3D Needle-Tip Tracking
for Ultrasound-Guided
Procedures
Make complex needle interventions safer, faster, and easier to perform.
The Clinical Problem
Ultrasound-guided needle procedures rely on 2D imaging to navigate 3D anatomy. Clinicians lose sight of the needle tip once it leaves the imaging plane — leading to repeat attempts, misdiagnoses, and complications.

Repeat biopsy rate
Rate of biopsies that need to be repeated
Current 2D ultrasound guidance fails when the needle moves out of the imaging plane. This "blind zone" problem leads to a 30% repeat biopsy rate, increased patient trauma, and longer procedure times — particularly for deep or poorly visualized lesions.
Real-Time 3D Needle-Tip Tracking
Integrated with existing ultrasound systems, our technology provides continuous 3D needle-tip localization throughout the procedure.
Fibre-Optic Needle Transmitter
A low-cost optical fibre is embedded in standard biopsy needles, transmitting ultrasonic signals from the needle tip for precise localization.

Novel Tracking-Imaging Probe
A custom ultrasound probe simultaneously performs conventional imaging and 3D needle-tip tracking — no extra hardware needed.

Real-Time Tracking UI
Clinicians see the needle tip in 3D overlaid on the ultrasound image, enabling off-plane insertions and challenging approaches with confidence.

Why Beacon?
Purpose-built for real clinical workflow — not a research prototype.
3D Tracking
Full off-plane insertion capability. Track the needle tip in three dimensions, even when it leaves the ultrasound imaging plane.
High Accuracy
Sub-millimetre needle-tip localization enables confident targeting of small, deep, or challenging lesions.
Faster Procedures
Reduced procedure time through real-time guidance — fewer needle passes and fewer repeat attempts.
Radiation-Free
No CT or X-ray exposure required. Pure ultrasound-based tracking keeps patients and staff safe.
Cost-Effective
Low-cost fibre-optic needle hardware integrates with existing ultrasound systems — minimal capital expenditure.
What Doctors Say
Direct feedback from clinicians who have evaluated our tracking system.
“This device is extremely useful for less experienced clinicians, helping them gain confidence and improve their performance during ultrasound-guided puncture procedures.”
“The system would be highly beneficial for sampling lesions where needle-tip visualization is difficult.”
“A very useful device and concept, particularly valuable for challenging cases involving deep or poorly visualized lesions.”
“With the tracking system, the entire procedure becomes noticeably easier and faster.”
