FLUOROSCOPY FINAL EXAM SCRIPT 2026
COMPLETE QUESTIONS AND ANSWERS 100%
CORRECT
◉ Fluoroscopy allows for. Answer: -Imaging of the movement of
internal structures. Can visualize function and motion in real time.
-Commonly used for GI, vascular, and urinary studies, ect.
-This often requires the use of contrast media.
◉ When and by whom was fluoroscopy invented. Answer: -Thomas
Edison.
-1896
◉ What is the typical X-ray tube current in fluoroscopy. Answer: -5 mA
-Can range from .5 to 5 mA
-Compare this to a radiograph which can range from 50-1200 mA.
◉ A, Fluoroscopic system used for dynamic imaging of internal
structures.
B, Major components of an image intensifier.. Answer:
,◉ They used to use (blank) screens. Answer: "Fluoroscopic" screens
◉ Used to require (blank) minutes of dark adaptation.. Answer: "15"
minutes of dark adaptation
◉ (blank) used for night or dim vision have reduced visual acuity.
Answer: Rods
◉ (blank) are used for day vision. Answer: Cones
◉ The (Blank) receives the x-ray beam during fluoroscopy. Answer:
Image Intensifier (ii).
◉ X-rays that exit the patient are (blank) on the ii. Answer: Incident
◉ The ii converts the x-rays into (blank). Answer: High intensity visible
light image.
◉ The ii exists within a (blank) to protect and support it.. Answer: Tube-
glass or metal-housed within a metal structure.
◉ X-rays are (blank) through the glass envelope. Answer: Transmitted
, ◉ They (x-rays) interact with the (blank). Answer: Input phosphor
(cesium iodide)
◉ The energy is converted to (blank). Answer: Visible light
◉ The light intensity emitted by the input phosphor (cesium iodide) is
equal to the intensity of the (blank). Answer: Exit radiation
◉ This light then interacts with the (blank). Answer: Photocathode
◉ The photocathode is composed of (blank). Answer: Cesium and
