How gamma camera works
Web28 aug. 2024 · If all three gamma rays, the original with its energy reduced by 1.022 MeV and the two annihilation gamma rays, are detected simultaneously, then a full energy peak is observed. If one of the annihilation gamma rays is not absorbed by the detector, then a peak that is equal to the full energy less 0.511 MeV is observed. 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.
