摘要：
A sensor is mounted to a needle at a location proximate to a tip of the needle. The sensor senses tissue density of tissue in contact with the tip as the needle passes through the tissue. Further, the sensor detects a change in tissue density as the tip passes from one tissue to a target tissue.
