X-rays involves using radiation to capture the image. Different structures have different abilities to absorb the radiation, and this is the fundamental principle driving the technology. Bones absorb greater radiation, and thus appear brighter on the film, whereas the tissue appears light as does not absorb significant rays. This contrasting image thus makes it possible for the doctors to view the internal structures of the body.
