Automatic processing
The processing of radiographs by machine, eliminating the need for human interaction to move the films through the processing solutions; this employs a standardized procedure for processing films as it is basically an automated time temperature method
Clear film
A film that after processing does not show an image
Coin test
A test carried out in the darkroom to test the effectiveness of the safelight
Dark image
A dense or black image
Dark room
A room with controlled lighting where x-ray film is handled and processed
Daylight loader
The device attached to an automatic processor that allows the operator to develop film in ambient light
Dense image
A dark or black image
Developer
The solution used in the processing of exposed x-ray film that softens the emulsion and precipitates silver from the silver bromide crystals of the film emulsion that have been energized by x-rays
Developer cutoff
The blank area on processed radiographs that results from an insufficient level of solution in the darkroom developer tank
Drying rack
...
Electrostatic artifact
Black linear streaks or black spots on the radiograph caused by static electricity
Film hanger
The device that carries the film through the manual processing procedure
Film roller
That part of an automatic processor that moves the film along from one step to another in the automatic processing sequence
Fixer
The solution used in the processing of exposed x-ray film that removes the unaffected silver bromide crystals from the emulsion and hardens the image
Generators
...
Latent image
The term used to describe the x-ray film after it has been exposed; contains the latent image that will be made visible by film processing
Light leak
The area where unwanted white light is entering a darkroom
Light tight
A term used in radiography to indicate that there is no white light exposure
Manual processing
The process of developing radiographs where the film hangers are manually placed in the processing solutions
Overdeveloped
The condition of a radiograph being too dark because of the film's having been left in the developer solution too long
Rapid processing
The processing of radiographs by either elevated solution temperature or concentration, which markedly shortens the time needed to produce an image; used when the time it takes to process the film is shortened and is more important than the exacting of th
Reference film
An ideally processed film which is kept on the darkroom view box,, to which densities and contrasts can be compared to check the strength of the processing solutions
Replenisher
A concentrated form of either the developer or fixer solutions that is used to maintain the volume and concentration of the solutions
Reticulation
An unsatisfactory image caused by a sudden change in temperature from one processing solution to another
Safelight
Illumination used in the darkroom that does not affect the film emulsion
Sight development
A film processing technique in which the time the film stays in the developer is subjectively determined by periodically looking at the developing image under safelight conditions
Stop bath
The solution in which films are placed after the developer
Thermometer
The device found in the developer solution sued to measure the temperature of the solution
Thermostatic valve
A device used to control the temperature of the incoming water in the manual developing tanks
Thin image
A light image, lacking in density
Time temperature technique
A technique used to process x-ray films in which the time the film stay sin the developer is calibrated to the temperature of the solution within a stated acceptable range
Torn emulsion
Film processing error that occurs when the emulsion is removed from the acetate base in a finished radiograph
Underdeveloped film
A thin film that is the result of a weak solutions or incorrect developing time
Visible image
The image present on a radiograph after the film has been processed
Water bath
The second and fourth solutions in the manual processing of dental radiographs
Wet reading
Interpretation of a radiograph approximately 3 minutes after its initial fixation
