Web14 feb. 2024 · When a gamma-ray strikes the crystal, photons of visible light are produced at a rate proportional to the energy of the gamma-ray. The light produced is detected by the photomultiplier tubes that sit behind the crystal, which convert it to an electrical signal. Sodium iodide (NaI) is the most common crystal used in gamma cameras. WebIn a scintillation camera the x,y coordinate of each gamma ray interaction in the detector is determined and a spot of light is electronically generated in a corresponding position on the face of a display device (CRT). Each such spot contributes to the latent image on photographic film.
