generation. - correct answer ✔✔Properties of the x-ray imaging system that
influence the selection of exposure factors are reviewed, including ____
radiographic technique - correct answer ✔✔described as the combination of
settings selected on the control panel of the x-ray imaging system to produce a
high-quality image.
The geometry and position of the x-ray tube, the patient, and the image receptor -
correct answer ✔✔radiographic technique includes:
exposure factors - correct answer ✔✔The factors that influence and determine
the quantity and quality of x-radiation to which the patient is exposed are called
____
mGya or mGya/mAs (mR or mR/mAs) - correct answer ✔✔radiation quantity
refers to radiation intensity measured in ____
x-ray beam penetrability - correct answer ✔✔radiation quality refers to ____
,half-value layer (HVL). - correct answer ✔✔radiation quality refers to x-ray beam
penetrability, best measured by the____
2 - correct answer ✔✔focal-spot size is limited to____ selections
kVp and mAs - correct answer ✔✔factors principally responsible for x-ray quality
and quantity.
Focal-spot size, distance, and filtration - correct answer ✔✔____are secondary
factors that may require manipulation for particular examinations.
penetrate the anatomy of interest. - correct answer ✔✔A higher quality x-ray
beam is one with higher energy that is thus more likely to ____
kVp - correct answer ✔✔____controls screen-film radiographic contrast.
kVp - correct answer ✔✔The ____ has more effect than any other factor on image
receptor exposure because it affects beam quality and, to a lesser degree,
influences beam quantity.
increased kVp;
reduced - correct answer ✔✔____interact more by Compton effect and produce
more scatter radiation, which results in ____image contrast.
, differential absorption or contrast - correct answer ✔✔as kVp increases, less
____occurs.
mA - correct answer ✔✔The ____selected determines the number of x-rays
produced and therefore the radiation quantity.
ampere (A). - correct answer ✔✔the unit of electric current is the ____
1 coulomb (C) - correct answer ✔✔One ampere is equal to ____
