X-Ray Interactions with Matter Flashcards
Which of the following tissue types is likely to have the greatest number of photoelectric events?
Bone, muscle, soft tissue or fat
Bone
Which interaction, within the diagnostic range, does not involve the removal of an orbital electron?
Classical
A photon of 10 MeV colliding with a nucleus will likely result in what type of interaction?
Photodisintegration
Which kVp will produce the greatest number of photodisintegration events?
None (does not use kVp)
Positive contrast media is administered to a patient to increase what type of interaction?
Photoelectric
Which interaction in the diagnostic range involves the total absorption of the incident photon?
Photoelectric
The ejection of a nuclear fragment is part of which interaction?
Photodisintegration
When the kVp selected is equal to or slightly greater than the inner shell binding energy of a tissue atom, which interaction predominates?
Photoelectric
Secondary photons are also produced during what type of interaction?
Photoelectric
Which of the following is an undesirable contributor to image contrast and density?
Compton
Penetration will result in which shades of the radiographic image?
Dark or Black
Penetration is more likely with which photon energy?
High
Which of the following equates to patient dose?
Penetration, absorption, or scatter
Absorption
Differential absorption involves which interaction?
Photoelectric
T/F: The problem with scatter is that it strikes the image receptor in the wrong place.
True
