Answer

Answer: Gamma camera / scintillation detector

In nuclear medicine, gamma photons are detected using a gamma camera, whose detector system commonly uses a scintillation crystal such as NaI(Tl) coupled to photodetectors. The detector converts gamma-ray energy into electrical signals for image formation.

The OCR of the paper has lost some answer choices, but CT and MRI do not directly detect gamma rays.
