X-ray Unit
An x-ray unit is the medical equipment used to produce x rays. Because of the risk of over-exposure to x rays, the x-ray unit includes both the machine used for collecting x rays and the protective room within which the x rays are taken and developed.
Film radiographs, or x rays, are the most widely used means of medical imaging. Radiographs are used to examine bones for fractures, growth abnormalities, and joint dysfunctions. X rays are also used to find abnormal growths in the breasts (mammography), other organs and soft tissues; problems in the gastrointestinal tract; circulatory problems such as clogged arteries and blood clots; and a variety of other ailments. Additionally, radiation therapy to treat cancer is generally performed with x rays.
The production of an x-ray image (radiograph) involves three distinct steps: the generation of an x-ray beam, the interaction of that beam with the structures of the patient to be imaged, and the development of the image.
