A radio-fluoroscopy (R/F) system is a medical imaging device that uses an X-ray beam to create a continuous image of the inside of the body on a monitor: 
 
Radio-fluoroscopy system
What it does
Creates a continuous X-ray image of the inside of the body on a monitor
How it works
Passes an X-ray beam through the body and transmits the image to a monitor
What it's used for
Diagnosing problems and guiding treatment procedures
What it shows
Moving internal organs and tissues in real time
What it can show
Many body systems, including the skeletal, digestive, urinary, respiratory, and reproductive systems
Fluoroscopy is similar to an X-ray "movie", while standard X-rays are like still photographs. Healthcare providers use fluoroscopy for a variety of purposes, including: 
Diagnosing problems 
Guiding treatment procedures, such as surgeries and catheter placements 
Evaluating specific areas of the body, including bones, muscles, joints, solid organs, and more 
Some examples of R/F systems include:
Zexira i9
A flexible fluoroscopy system that can support a wide variety of examinations and procedures 
Cios Select VA21 II
A mobile, digital fluoroscopy system that requires specific precautions for use, including radiation protection measures, dedicated training, and a service contract
