How does X-ray dose relate to image quality?.
- A.Higher dose always improves image quality.
- B.Lower dose reduces image quality.
- C.Higher dose can improve image quality but increases risk.
- D.Dose does not affect image quality.
Model answer
What a good answer should say
- Higher dose can improve image quality but increases risk.
Explanation
Why this works
While a higher X-ray dose can enhance image quality by increasing the number of photons reaching the detector, it also raises the risk of radiation exposure to the patient. Therefore, a balance must be struck between achieving sufficient image quality and minimizing dose.
