Current Update!!
1. What is absorption in radiography?
Answer: Removal of x-ray photons from the beam due to uptake of their
energy by body tissues
2. What is attenuation?
Answer: Reduction in the number or energy of photons in the primary x-ray
beam after interaction with tissue
3. What is coherent scattering?
Answer: A low-energy interaction (below diagnostic range) in which the
photon changes direction without losing energy
4. What is the Compton effect?
Answer: Scattering interaction in which an incoming photon loses energy
while ejecting an outer-shell electron
5. What is a Compton electron?
Answer: The outer-shell electron ejected during a Compton interaction
6. What is the photoelectric effect?
Answer: Complete absorption of a diagnostic-range x-ray photon by
ejecting an inner-shell electron
, 7. What is a photoelectron?
Answer: The inner-shell electron ejected during a photoelectric interaction
8. What is ionization?
Answer: Removal of an electron from an atom
9. What is secondary radiation?
Answer: Radiation produced as a result of interactions between the primary
beam and matter
10.What is contrast resolution?
Answer: Ability of the imaging system to distinguish between objects with
similar attenuation values
11.What is differential absorption?
Answer: Differences in photon absorption versus transmission among
various tissues
12.What is dynamic range?
Answer: The range of exposure intensities an image receptor can capture
13.What is exit (remnant) radiation?
Answer: The attenuated x-ray beam leaving the patient composed of
transmitted and scattered radiation
14.What is fog in radiography?
Answer: Unwanted exposure that adds no diagnostic value to the image
15.What is transmission?
Answer: X-ray photons passing through the body without interaction
16.What is an image receptor?
Answer: A device that receives radiation exiting the patient
17.What are the two categories of image receptors?
Answer: Film-screen and digital
18.What is a latent image?
Answer: The invisible image on the image receptor prior to processing
