O-arm Surgical Imaging System

O-arm® Surgical Imaging with StealthStation® Navigation 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: 3D Imaging
 

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 navigation

The O-arm System seamlessly integrates with StealthStation navigation.

 
  • Seamless Navigation Integration – By integrating with Medtronic StealthStation surgical navigation systems, the O-arm System reduces X-ray exposure, increasing safety for both OR staff and patients.
  • 2D Imaging and 3D Imaging  – Surgeons can choose simple, low-radiation 2D fluoroscopic images or full 3D reconstructions in standard and high definition.
  • 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.
