What is the primary method by which gamma photons are detected in a gamma camera?.
- A.Photomultiplier tubes convert gamma photons into electrical signals
- B.Gamma photons are absorbed by a scintillator material
- C.Gamma photons are reflected by a collimator
- D.Gamma photons are converted into visible light by a lens
Model answer
What a good answer should say
- Photomultiplier tubes convert gamma photons into electrical signals
Explanation
Why this works
Gamma photons are detected by photomultiplier tubes, which convert the light produced by scintillation into electrical signals, allowing for image formation.
