Three-Dimensional Ultrasonic Needle Tip Tracking with a Fiber-Optic Ultrasound Receiver

DOI: 10.3791/57207-v
What you'll learn
  • ✓ Understand fiber-optic ultrasound receiver principles for needle tracking
  • ✓ Localize needle tip position in 3D space relative to imaging probe
  • ✓ Apply real-time tracking in ultrasound-guided minimally invasive procedures
Protocol

Accurate and efficient visualization of invasive medical devices is extremely important in many ultrasound-guided minimally invasive procedures. Here, a method for localizing the spatial position of a needle tip relative to the ultrasound imaging probe is presented.

Difficulty
advanced
Total time
~1–2 hours per procedure (setup + in vivo insertion)

Steps

1
Assemble fiber-optic ultrasound hydrophone setup

Configure the fiber-optic ultrasound receiver system and calibrate detection hardware for spatial positioning. Mount the hydrophone component relative to the ultrasound imaging probe.
