties of different types of underlying tissue structures as the sensor is pressed against the tissue. A plurality of processing tests are performed on the signals, and the different types of the underlying tissue structures are discriminated from each other based on the results of the tests.
