| chest film | most common X-ray used to detect abnormalities in or within the thoracic cage, such as the lungs, heart, aorta, and the bones of the chest. Extra metallic objects, such as jewelry are removed from the chest and neck areas for a chest X-ray to avoid interference with x-ray penetration and improve accuracy of the interpretation.

| right or left lateral decubitus film | A radiograph exposed with the subject in the decubitus position; named for the side that is dependent. Synonym: right or left lateral decubitus film. (05 Mar 2000) |
| plain film | A radiograph made without use of a contrast medium. (05 Mar 2000) |
| wide-latitude film | Film that does not show large contrast differences with differences in exposure; the slope of the H and D curve is low. Synonym: latitude film. (05 Mar 2000) |
| precorneal film | A protective film, 7 to 9 nm thick, consisting of external oily, intermediate watery, and deep mucoprotein layers. Synonym: tear film. (05 Mar 2000) |
| X-ray film | A film base coated with an emulsion designed for use with X-rays. (12 Dec 1998) |
| scout film | A radiograph exposed before contrast medium is given, such as the preliminary film for an angiogram, urogram, or barium contrast gastrointestinal examination. Synonym: scout radiograph. (05 Mar 2000) |
| screen-film contact | The closeness and uniformity with which the X-ray film in a cassette lies against the screen. Image resolution is dependent on this closeness and uniformity of contact. (05 Mar 2000) |
| horizontal beam film | A radiograph made with the central axis of the X-ray beam parallel to the floor, able to show an air-fluid level. (05 Mar 2000) |
| serial film changer | A device that moves film for radiographic studies that require rapid serial X-ray exposures, such as angiography. Synonym: rapid film changer, serial film changer. (05 Mar 2000) |
| spot film | A radiograph made during the course of an examination under fluoroscopic control, with a device attached to the fluoroscope. (05 Mar 2000) |
| spot-film radiography | An X-ray of a localised region, usually under study by fluoroscopy. (05 Mar 2000) |
| decubitus film | A radiograph exposed with the subject in the decubitus position; named for the side that is dependent. Synonym: right or left lateral decubitus film. (05 Mar 2000) |
| tear film | A protective film, 7 to 9 nm thick, consisting of external oily, intermediate watery, and deep mucoprotein layers. Synonym: tear film. (05 Mar 2000) |
