What is the primary purpose of collimation in a gamma camera?.
- A.To increase the intensity of gamma rays
- B.To improve the spatial resolution of the image
- C.To reduce patient exposure to radiation
- D.To enhance the detection of low-energy photons
Model answer
What a good answer should say
- To improve the spatial resolution of the image
Explanation
Why this works
Collimation in a gamma camera is used to ensure that only gamma rays coming from a specific direction are detected, which improves the spatial resolution of the resulting image. This is crucial for accurate imaging in medical diagnostics.
