| 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.

| 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) |
