CHAPTER 1 OF BONTRAGER TEXTBOOK
OF RADIOGRAPHIC POSITIONING (SELF-
TEST) PART D
Which of the following is not among the four key image quality factors? -
Answer C: Kilovoltage (kV)
The degree of blackness on a processed radiograph is called: - Answer A:
Density.
Which of the following exposure factors significantly affects radiographic
density? - Answer: B. mAS
True/False False. For an underexposed radiograph, the mAs must be increased
by a factor of four to create a discernible change in radiographic density.
Situation: A radiograph of the knee shows that it is overexposed and needs to be
redone. The original approach utilized 10 mAs. Which of the following
improvements will enhance the image during the repeat exposure? - Answer B.
Decrease to 5 mAs.
The key regulating element for radiographic contrast is: - Answer B. kV.
Situation: Chest radiography necessitates long-scale contrast. What set of
exposure conditions will cause this? - ANSWER C: 110 kV, 2 mA
Which of the following sets of exposure settings will result in the maximum
(short-scale) radiography contrast? - ANSWER A: 60 kV, 3o mAs
