question 26 / 50
how does added filtration affect the x - ray beam?
increased quantity, increased quality
decreased quantity, decreased quality
decreased quantity, increased quality
increased quantity, decreased quality

Explanation:

Added filtration absorbs low - energy photons in the x - ray beam. This reduces the number of photons (quantity) but increases the average energy of the remaining photons, thus increasing the quality of the x - ray beam.

Answer:

C. Decreased quantity, increased quality
