O-Arm

The O-arm is an intraoperative imaging system that rotates a full circle around the patient to produce real-time, high-resolution cross-sectional images while surgery is underway. In effect it brings a mobile CT-style scanner into the operating room, so the surgeon can see the exact position of bone, instruments and implants at the moment they are being placed, rather than relying only on images taken before the operation. It is used mainly in spine, brain and nerve, and orthopaedic trauma surgery, where it gives precise guidance for critical steps and supports greater accuracy and safety.
