  • Passive ultrasound needle probe locator
    Patent number: 4431006
    Abstract: A solid steel stylet is carried coaxially within a hollow biopsy needle. The stylet carries a matching layer at its tip, such that when the needle and stylet are inserted into the body, ultrasound energy impinging on the needle tip is converted to pressure waves which are conveyed back up the stylet. An ultrasound transducer located outside the body is coupled to receive sonic energy from the stylet, and to convert it to electrical energy for coordination with, and superposition upon the image of the system.
