How do gamma cameras work
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 ... WebJul 3, 2024 · The collimator of a Gamma camera used in nuclear medicine differs in structure and function to the beam collimators used in general radiography.. They typically consist of a lead disc drilled with tens of thousands of closely packed holes, separated from each other by septa. Each hole only accepts Gamma rays to travel through a narrow …
