AND CORRECT VERIFIED ANSWERS/ ALREADY
GRADED A+ (BRAND NEW!!)
1. The major reason that image intensified fluoroscopy is
employed is that it allows for:
• A) Rapid film development
• B) Dynamic viewing of moving structures
• C) Higher spatial resolution than radiography
• D) Lower patient dose than any other modality
Correct Answer: B
Rationale: Image intensification converts low-intensity x-rays into
a bright visible light image, enabling real-time dynamic
visualization of anatomical motion (e.g., swallowing, cardiac
1
,contraction). This is the primary advantage over conventional
static radiography .
2. Portable intensified fluoroscopy used for diagnostic purposes
must not exceed which exposure rate at the tabletop?
• A) 1 R/min
• B) 3 R/min
• C) 5 R/min
• D) 10 R/min
Correct Answer: C
Rationale: California regulations limit portable fluoroscopic
equipment to 5 R/min at the tabletop for diagnostic procedures.
Fixed units typically have a limit of 10 R/min, with a high-level
control option allowing up to 20 R/min with an audible alarm .
3. Which type of vision is most commonly employed during
conventional fluoroscopic exam?
2
, • A) Photopic (cone) vision
• B) Scotopic (rod) vision
• C) Mesopic vision
• D) Lovotopic vision
Correct Answer: A
Rationale: Photopic vision uses cones in the retina and functions
under bright light conditions. Since image intensifiers produce a
bright output image, the operator uses photopic vision rather
than scotopic (night) vision .
4. As the illumination of the light source increases, visual acuity:
• A) Increases
• B) Decreases
• C) Remains the same
• D) Fluctuates randomly
