True or False: Radiographic density refers to the overall blackening of the film.
True
False
True or False: Before the introduction of digital radiography, single emulsion films were often used for mammography.
True
False
Which type of fog increases image contrast?
Light Fog
Age Fog
Safelight Fog
Radiation Fog
None of the Above
Which film is most sensitive to handling?
Unexposed & Unprocessed
Exposed & Unprocessed
Exposed & Processed
None, they all have the same sensitivity.
A thin emulsion layer will result in:
Higher resolution
Faster speed
Lower resolution
Which artifact will occur if the humidity is too low in the darkroom?
static
crescent marks
condensation
reticulation
If a white crescent/crinkle artifact is present on a film, when did this artifact occur?
before exposure, before processing
after exposure, before processing
after exposure, after processing
True or False: The three types of static are called: tree, crown and smudge static.
True
False
Which film layer contains silver halide crystals suspended in gelatin?
Base
Emulsion
Adhesive
Supercoat
Which of the following is not a consideration for handling and storage of an unexposed film?
temperature of 20 degrees Celsius or lower
no exposure to light
no exposure to ultrasound
no exposure to radiation
Which type of image is also known as the manifest image?
gurney-mott image
visible image
halide image
latent image
True or False: Fog lowers image contrast.
True
False
Small silver halide crystals will result in:
slower speed
decreased patient dose
lower resolution
faster speed
If a film has a slower speed how will this impact patient dose?
increase to patient dose
decrease to patient dose
no effect to patient dose
True or False: Low contrast films have a short range of greys in the image.
