B) attenuate low energy photons
C) allow the passage of low energy photons
D) increase the level of high-energy photons emerging
C) allow the passage of low energy photons
How does the material selected for the anode affect the mean quality?
A) the anode selection shapes the beam by producing characteristic radiation in an acceptable range
B) the anode selection filters the beam by allowing only the necessary low energy photons to emerge from the tube
C) the anode selection shapes the beam by filtering out the high energy photons
D) the anode selection shapes the beam by filtering out the low energy photons
A) the anode selection shapes the beam by producing characteristic radiation in an acceptable range
