X-ray emission

What affects x-ray quantity x-ray intensity and factors that affect x-ray quality
What affects x-ray quality pebetrability, half value layer, factors tha affect x-ray quality, types of filtration
mAs is quantity of x-rays produced and amount
kVp is quantity of the x-ray, intensity, power
What is x-ray quality the measurement of the number of ion pairs produced in air by a quality of x-rays
Radiation exposure is measured in roentgen(R), milliroentgen (mR), milligrays (mGy)
Factors that affect x-ray quantity are mAs, kVp, distance, and filtration
Factors that affect x-ray quantity (mAs) when the mAs increases the number of x-rays produced increaseswhen the mAs decreases the number of x-rays produced decreases
What are some factors that affect x-ray quality penetrability, half value layer, factors that affect x-ray quality, and types of filtration
what is the quantity and mAs equation I1/I2=mAs1/mAs2I1 and I2 are the x-ray intensity
Factors that affect x-ray quantity (kVp) if the kVp were to bouble, the x-ray intensity would increase by a factor of 4If the kVp were to decrease, the x-ray intensity would decreased by a factor of 4
What is the equation that affects the x-ray quantity (kVp) I1/I2=(kVp1/kVp2)^2
Factors tha affect x-ray quantity (distnace) inverse square law I1/I2=(d2d1)^2
Factors that effect x-ray quality(penetrability) high energy can penetrate more than less energy
What is penetrability the ability of x-rays to penetrate deep through tissue
Penetrability of an x-ray is called x-ray quality
factors that effect x-ray quality (filtration) half value layer 1-5 mm Al placed in the useful beamreduces the number of low energy x-rayreduction in the patient dose
HVL is the best way to specify x-ray quality
Factors that affect x-ray quality (filtration) Inherent filtration (glass window)added filtration (thin sheets of aluminum between the protective x-ray housing and the x-ray beam collimatorcollimator mirror
Inherent+ added filtration = 2.5 mm Al equivalent
factors that affect x-ray quality (compensating filters) helps create uniformity in density when body parts vary inthickness
Types of compensating filters wedge filtertrough filterconic filterbow tie filter

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.
