Chap 5-7 Quiz

QuestionAnswer
If mA is decreased what will happen in the x-ray spectrum the amplitude of the graph will decrease
Which of the following is a major source of occupational exposure? compton interactions
Which interaction, within the diagnostic range, does not involve the removal of an orbital electron? classical scattering
What change will result in changing the Emax of the photons in the x-ray emission spectrum. (Emax = maximum energy) A shift to the right and increase in amplitude
What factor minorly affects the average energy and majorly affects the amplitude of the x-ray emission spectrum? filtration
The colon is imaged during a barium enema examination principally because of differences in subject atomic number
Which of the following x rays would be most likely to undergo classical scattering 5 keV
Positive contrast media is administered to increase which type of interaction? photoelectric
What can be determined from an x-ray emission spectrum photon Emax (Emax =maximum energy)
Anatomic structures that readily transmit x rays are radiolucent
During the Compton effect most of the incident x ray energy is given to which of the following scattered x ray
Which of the following occurs in a Compton interaction an atom is ionized
If filtration is increased what will occur in the x ray spectrum the amplitude of the graph will decrease
Differential absorption between bone and soft tissue occurs principally for which of the following reasons there is a difference in effective atomic number
During photoelectric interaction an electron is emitted from the atom
Differential absorption, although a complicated process, is basically the result of differences between photoelectric effect and transmission

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
