Exam-style question
Try this first
Explain how gamma photons are detected in a gamma camera.
Model answer
What a good answer should say
- Gamma photons are detected in a gamma camera using a scintillation crystal that converts the energy of the gamma photons into visible light.
- This light is then detected by photomultiplier tubes, which convert the light into electrical signals that can be processed to create an image.
Explanation
Why this works
This answer is strong because it clearly outlines the detection process of gamma photons, highlighting the role of the scintillation crystal and photomultiplier tubes. The question tests the understanding of the components and functioning of a gamma camera.
