Fluoroscopy is a type of medical imaging that shows a continuous X-ray image on a monitor, much like an X-ray movie. It is used to diagnose or treat patients by displaying the movement of a body part or of an instrument or dye (contrast agent) through the body.

During a fluoroscopy procedure, an X-ray beam is passed through the body. The image is transmitted to a monitor so that the body part and its motion can be seen in detail.
