How do gamma cameras work
WebGamma rays are a form of light that moves at a different wavelength than visible light. The cameras are mounted on a rotating gantry that allows the detectors to be moved in a tight circle around a patient who is lying … WebGamma cameras are based on the detection of gamma rays emitted from radionuclides. Radionuclides can be ingested or injected into the body. The camera accumulates counts …

WebGamma camera Radioactive decay Gamma rays are produced by unstable nuclei when protons and neutrons re-range to a more stable configuration. Gamma decay usually follows an alpha or beta decay and does not change element. CLICK: beta decay of molybdenum-99 to technetium-99m followed by gamma decay to technetium-99. Unlike alpha and beta ...
