Med Imag Quizzes

Various questions from Med Imaging Quizzes from 4th Quarter

QuestionAnswer
The photoelectric effect involves the removal (ejection) of an electron. This process of removing an electron from an atom is known as attenuation
When the xray photon strikes an atom within the tissue being imaged and loses all of its energy to an inner shell electron of that atom, the photon is said to have been ___ and undergone the ___ absorbed, photoelectric interaction
When the xray photon strikes an atom within the tissue being imaged and loses only part of its energy to an outer shell electron of that atom, the photon is said to have been ___ and undergone the _____. scattered, compton interaction
The interaction between xray photons and tissue that results in the production of a secondary xray photon is the photoelectric interaction
When the entering xray photon loses energy and changes its path of travel as a result of interacting with an atom, the interaction is known as the compton effect
The outer shell electron that is ejected during the compton interaction is also known as a recoil electron and compton electron
Interactions of low energy xrays (energies below the diagnostic range) with tissue include coherent scattering
At higher kilovoltage, ____ photon interactions occur, resulting in ____ transmission fewer, increased
An incident xray interacts with an atom without ionization during ____ coherent scattering
An outer shell electron is ejected and the atom is ionized during compton interactions
Which xray interaction involves the ejection of the kshell electron photoelectric absorption
compton scatter is directed at _______ angle from the incident beam any
As kVp _____. the probability of the photoelectric absorption ____ increases, decreases
Xrays transmitted without interaction contribute to _________ the radiographic image

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.
