Main characteristics of radiological intensifying screens were measured. Speed and definition under conditions described before. The different screens-film systems were ranged after their speed factor, at 40, 70 and 120 kV with mention of definition of these systems when measured. Afterglow and abrasion resistance were measured under experimental well definite conditions. Results show that are extant rare earth screens allowing a decrease of X-ray exposure without too great afterglow or mechanical frailty.

UI MeSH Term Description Entries
D008674 Metals, Rare Earth A group of elements that include SCANDIUM; YTTRIUM; and the LANTHANOID SERIES ELEMENTS. Historically, the rare earth metals got their name from the fact that they were never found in their pure elemental form, but as an oxide. In addition, they were very difficult to purify. They are not truly rare and comprise about 25% of the metals in the earth's crust. Rare Earth Metal,Rare Earth Metals,Earth Metal, Rare,Earth Metals, Rare,Metal, Rare Earth
D011856 Radiographic Image Enhancement Improvement in the quality of an x-ray image by use of an intensifying screen, tube, or filter and by optimum exposure techniques. Digital processing methods are often employed.

D014963 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.
