Fluoroscopy equipment is used to create a continuous X-ray image on a digital monitor. It creates a real-time movie of an X-ray image, which is helpful for seeing how movements occur within the body. This can be achieved with or without a contrast agent. This is a widely used procedure for exams and when diagnosing a condition. It can be used to see the gastrointestinal tract of a patient via barium X-rays, and catheters can be visualized and manipulated to better travel through the body. The technology is also used in orthopedic surgery to help doctors treat fractures and replace joints.
