About NAVIRFA®
NAVIRFA® Needle Tracking System is designed to reduce complexity and improve accuracy in needle-based interventions for Simpler, Safer and More-Effective procedures.
NAVIRFA® is a “GPS for Needle” during ultrasonic interventional procedures, providing physicians with a precise and easy way for needle placement. NAVIRFA® uses optical tracking technology to continually monitor the 3D position of the needle tip relative to the ultrasound transducer in real-time.
How does it work?

Confidence Outcomes
Usability Testing Report
NAVIRFA® Needle Tracking System was tested by 11 physicians on the phantom and comparing their accuracy between using an ultrasound alone and an ultrasound combined with NAVIRFA®. Each user has 4 attempts; 2 times ultrasound alone and 2 times ultrasound with NAVIRFA®.
● High accuracy, error < 3.0 mm
● Increased hit rate by 60%
● Shorten procedure time
