Intensifying screen Sandwiches a screen film (used for extra-oral radiograph). Intensifying screen absorbs x-ray and transform into visible light which exposes to the screen film.
It exposes film
Crossover EffectA bluring of an image caused by a light reflecting off of one intensifying screen crossing over to another.
reduce the amount of exposure required to produce an image.
Intensifying screens for x-ray film are usually constructed of four distinct layers. A typical screen has a base, reflective layer, phosphor layer and protective coating.
An increase in a film/screen combination increases density. It is a directly proportional relationship.
Technetium is not "radiographic" but it is radioactive.
how to calculate radiographic sensitivity
radiographic involving the urinary system is called;
film screen contact is tested using a special tool called a screen contact test mesh.This coarse wire mesh is laminated in plastic to keep it flat.It is placed on top of the cassette and an exposure is made.
What is radiographic study of the arteries? It is an arteriogram, a graphic image or x-ray of the internal arteries.

Yes, Increased SID = decreased radiographic density. Decreased SID = Increased radiographic density
