cassette
What are the sizes of the radiographic film?
10x12cm 24x30cm 30x40cm 34x43cm
Does increased SID affect film density?
Yes, Increased SID = decreased radiographic density. Decreased SID = Increased radiographic density
Which radiographic projection has the patient positioned with the back parallel to the film?
anteroposterior
What kind of radiographic film is used for apical pathology?
Periapical Radiographs
What type of radiographic projection has the patient positioned facing the film and parallel to it?

Comperism between geometric unsharpnes and radiographic unsharpness?

What is the relationship between film screen speed and radiographic density?
An increase in a film/screen combination increases density. It is a directly proportional relationship.
What is the density of an unexposed processed radiographic film?
between 0.12 and 0.20. As the film gets older the density will get higher. There is a standard out there that limits the usable film "base fog" density to 0.30.
