The O-arm™ O2 Imaging System is a mobile x-ray system designed for 2D fluoroscopic and 3D imaging for adult and pediatric patients weighing 27kg or greater and having an abdominal thickness greater than 16cm, and is intended to be used where a physician benefits from 2D and 3D information of anatomic structures and objects with high x-ray attenuation such as bony anatomy and metallic objects. The O-arm™ O2 Imaging System is compatible with certain image guided surgery systems.


The O-arm™ system’s high quality, versatile imaging provides the information you need to guide your clinical decision making.


Along with StealthStation navigation, the O-arm™ system provides enhanced 3D visibility and surgical feedback. It also:

  • Provides current patient data in the OR
  • Enables advanced surgical approaches like MIS
  • Provides additional information in challenging procedures, like heavier patients or patients with unusual anatomy1,2,3
  • Automatic registration keeps the process simple

The O-arm™ system also offers options for workflow efficiencies, such as:

  • In procedures where pre-op axial/coronal/sagittal slice data is necessary, it may be possible to use the O-arm™ system to provide the initial data set
  • Eliminating the need to send patients to be scanned in radiology



The O-arm™ system provides flexibility for surgeons to achieve As Low As Reasonably Achievable (ALARA). Multiple image protocols allow the surgeon flexibility to choose the appropriate dose to the patient based upon individual clinical objectives.4






With opportunities to reduce dose to the surgeon and staff, the O-arm™ and StealthStation systems eliminate the need to wear lead protective apparel during the navigated steps of the procedure.5,6



Surgical Workflow

The O-arm™ system has been designed to complement the surgical workflow with:

  • Multiple surgical table options
  • Inter-room mobility for concurrent cases
  • On-demand imaging, no need to schedule in advance
