Question

1 multiple choice 1 point filtration is the process of eliminating undesirable __ by the insertion of absorbing materials into the primary beam high - energy x - ray photons high - energy incident electrons low - energy x - ray photons low - energy incident electrons 2 multiple choice 1 point filtration permits the radiographer to __ the photon emission spectrum into a more useful beam narrow widen lower increase

Explanation:

1. In x - ray production, low - energy x - ray photons are not useful for imaging and are removed by filtration. High - energy x - ray photons are desired for imaging and low - energy incident electrons are not the target of x - ray beam filtration.
2. Filtration removes low - energy photons from the x - ray beam, which narrows the photon emission spectrum to make the beam more useful for imaging purposes.

Answer:

1. C. low - energy x - ray photons
2. A. narrow
