Nettetintensifying screen, in direct contact with the film during exposure. Since X-ray films are coated with emulsion on both sides, intensifying screens are employed in pairs. Each emulsion surface is placed in close contact with the effective surface of one intensifying screen, to avoid loss of image sharpness. http://www.frankshospitalworkshop.com/teaching_learning/chris/CM%20X-ray%20System%20function%20pp.pptx jesus is given his cross

NettetIntensifying Screen to film contact Free electrons are emitted when lead screen is exposed to X- ray or Gamma- ray. Image’s definition and contrast will deteriorate if there is a gap between the film and screen during exposure due to “stray” electrons. 4.

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. jesus is given all authorityNettetThe intensifying screens converts the remnant radiation to light than produces the latent image. They act as an amplifier of the remnant radiation. 3 Radiographic Intensifying … jesus is god 316 acts 23

"NettetCassettes are used in association with intensifying screens and have related FUNCTIONS: 1. To contain a film 2. to exclude light, 3. to maintain the film in close, uniform contact with both screens during the exposure, 4. to protect the intensifying screens from physical damage.
