Answer :
The correct option is B. The true statement regarding fluoroscopic systems that use flat panel digital detectors for fluoroscopy is “Flat panel digital detectors have a higher dose efficiency compared to image intensifiers”.
Flat panel digital detectors generally offer superior dose efficiency compared to image intensifiers.
- This means they require less radiation to produce high-quality images, reducing patient exposure.
- Unlike image intensifiers, which use a vacuum tube and a fluorescent screen, flat panel detectors use a direct or indirect conversion process that is more efficient.
- They also provide better spatial resolution and contrast resolution.
- However, flat panel detectors are less prone to image distortion and typically have a longer lifespan, requiring less frequent calibration than image intensifiers.
The other options are incorrect because:
- Option A) Flat panel detectors offer better image quality than image intensifiers, with higher spatial and contrast resolution.
- Option C) Flat panel detectors are less susceptible to image distortion compared to image intensifiers due to their direct digital capture.
- Option D) Flat panel detectors generally have a longer lifespan and are more durable than image intensifiers.
- Option E) Flat panel detectors require less frequent calibration than image intensifiers, as they have more stable and consistent performance.
Final answer:
Flat panel digital detectors have higher dose efficiency and equal or better image quality compared to image intensifiers; they are less prone to distortion, often have longer lifespans, and do not require more frequent calibration than image intensifiers.
Explanation:
The accuracciy of statements regarding fluoroscopic systems that use flat panel digital detectors can be analyzed in relation to their performance and characteristics:
- B) Flat panel digital detectors have a higher dose efficiency compared to image intensifiers.
- Flat panel digital detectors provide equal or better image quality than image intensifiers, not lower.
- Due to their design, flat panel digital detectors are actually less susceptible to image distortion than image intensifiers.
- Flat panel digital detectors typically have a longer lifespan compared to image intensifiers.
- While they may require calibration, the frequency is not inherently more than that required by image intensifiers.
Overall, flat panel digital detectors are a technologically advanced system utilized in modern medical imaging that contributes to improved effiency and durability in fluoroscopic applications.
