Exam-style question
Try this first
How does collimation affect the detection of gamma photons in a gamma camera?.
- A.It increases the number of detected photons
- B.It improves the spatial resolution of the image
- C.It reduces the energy of the photons
- D.It eliminates background radiation
Model answer
What a good answer should say
- It improves the spatial resolution of the image
Explanation
Why this works
Collimation allows only gamma photons traveling in specific directions to reach the detector, enhancing the spatial resolution of the resulting image.
