O-arm Surgical Imaging System Accessories

StealthStation Navigation System Integration

The O-arm^® Surgical Imaging System seamlessly interfaces with the StealthStation^® Navigation Systems to provide surgeons with real-time information about the patient's anatomy in as little as 55 seconds.*

Save Time in the Operating Room

• Automatic data transfer of patient's 3D set, as well as the AP and lateral images
• Automatic patient registration on the StealthStation Navigation System eliminates the need for lengthy patient registration and allows the surgeon to navigate within 55 seconds* after image acquisition
• Acquisition of additional 3D data sets whenever needed during surgery, making navigation easy to use, more effective and reliable
• A user-friendly interface that is streamlined to fit the workflow in the OR and to support the surgeon's work

Detail - 55 seconds* to navigation

Sample Timeline in the Operating Room

• 15 seconds* – For O-arm System 3D image acquisition
• 30 seconds* – For 3D reconstruction to be displayed on the O-arm System Mobile View Station
• 55 seconds* – For image data to be automatically transferred to the StealthStation Navigation System, enabling the surgeon to navigate

* As measured in standard definition mode using O-arm System Software release 3.0.3 and StealthStation System with Spine Software release 1.4. Your times may vary.

2D Imaging: O-arm Surgical Imaging System

The O-arm^® Surgical Imaging System flat panel detector acquires 2D images that are three times bigger than a 9'' standard C-arm, simplifying the treatment of larger fractures.  Robotics allow for easier positioning AP to Lateral and when using wag.

The O-arm System Smart Position Memory

The programmable memory stores the preferred position of the O-arm system gantry and detector as well as any X-ray technique, in up to four imaging positions. This allows the surgeon to recall the preferred image position at the touch of a button any time during surgery, eliminating time-consuming repositioning and additional X-ray exposure for scouting.

3D Imaging: O-arm Surgical Imaging System

A full 360° 3D scan can be performed in just a few seconds thanks to the closed gantry of the O-arm^® System. The scans can provide 3D information on a patient's changing anatomy during surgery and confirms precise hardware and implant placement before closing the patient. This extra, on-demand information can help surgeons improve patient outcomes.

Superior 3D Image Size and Quality

The O-arm System's scanned volume of 3D reconstructions is three times bigger than that obtained from any standard 3D C-arm. The large image volume allows surgeons to:

• Capture the entire cervical spine in one 13-second scan
• Reduce the need for re-centering
• Comfortably handle cases where large areas need to be visualized

Two Levels of 3D Image Acquisition

• In the 3D mode, the O-arm System offers two levels of image acquisition using a 512 x 512 x 192 reconstruction matrix
• Standard Definition 3D Imaging Mode: Exposure time ~ 13-second scan time taking 391 images over 360°
• High Definition 3D Imaging Mode: Exposure time ~ 26-second scan time taking 750 images over 360°, with better contrast and spatial resolution

O-arm Surgical Imaging System: Image Viewing

The O-arm Surgical Imaging System – Mobile Image Viewing System

The superb image quality of the O-arm^® System is based on the use of distortion-free flat panel technology. The state-of-the-art 30 cm x 40 cm flat panel detector with 3 Mega-pixels (1.5 k x2 k) provides sharp resolution and a high dynamic range for greater precision. These features allow the surgeon to quickly obtain crucial visibility to any part of the patient's skeletal anatomy during image-guided surgery.

O-arm System Image Viewing Components and Features

• Image Display – Images are displayed on the large, 30" digital flat screen of the O-arm System Mobile View Station, providing the surgeon with excellent visibility from the operative field.
• Viewing Options:
  • 3D orthogonal and oblique
  • 2D views
  • MIP (Maximum Intensity Projection)
  • Surface rendering
  • Digital light box views
• Wireless Mouse – Surgeons have total view control from the surgical field with the wireless, sterile surgeon mouse.
• Network Interface – The O-arm System is fully DICOM 3 compatible for simple transfer of O-arm System data to the hospital network. Alternatively, a USB stick or a CD/DVD ROM can be used.
• Powerful Generator – By combining the flat panel detector with a powerful 32 kW generator, the O-arm System enables imaging of heavier patients and hard-to-image anatomy, such as the cervical-thoracic junction and pelvic region.

Detail - The O-arm Surgical Imaging System Pendant

The O-arm^® Surgical Imaging System optimally supports the surgical workflow and creates a controlled surgical environment through the following automated positioning controls and user-friendly features:

• Robotic Controls for Easy Beam Positioning – All motions of the O-arm System gantry and source-detector unit are motor controlled. This feature gives surgeons full mobility for easy positioning and lateral patient access when they need it.
• Multiple Draping Options for Uncompromised Sterility – Multiple draping options exist, including several custom drapes for easy and fast draping. The O-arm System's closed gantry is designed to stay sterile during the whole procedure, eliminating parts moving in and out of the sterile field.
• Simple, Intuitive Control Panel for Ease-of-Use – The O-arm System's central control panel (pendant) allows the operator to control all motions and X-ray settings at the touch of a button. An identical second control panel can be draped and used within the sterile field to give the surgeon full access.
• Smart Position Memory to Remember Your Preferred 2D Views – The programmable memory stores the preferred position of the O-arm System's gantry and detector as well as any X-ray technique, in up to four imaging positions. This allows the surgeon to recall the preferred image position at the touch of a button any time during surgery.
