Now, however, a new imaging machine called the 0-arm Scanner is allowing surgeons to visualize spinal surgeries in real time with high-resolution 3D X-Ray images. The scanner, which resembles a narrow MRI machine, consists of a ring-shaped gantry that can be opened and closed to move the patient into position without disturbing their spine. Once the ring is in place, it can be tilted to capture images at angles that would otherwise be impossible to view. During the operation, the surgeon can view live images of their work on a digital flat-panel screen placed adjacent to the ring. The O-arm’s imaging capabilities are particularly helpful when placing hardware in a patient’s vertebrae. “Normally, when you put screws in without the use of this technology, you are guided by the anatomy and your own view of the patient’s spine from previous imaging,” said spinal surgeon Robert Lee of Greater London’s Royal National Orthopedic Hospital in a recent interview. “With the O-arm Scanner you get a real-life 3D model. The camera enables you to put the screws in exactly where they should be. It is extremely precise.” During an operation, the scanner can spin 360 degrees around a patient and capture nearly 400 images in just 13 seconds. It also utilizes low-dose X-ray imaging to minimize the risks associated with radiation exposure. Although the O-arm is currently only available in a few specialized surgery departments, it could become the new imaging standard for spinal surgeons before too long.
