Equipment Fluoroscopy Test Questions with 100%
Correct Answers
Uses for fluoroscopy: (5)
Surgical procedures
GI system
Cardiovasuclar structures
Placement of catheters/drains/devices
Real-time imaging for functional studies
Fluoroscopy=
Dynamic imaging of the body for active disgnosis
First image taken was with the use of ____
Fluoroscopy
Who developed fluoroscope? And when?
Thomas Edison
1896
Parts of a fluoroscope: (10)
,C-arm configuration
Image tube
Lead drapes
Grid
TV monitor
Bucky slot cover
Spot film device
5 min timer
Last image hold
Dead man switch
Picture of fluoroscope:
Under table unit
The Bucky slot cover (at least 0.25 mm lead equivalence) is engaged by moving the cassette tray
,all the way down towards the feet of the table. It is important to remember to do this prior to a
Fluoroscopy exam because the Bucky slot clover protects the fluoroscopy operators from scatter
radiation during exam.
Spot film cassette holder which allows the operator to take static images on a separate image
receptor during a fluoro exam.
The feet holder accessory attached so that when the table is moved to the vertical position the
patient will have something to stand on
The image intensifier tube is attached to the carriage. The carriage is the arm that supports the
equipment suspended over the table.
All of the fluoro controls are contained on the carriage, but many fluoro units also have a foot
switch which allows the operator to control the fluoro exposures from a distance to decrease the
radiation dose recieves by the operator
Technical factors used in fluoroscopy: (3)
mA= 0.5- 5.0 mA (low because time is so long)
kVp= depends on study
SOD=
• at least 15" for stationary units
, • 12" for mobile fluoro
• ESD can not exceed 10 R/min (100 mGy/min) for fluoro.
• HLF can not exceed 20 R/min (200 mGy/min)
mA parameters used in fluoroscopy=
0.5-5.0 (low mA cause time is so long)
kVp parameters used in fluoroscopy=
Depends on study
SOD parameters used in fluoroscopy= (5)
At least 15" for stationary units
At least 12" for mobile units
ESD can not exceed 10 R/min (100 mGy/min) for fluoro
High level fluoro (HLF) can not exceed 20 R/min (200 mGy/min)
For stationary fluoroscopy units, the SOD must be at least ___
15"
For mobile fluoroscopy units, the SOD must be at least ___
12"
