O-arm Surgical Imaging System
O-arm® Surgical Imaging with StealthStation® Navigation (PDF, 1.9 MB) provides:
- Speed in the OR: fast access to real-time, multi-plane 3D images (and 2D images)
- Ease in the OR: full support of the unique workflow of spinal procedures
- Safety in the OR: minimized radiation dose for surgical staff
- Confidence in the OR: visualization to confirm hardware therapy placement, potentially eliminating revision surgeries
About the O-arm Surgical Imaging System
The O-arm® Surgical Imaging System is a multi-dimensional surgical imaging platform that is optimized for use in spine, orthopaedic, and trauma-related surgeries. It provides real-time, intra-operative imaging of a patient's anatomy with high quality images and a large field-of-view in both two and three dimensions.
By integrating O-arm surgical imaging technology with Medtronic's StealthStation® surgical navigation systems, surgeons are able to perform less invasive procedures and confirm the precision of advanced surgical procedures before the patient leaves the OR.

O-arm Surgical Imaging System Benefits
| The O-arm System seamlessly integrates with StealthStation navigation. |
Lumbar spine lateral and AP images using the full field-of-view in 2D
- Superior Image Viewing – The O-arm System's large field-of-view and distortion free flat panel technology provide precise image quality for viewing any part of the patient's skeletal anatomy from head to toe.
- Automated Positioning Controls and Workflow – The completely motorized O-arm System and user-friendly controls support quick and easy handling and a smooth workflow. Surgeons can set up and recall up to 4 preferred imaging positions with the touch of a button.
