QuestionAnswer
Intensity is the what? The total energy contained in the x-ray beam in a specific area at a given time
Intensity is affected by what? The kilovoltage, milliamperage, exposure time, and distance.
The inverse square law is used to explain what? How distance affects the intensity of the x-ray beam
What is placed in the path of the x-ray beam to reduce the intensity and remove the low-energy x-rays from the beam ? An aluminum filter
The thickeness of aluminum placed in the path of the x-ray beam that reduces the intensity by half is termed what? Half-value layer
Quantity refers to what? The number of x-rays produced and is controlled by the milliamperage
Increased kilovoltage produces x-rays with what? Increased energy, shorter wavelength, and increased penetrating power
Kilovoltage affects what? Density and contrast
Quality refers to the what? Mean(average) energy or penetrating ability of the x-ray beam and is controlled by the kilovoltage
Exposure time also influences what? The number of X-rays produced
Amperage determines what? The amount of electrons passing through the cathode filament
Milliamperage regulates the temperature of the what? Cathode filament
The overall darkness or blackness of an image is called what? Density
The term that describes how dark and light areas are differentiated on an image is called? Contrast
If the target receptor distance is doubled, the resultant beam will be? One fourth as intense
Current kilovoltage range for dental X-ray 60-70 kV
Current milliamperage range used for dental X-rays ? 60-8 mA

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.
