| 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) |
