For ultrasound guided interventional procedures, a tracking sensor is attached on the tail of a needle instrument. Pari-Path surgical navigation system will display a real-time tracked simulated needle with respect to the ultrasound image in a 3D space. No matter if the surgical needle can be clearly displayed or not in 2D Ultrasound image. A treating ellipse area can also be displayed.
