Artificial X-Ray Imaging System (Axis) – Design And Evaluation On C-Arm Performance In Operating Room And Educational Settings
C-arms (mobile X-ray equipment) provide surgeons with live views of the anatomy during surgery. However, radiation technologists, who operate these C-arms, receive little hands-on C-arm training. As a result, most of their learning curve is carried out during surgery, often causing them to inaccurately position the C-arm. This can slow the procedure down and expose the patient and staff to unnecessary radiation. To address this problem we have developed a system that generates X-rays artificially, without radiation. This artificial X-ray imaging system (AXIS) can guide inexperienced C-arm users during C-arm positioning. We carried out a user study with inexperienced C-arm users and found that they required half the number of X-rays to accomplish simulated imaging tasks when guided by AXIS. AXIS is a promising tool that has the potential to reduce radiation exposure, and improve C-arm positioning efficiency and accuracy in surgical and educational settings.
