WebbIntensifying Screens. A radiographic exposure can be made directly on to photographic film but this requires a relatively long exposure time. It is usual, therefore, for most examinations to use calcium tungstate fluorescent screens which have the property of transforming the invisible X-ray radiant image to a visible blue image. WebbDefinition. 1) Decrease patient motion due to shorter exposure time. 2) Decrease patient exposure level. 3) Decrease scatter radiation level to personnel. 4) Permist use of smaller focal spot size; hence better detail. 5) Increase tube life because of lower mAs required. 6) Permits greater selection in kVp settings.

Webb4 dec. 2024 · Intensifying screens are composed of light-emitting phosphors that fluoresce when exposed to x-rays. Because radiographic film is sensitive to light, fewer x-rays are needed to expose the film. This allows the exposure technique to be reduced, which reduces patient exposure to x-radiation. http://www.sprawls.org/ppmi2/FILMSCR/ biochemical activity
