Fluoro QC Exam Questions With Complete Solutions
10 Correct Answers The max amount of lag should be less than
___ % for cardiac, vascular, and interventional studies because a
0.014 inch moving guide wire must be visualized
100 Correct Answers For max. fluoro exposure rate, must not
exceed ___ mGy/min at low dose rate setting with automatic
intensity control
150 Correct Answers For max. fluoro exposure rate, must not
exceed ___ mGy/min at high (level irradiation control activated)
dose rate setting with automatic intensity control
20 Correct Answers The maximum amount of lag should be
less than ____% for GI studies
20-24 (center) and 20 (edge) Correct Answers What are the
limits for the normal mode of High Contrast Resolution?
30-35 (center) and 24-30 (edge) Correct Answers What are the
limits for the magnification mode of High Contrast Resolution?
50 Correct Answers For max. fluoro exposure rate, must not
exceed ___ mGy/min when equipment does NOT have
automatic intensity control
ABC (intensity/stability) Correct Answers To assure that the
automatic brightness control
of the fluoroscopic unit is functioning properly
, ABC (Limits) Correct Answers The dose rate (mGy/sec) for
one block should be approximately half the value for the two
blocks
The light output of the monitor should be fairly similar for both
exposures
ABC (procedure) Correct Answers Place two aluminum blocks
on tabletop
Place dosimeter (upside down) on top of blocks
(over-table tube) (so x-rays go through dosimeter before blocks)
Measure dose rate
Measure light at monitor with light meter
Remove one aluminum block
Measure dose rate
Measure light at monitor with light meter
