Fluoroscopic Imaging Exam Questions
And Answers
1896 -
correct answer ✅- First commercial fluoroscope
-Allowed for dynamic radiographic examination.
-Radiation dose was high; image was dim
1950s -
correct answer ✅Image intensifier introduced
-Brightened image and made indirect viewing possible
Image intensified -
correct answer ✅_______ fluoroscopy uses low mA (0.5 - 5 mA)
compared to the mA used in radiographic mode (50 - 1200 mA)
mA -
correct answer ✅Low ______ allows for increased fluoro time
5-
correct answer ✅Control panel includes a timer that buzzes
audibly when _____ min of x-ray fluoroscopic time has been used
,Fluoroscopic Imaging Exam Questions
And Answers
deadman's -
correct answer ✅-The continuous beam is activated using a
_______ switch (releasing pressure applied terminates radiation
exposure
Image intensifier -
correct answer ✅-An electronic vacuum tube that converts the
remnant beam to light, then electrons, then back to light,
increasing the light intensity in the process.
-The input phosphor
-The photocathode
- Focusing lenses
- The accelerating anode
- The output phosphor -
correct answer ✅Image intensifier has 5 basic parts:
Cesium Iodide -
correct answer ✅Input phosphor Originally made of Zinc Cadmium
Sulfide, now made of ______
- Higher atomic numbers absorbed more photons from the primary
beam
