| X-ray intensifying screens | Screens which absorb the energy in the X-ray beam that has penetrated the patient and convert this energy into a light pattern which has as nearly as possible the same information as the original x-ray beam. The more light a screen produces for a given input of x-radiation, the less X-ray exposure and thus shorter exposure time are needed to expose the film. In most film-screen systems, the film is sandwiched between two screens in a cassette so that the emulsion on each side is exposed to the light from its contiguous screen. (12 Dec 1998) |

| intensifying screen |
A layer of material placed in contact with the film to increase the effect of the radiation, thus shortening the exposure.

| intensifying screen |
A material used in radiographic production to converts a part of the ionising radiation into light or electrons and that, when in contact with a recording medium during exposure, improves the quality of the radiograph, or reduces the exposure time required to produce a radiograph or both. Also see "Fluorometallic intensifying screen", or "Fluorescent intensifying screen".

| intensifying s. |
a thin sheet of celluloid or other substance coated with a finely divided substance which fluoresces under the influence of x-rays and intended to be used in close contact with the emulsion of a photographic plate or film for the purpose of reinforcing the image.
