X-ray

X-radiation is a form of electromagnetic radiation and was first generated in 1891 by Fernando Sanford, a professor of physics at Stanford University. The use of X-rays for medical purposes was first introduced by Major John Hall-Edwards in Birmingham In 1908.

An X-ray is a radiograph that has been made by projecting X-rays through the body onto photographic film. Certain parts of the body are more radiopaque (allowing fewer X-rays to pass through) than others, and this casts a shadow on the film and creates a picture of the inner workings of the body.

X-rays and cosmetic surgery

An X-ray is required before cosmetic surgery procedures like rhinoplasty and chin lifts to give the surgeon a map of the patient's bone structure. This allows the surgeon to enjoy a clearer view of the skeletal system of the patient than would be afforded through sight alone.

Excessive exposure to X-rays can be damaging, but the radiation exposure is low during a typical X-ray, which is a relatively safe method of investigation with numerous benefits.
