Explain the role of collimation in a gamma camera.
Model answer
What a good answer should say
- Collimation in a gamma camera is crucial as it ensures that only gamma photons traveling in specific directions are detected.
- This improves the image quality by reducing the amount of scattered radiation that can blur the image, allowing for more accurate localization of the radioactive tracer within the body.
Explanation
Why this works
This answer effectively addresses the role of collimation by highlighting its importance in enhancing image quality and accuracy in gamma cameras. It tests the understanding of how collimation contributes to the functionality of imaging techniques in medical physics.
