Study Guide Questions with Answers
Which one of the following is not one of the four primary image quality factors? - correct answersC.
Kilovoltage(kv)
The amount of blackness on a processed radiograph is called: - correct answersA. Density
Which of the following exposure factors primarily controls radiographic density? - correct answersB.
mAS
True/False For an underexposed radiograph, the mAs must be increased by a factor of four to produce a
visible change in radiographic density - correct answersFalse
Situation: A radiograph of the knee reveals that it is overexposed and must be repeated. The orginal
technique used 10 mAs. Which one of the following changes will improve the image during the repeat
exposure? - correct answersB. Decrease to 5 mAs
The primary controlling factor for radiographic contrast is: - correct answersB. kV
Situation: Chest radiography requires long-scale contrast. Which set of exposure factors will produce
this? - correct answersC. 110 kV, 2 mAs
Which one of the following sets of exposure factors will produce the highest (short-scale) radiographic
contrast? - correct answersA. 60 kV, 3o mAs
True/False: Kilovoltage is a secondary controlling factor for radiographic density. - correct answersTrue
True/False: A low-kilovoltage technique (50 kV) produces a long scale-contrast image. - correct
answersFalse
Situation: A radiograph of the elbow reveals that it is overexposed. The technologist wants to adjust kV
rather than mAs for the repeat exposure. This is contrary to common practice. The original analog
