QuestionAnswer
Tungsten is used to coat the anode disc because it has a high atomic number.
The best situation for less heat production and a quality image is to have a: large actual focal spot and small effective focal spot.
The advantage to using a larger actual focal spot is higher exposures can be used.
With a rotating anode, the focal spot becomes a focal track.
The size of the actual focal spot depends on the size of the cathode filament being used.
The effective focal spot is the origin of the x-ray beam as seen from below the tube.
Molybdenum is a poor thermal conductor.
The primary advantage of a rotating anode is that it allows greater heat capacity at the anode.
The relationship between the actual focal spot size, effective focal spot size, and anode target angle is called the line-focus principle.
One of the reasons that molybdenum is used in rotating anodes is because it is light but strong.
Which primary exposure factor influences both the quantity an quality of x-ray photons? kVp
Characteristic photons are represented by a __________ emission spectrum and Bremsstrahlung is represented by a _____________ emission spectrum. discrete; continuous
At 100 kVp, the radiation produced is : 15% characteristic and 85% bremsstrahlung
Total filtration in the x-ray beam includes_______. Inherent filtration Added filtration
Which type of target interaction is responsible for most of the x-rays in the diagnostic beam? breamsstrahlung
This interaction involves a cascade similar to dominos falling. characteristic
What percentage of the kinetic energy is converted to X-rays when moving electrons strike the anode target? 1
According to the line focus principle, as the target angle decrease, the _________. effective focal spot size decreases

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:
