What is fluoroscopy and how does it work?
Many different exams use fluoroscopy to have a better view of the movement of internal anatomy or material within the body. Fluoroscopy uses a continuous X-ray beam with a special machine called a C-arm.
The C-arm can be used to rotate around a person’s body to create a sequence of images that are projected onto a fluorescent screen, or television-like monitor. When used with a contrast material, which clearly defines the area being examined by making it appear bright white, this special X-ray technique makes it possible for the physician to view internal organs and tissues in motion. Still images are also captured and stored electronically on a computer.
