Phosphors emit: -
correct answer ✅-Light
What is the fluoroscopic system designed to maintain constant
image intensity called: -
correct answer ✅-Automatic Brightness Stabilization (ABS)
Fluoroscent screen absorbs the x-ray photons and emits light
photons, which immediately come into contact with: -
correct answer ✅-The Photocathode

, RT55 Fluoro Reveiw#2 Exam Questions
And Answers
Why are the Photocathode and Input Phosphor both curved? How
does it affect the distance the electrons travel? -
correct answer ✅-To prevent Fucosing Distortion. All electrons
from Photocathode to Output Phosphor travel same distance
What is electron emission following heat stimulation? -
correct answer ✅-The Thermionic Emission
