X-ray final flashcard

Front

kVp determines the ________________ of the x-ray photons.

Back

Quality

Front

The __________ rule of x-ray states that a 15% increase in kVp is equivalent to doubling the mAs.

Back

15%

Front

__________ filtration exists due to how it is made.

Back

Inherent

Front

The overall effect of filtration is that quality goes up, quantity goes _______________.

Back

down

Front

Scatter radiation from the ________________ is the primary cause of occupational radiation exposure.

Back

Front

What is the primary purpose of x-ray filtration?

Back

To improve image quality by removing low-energy photons.

Front

Define the term 'mAs' in the context of x-ray imaging.

Back

mAs stands for milliampere-seconds, a measure of the total x-ray exposure.

Front

What is the relationship between kVp and image contrast?

Back

Higher kVp results in lower image contrast.

Front

What is inherent filtration in x-ray tubes?

Back

Filtration that occurs naturally due to the materials in the x-ray tube.

Front

What effect does increasing kVp have on patient dose?

Back

Increasing kVp generally reduces patient dose.
