QUESTIONS AND
ANSWERS 2026 - 2027
What is the formula for brightness gain - ANSWERS-minification gain
x flux gain
What is the formula for minification gain - ANSWERS-input screen
diameter^2/output screen diameter^2
What is the formula for flux gain - ANSWERS-# of output light photons
/ # of input x-ray photons
How does ABC work in flouro? - ANSWERS-The technical factors are
automatically adjusted to compensate for different thicknesses in the
body. The adjustments maintain the image brightness.

Then interact with the photodiode where the light is converted into an
electric signal
Then they reach the TFT where the electrical signal is collected
How is pulsed fluoroscopy different from continuous fluoroscopy -
ANSWERS-The beam is emitted as a series of short pulses rather than
continuously
How is pulsed fluoroscopy different from intermittent fluoroscopy? -
ANSWERS-Intermittent fluoroscopy is a manual pulsed fluoroscopy
where you are stepping on/off the foot pedal.
How can pulsed fluoroscopy be used to reduce pt dose - ANSWERS-
Reduction in exposure time
