Gone are the days of taking an x-ray with a portable unit, then the technician runs down the corridor and showing up with a film 10 minutes later. Modern day operating rooms involve the presence of on-site fluoroscopic machines. These devices allow for instant x-ray analyses while working. Operations such as Kyphon Balloon Kyphoplasty® (Sunnyvale, CA) utilize two fluoroscopic units. X-rays present in the anterior-posterior and lateral zones simultaneously.
