To increase the speed of an intensifying screen,
A)increase phosphor size.
B)decrease the phosphor layer thickness.
C)decrease phosphor concentration.
D)remove the reflective layer.

Question

Quizplus · Accepted Answer

Increasing phosphor size will increase the brightness and speed of an intensifying screen. This is because larger phosphor crystals have a higher probability of interacting with the x-ray photons and emitting light. However, increasing phosphor size may also decrease spatial resolution.
