Beam Restrictors
100
Also known as the foundation of radiographic film
What is the base?
100
2 shutters, upper and lower
How many shutters are in the collimator?
100
Occurs when fixer gets into developer
What is contamination
100
replenishment system
What replaces depleted chemicals in the automatic processor?
100
kVp and the amount of irradiated material
What are the factors that affect amount of scatter?
200
The primary purpose of this layer of film is to bind the emulsion to the base
What is the adhesive layer?
200
5.9 is the z # of this material
What is fat?
200
This hardens the emulsion and reduces the swelling of the emulsion
What is the hardener
200
The 2 steps involved in archiving the image
What is washing and drying
200
As kVp increases, this interaction with matter increases
What is the Compton scatter interaction?
300
This layer is made up of gelatin and silver halide crystals
What is the emulsion?
300
7.4 is the z # of this material
What is soft tissue?
300
restricts reducing action so unexposed silver halide crystals are not reduced
What is the restrainer in the developer
300
needs an acidic environment
What is the fixer
300
As scatter increases it does this to the scale of contrast contrast
What is long scale, low contrast
400
This layer reduces damage from scratches, pressure, or contamination during storage, handling, and processing
What is the supercoat?
400
13.8 is the atomic # of this material
What is bone?
400
Clears image by removing unexposed silver halides from emulsion;stops development
What is fixing
400
Comes in varying forms, however, the inner structure takes on a cubic form or cubic lattice
What is the silver halide crystal?
400
As kVp decreases this interaction increases
What is photoelectric absorption interaction
500
crystal production, ripening, mixing and coating
What are the 4 stages of film manufacturing
500
Size of part being imaged and desired contrast scale determines this technical factor
What is kVp
500
ammonium thiosulfate
What is the clearing agent in the fixer?
500
Must have impurity added to attract the free silver ions during latent image formation
What is sensitivity speck
500
Decreasing the field size, decreases the scatter and does this to the scale of contrast
What is short scale, high contrast
