When are intensifying screens used? – Frequently asked questions
-
What is an intensifying screen used for?
The intensifying screen converts the x-ray energy into light, which reaches the film and forms the latent image. In dentistry, this type of film is used in panoramic imaging and cephalometric radiography. -
What type of film requires an intensifying screen?
An intensifying screen is used to intensify the x-ray effect during radiation exposure of the x-ray film. -
What is the purpose of intensifying screen in the cassette?
The intensifying screen is placed in a cassette in close contact with a film. The visible light from its fluorescent image will add to the latent image on the film. Its function is to reinforce the action of X-rays by subjecting the emulsion to the effect of light as well as ionizing radiation. -
Why are intensifying screens used quizlet?
What is the purpose of an intensifying screen? To reduce patient dose by using light as a intermedary. -
Where are the intensifying screens attached to?
Intensifying screens are attached to one or both inside panels of the cassette. Screens "amplify" the effect that x-ray photons have on the x-ray film. When an incoming x-ray photon interacts with phosphor crystals contained in an intensifying screen, light is emitted. -
How efficient is an intensifying screen?
The intensifying screen is an energy converter; it converts approximately 5 to 20% of the absorbed x-ray energy into light. This percentage is the conversion efficiency of the screen, and depends on the type of material used in the screen. -
What is the advantage of using screen xray film over Nonscreen film?
a Radiographs made with nonscreen film have greater detail compared with other speed film, because there is no loss of detail from intensifying screens. 296. -
What effect do intensifying screens have on resolution compared to non screen exposures?
Has NO impact on resolution, however. The most accurate factor that measures the speed or sensivity of a screen. Measurement of the amplification of the image that occurs due to the screen's ability to convert x-ray photons to light. Directly related to the conversion efficiency of the phosphor. -
What is the most common widely used radiographic film?
It is made by the remnant radiation exiting the patient and hitting the radiographic film depositing energy into the atoms of the silver-halide crystals. the medium that converts the X-ray beam into visible beam. The most common is photographic film. -
Which of the following types of intensifying screens are used in industrial radiography?
As previously discussed, the common types of industrial intensifying screens are lead screens, fluorescent screens, and fluorometallic screens. -
What are the 2 types of film in radiography?
The two primary types of radiographic film are direct exposure film and screen film. -
How is intensifying screens kept clean?
Intensifying screens should be cleaned periodically according to the manufacturer's instructions. Screen cleaners are ideal for removing dirt, dust and fingerprints and should be done regularly. In dryer climates or the wintertime when there is less moisture in the air, static can become a problem.

A Guide to Radiographic Films and Intensifying Screens
- Summary: A Guide to Radiographic Films and Intensifying Screens Radiographic films are the permanent record where the test result from the radiography test is recorded. The radiographic film provides a permanent visible image of the shadow resulting from the penetrating radiation. The radiography test results are typically recorded on radiographic film, radiographic paper, or electrostatically sensitive paper that is commonly used in the xeroradiography process. Radiographic films are generally…
