SonoVision Overview

SonoVision is a game changing spinal access technology that successfully applies colored tissue differentiation to ultrasound imaging. As a result, it transforms images that lack meaning for the operative surgeon into clinically relevant, real-time, procedure-enabling access technology.

Seamlessly integrated into the procedural workflow, SonoVision was designed to allow surgeons the ability to accurately differentiate nerve, muscle, and bone while potentially reducing dissection and trauma to the surrounding tissue.

SonoVision™ fulfills the currently unmet need for spinal surgeons utilizing the lateral approach. This device allows for true real-time imaging saving both time and tissue intra-operatively.

Kern Singh, MD
Midwest Orthopaedics at RUSH

SonoVision is an incredible, innovative tool that helps me visualize patient anatomy without causing excess tissue damage. It provides great confidence in avoidance of neural structures and optimizing patient safety and outcomes.

Juris Shibayama, MD
TriStar StoneCrest Medical Center

By providing a more complete picture - through an actual image of the nerve location - SonoVision enables better decision making. For instance, I saw a femoral motor bundle that tested out on EMG but in front was a sensory nerve that SonoVision picked up and EMG did not. I wanted that confirmation and got it. It's impressive.

Andrew Cannestra, MD, PHD
Baptist Health, Jacksonville

SonoVision continues to amaze me especially at L4,5. I’ve been performing Laterals for 15 years and this technology takes the guess work out! Great job TDi solving a problem.
