OHIO GXMO EXAMINATION PREP STUDY
GUIDE LATEST UPDATED PRACTICE
SOLUTION VERIFIED 100 PERCENT
◉ 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:
