| thin film | <radiobiology> Plasmas are often used to deposit thin-film coatings on various materials. (09 Oct 1997) |
| kub film | An X-ray showing the kidney, ureter, and bladder. This is in reality a plain abdominal x-ray and includes other structures such as the diaphragm above and the pelvis below. (12 Dec 1998) |
| film | 1. A thin skin; a pellicle; a membranous covering, causing opacity; hence, any thin, slight covering. "He from thick films shall purge the visual ray." (Pope) 2. A slender thread, as that of a cobweb. "Her whip of cricket's bone, the lash of film." (Shak) Origin: AS. Film skin, fr. Fell skin; akin to fylmen membrane, OFries. Filmene skin. See Fell skin. To cover with a thin skin or pellicle. "It will but skin and film the ulcerous place." (Shak) Source: Websters Dictionary (01 Mar 1998) |
| film, ap | An X-ray picture in which the beams pass from front-to-back (anteroposterior). As opposed to a PA (posteroanterior) film in which the rays pass through the body from back-to-front. (12 Dec 1998) |
| 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) |
| film dosimetry | Use of a device (film badge) for measuring exposure of individuals to radiation. It is usually made of metal, plastic, or paper and loaded with one or more pieces of X-ray film. (12 Dec 1998) |

| film, pa | An X-ray picture in which the beams pass from back-to-front (posteroanterior). As opposed to an AP (anteroposterior) film in which the rays pass through the body from front-to-back. (12 Dec 1998) |
| 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) |
| film speed |
The relative light sensitivity of the photographic emulsion (film). Expressed in ISO (International Standards Organisation) (ASA on older cameras), the film speed, or sensitivity to light, increases with the number. For example, an ISO 100 film requires less light than an ISO 50 film. Each time you double the film speed, half as much light is needed for a correct exposure. Faster films need less light but they produce grainier pictures. ...
