What is a consequence of using a more precise collimator in a gamma camera?.
- A.Increased patient radiation dose
- B.Decreased image resolution
- C.Longer imaging time
- D.Higher cost of the imaging procedure
Model answer
What a good answer should say
- Longer imaging time
Explanation
Why this works
Using a more precise collimator can lead to longer imaging times because it allows fewer photons to reach the detector, requiring more time to collect sufficient data for a clear image.
