1. A system for identifying tissue, comprising:
an ultrasound device having a transducer being configured according to computer-executable instructions for projecting ultrasound waves at tissue to cause the tissue to vibrate and produce vibration signatures of the tissue;
a vibration detector being configured according to computer-executable instructions for detecting produced vibration signatures of the tissue, the produced vibration signatures resulting from the projecting; and
a signal analysis processor in communication with the ultrasound device, the vibration detector, and a database, the signal analysis processor being configured according to computer-executable instructions for:
comparing a first produced vibration signature of the tissue with a plurality of vibration signatures stored in the database, wherein each of the plurality of stored vibration signatures corresponds to an ultrasound wave parameter for a known tissue;
determining a degree of similarity between the first produced vibration signature of the tissue and at least a portion of one or more of the plurality of stored vibration signatures,
determining a match between the first produced vibration signature of the tissue and at least one of the plurality of stored vibration signatures when the degree of similarity is above a predetermined threshold, and
identifying the tissue based on the match.
