TEST PREVIEW

  1. Which of the following statements related to the formation of a radiographic image is correct?
  1. All of the following statements related to factors that affect radiographic density are correct EXCEPT which one?
  1. All of the following statements related to source to object distance or thickness of the absorber are correct EXCEPT which one?
  1. Which of the following statements related to radiographic contrast, i.e., the difference in the degree of grayness between areas of the radiographic image are correct?
  1. Which of the following statements related to receptor contrast, i.e., the ability of a receptor to show adequately the information that the photons transmitted through the subject is incorrect?
  1. Factors that affect radiographic contrast include scatter radiation, which will decrease the contrast of the radiograph; however, collimation can counterbalance this effect.
  1. All of the following statements related to contrast resolution are correct EXCEPT which one?
  1. All of the following statements related to special resolution are correct EXCEPT which one?
  1. Which of the following statements related to image magnification is correct?
  1. Which of the following statements related to image distortion is correct?
  1. Image sharpness is considered a major factor in determining image quality as it is the factor that determines the amount of detail an imaging system can reproduce.
  1. Image sharpness is defined by the dimensions of the partially shaded outer region or the penumbra of an object– an image with a narrow penumbra is less sharp.
  1. All of the following statements related to image sharpness are correct EXCEPT which one?
