Adding the Online Images that Surgeons Need Most and Currently Do Not Have




Robustness of the VUZE System is assessed when registration of the intra-operative X-Rays with the pre-suregery CT scan is challenging. For example, when newly-placed implants are present in the X-Ray images, or when the X-Ray images are generated with low-dose radiation.


VUZE displays critical cross-sectional views that are currently unavailable during X-Ray guided surgery. It overlays instantly the positions and trajectories of surgical tools seen in standard intra-operative 2D X-Ray images onto cross-sections generated from a standard pre-operative CT scan. Further facilitating this workflow, only top-view (a.k.a. AP) X-Rays are required.





Before Surgery


What the Surgeon Sees 

In Surgery

Safe tool insertions into a vertebra, the best view is a cross-section

Standard 3D CT scan, incl. cross-sections, for diagnosis and planning

Tool insertion into a vertebra

Tool in 2D X-Ray image

(no cross-sections)


What the Surgeon Sees 

Tool and trajectory are detected in X-Ray image and placed on a matching CT cross-section


The only hardware added by VUZE in the OR is an on-cart, off-the-shelf PC and a touchscreen.  The simplicity and affordability of common X-Ray guidance are both maintained. As for tool neutrality/specificity, it may be configured by software (if desired).

FDA 510(k) is currently pending.

In Development

Simulated Radiation-Free Views: During C-Arm movement, a real-time sequence of simulated 2D views is displayed continuously. Those are generated by VUZE from pre-operative CT and correspond to current C-Arm positions. As a result, acquiring an actual X-Ray image may typically be deferred until a desired simulated view has been identified by the surgeon.


Precision of the VUZE™ System is evaluated by viewing, side by side, the cross-sectional images displayed by VUZE during tool insertion and the images generated afterwards by a new post-insertion 3D scan. For each pedicle along the thoracolumbar spine, two pairs of corresponding cross-sections (axial and sagittal) are displayed.
