Physics

QuestionAnswer
1. X-ray Intensity Number of x-rays in the beam
2. X-ray quantity inversely proportional to the square of the distance from the source (inverse square law).
3. Filtration adding filtration to the useful beam decreases patient radiation dose.
4.mGya measure of the number of ion pairs produced in air by a beam of x-rays.
5.Doubling mAs the number of projectile electrons striking the tube target is doubled, and therefore the number of x-rays emitted is doubled.
6. mAs a measure of the total number of projectile electrons that travel from cathode to anode to produce x-rays.
7.when kVp is doubled x-ray intensity would increase by a factor of 4.
8. 15% increase in kVp should be followed by a reduction of one half in mAs.
9. Attenuation reduction in x-ray intensity that results from absorption and scattering.
10.energy of x-rays measured by the HVL
11.Increasing filtration increases the average energy of an x-ray beam.
12.Filtration has two components: inherent filtration and added filtration.
13. inherent filtration glass or metal enclosure of an x-ray tube filters the emitted x-ray beam.
14.added filtration material between the protective x-ray tube housing and the x-ray beam collimator is a form of added filtration.
15.compensating filter compensates for differences in subject radiopacity.

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.
