GXMO exam prep UPDATED ACTUAL
Exam Questions and CORRECT Answers
Central Ray - CORRECT ANSWER - X-rays at the center of the beam
artifacts - CORRECT ANSWER - dirt , misc items on the x-ray / image or tracing that
does not accurately represent the subject of the image
collimater - CORRECT ANSWER - restricting the size and shape of the radiation beam as
it exits the x-ray tube
atomic structure - CORRECT ANSWER -
attenuation - CORRECT ANSWER - absorption of the x-ray beam in matter, usually the
human body
Control booth - CORRECT ANSWER - secondary protective barrier occupied by imaging
personnel
automatic exposure control (AEC) - CORRECT ANSWER - electronic circuit within the
x-ray machine that automatically terminates the exposure time when a predetermined quantity of
x-rays has been detected
control console - CORRECT ANSWER - where the exposure factors are selected (mA,
time and kVp)
basic biologic effects of radiation exposure - CORRECT ANSWER -
detent - CORRECT ANSWER - lock to prevent movement of the x-ray tube
, Image receptor (IR) - CORRECT ANSWER - the medium that transforms the x-ray beam
into a visible image
beam quality - CORRECT ANSWER - the energy of an x-ray beam
Latent image - CORRECT ANSWER - The invisible image on the x-ray film after
exposure but before processing
beam restrictors - CORRECT ANSWER - changes the shape and size of the primary beam,
located just below the x-ray housing. Ex. cone, collimator
Radiation field - CORRECT ANSWER - area exposed to x-rays based on size and shape of
the collimater
beam restrictors contrast - CORRECT ANSWER -
scatter radiation - CORRECT ANSWER - X-rays scattered back in the direction of the
incident X-ray beam.
chemical safety - CORRECT ANSWER -
contrast - CORRECT ANSWER - difference in density between any 2 adjacent portions of
the image.
upright cassette holder - CORRECT ANSWER - a vertical device to hold cassette and /or
grid
contrast resolution - CORRECT ANSWER - The ability to distinguish very small
differences in tissue densities
