OHIO GXMO REVIEW TIPS QUESTIONS AND
ANSWERS SET A+
✔✔Using a higher screen speed and decreased mAs will result in - ✔✔Increased
quantum mottle
✔✔What is the purpose of the film cassette? - ✔✔Prevent light from exposing the film,
prevent marks from scratching and bending the film, provide support for intensifying
screens
✔✔What does wide latitude refer to? - ✔✔The property of a film that allows a large
range of exposures that result in useful film density
✔✔What does FIFO mean? - ✔✔FIRST IN, FIRST OUT. Use the oldest first.
✔✔What is spectral matching? - ✔✔Matching of the color sensitivity of an x-ray film to
the color of light emitted by the intensifying screen
✔✔Information arranged in a series of columns or rows? - ✔✔Matrix

✔✔Too much development can cause a general layer of added gray to the film which is
called - ✔✔Processor Fog
