Fluoroscopy is a type of x-ray technique that uses a fluoroscopy to show deep structures of the body on a monitor. These x-rays capture a moving object of certain organs while they are functioning. It is most often used for studies of the intestinal track. The patient is given barium to drink during the procedure. The barium is used to outline the tissue so it can be visualized on the x-ray. Images will be taken of the area of interest. 

During this process, the patient may be asked to turn from side to side and to hold their breath for short periods of time while the radiologist or technologist capture views from several angles.
