An X-Ray Device directs electromagnetic radiation upon a specified region in the body. This radiation tends to pass through less dense matter and absorbed or scattered by denser materials . In Film-Screen Radiography, radiation which has passed through a patient then strikes a cassette containing a screen of fluorescent phosphors and exposes x-ray film. Areas of film exposed to higher amounts of radiation will appear as black or grey on X-ray film while areas exposed to less radiation will appear lighter or white. In Computed Radiography (CR), the x-rays passing through the patient strike a sensitized plate which is then read and digitized into a computer image by a separate machine. In Digital Radiography the x-rays strike a plate of x-ray sensors producing a digital computer image directly.

X-ray film holder is an instrument that allows the X-ray cone to align with the appropriate tooth structure easily and precisely every time. The film holder includes a generally rectangular spine from which a second, film-holding clip projects on one side, and from which the first clip projects on the other side.

X-ray film scanner is designed to meet the needs of picture archiving and communication systems and remote primary diagnosis. It provides enhanced resolution, which is formed by providing a straight-line optical path from an illuminating source, through the X-ray image to be scanned and thence to an imaging lens which forms an image on a CCD array.
