Ohio GXMO Exam Questions and
Answers- Vocabulary
Artifacts - Answer-An erroneous portion of an image or tracing that does not accurately represent the
subject of the image or measurement being recorded
Atomic Structure - Answer-
attenuation - Answer-xray beam decreases in intensity as it passes through the patient due to
absorption and scatter
Automatic Exposure Control (AEC) - Answer-An electronic circuit within the x-ray machine that
automatically terminates the exposure time when a predetermined quantity of x-rays has been
detected.
basic biological effects of radiation - Answer-electrocutionradiation burnserythema (Erythema is a type
of skin rash caused by injured or inflamed blood capillaries)anemia (low red blood cell count)leukopenia
(Low white blood cell count)epilation (loss or removal of hair)
beam quality - Answer-
, Beam restrictors - Answer-function to limit the size of the field
In doing so, they limit the volume of tissue irradiated (thereby decreasing the percentage of scattered
radiation generated in the part) and help reduce patient dose.
beam restrictors contrast - Answer-
chemical safety - Answer-
contrast - Answer-difference in tone that makes details visibile
contrast resolution - Answer-
CR - Answer-computed radiography/ digital imaging
X-ray beam intensity - Answer-
density - Answer-
Differences between digital and film - Answer-
Differential attenuation - Answer-The result of differences in transmission of the beam as it passes
through the patient resulting in signal differences to the digital detector
digital basics - Answer-
