How a gamma camera works
Web10 de out. de 2024 · A gamma photon that scatters within the patient will never hit the scintillator with the full energy (i.e. it won’t lie within the peak). Therefore, only gamma photons in the peak can be confidently identified as non-scattered radiation from the patient. Usually a 20% acceptance window is used centred on the photopeak.

WebGamma correction is sometimes specified in terms of the encoding gamma that it aims to compensate for — not the actual gamma that is applied. For example, the actual gamma applied with a "gamma correction of 1.5" is often equal to 1/1.5, since a gamma of 1/1.5 cancels a gamma of 1.5 (1.5 * 1/1.5 = 1.0). A higher gamma correction value might ... WebA Gamma Camera is a device, which is used as an imaging technique to produce functional scans of the brain, lungs, thyroid, liver, skeleton, gallbladder and kidneys. This technique is known as Scintigraphy. Large crystal of sodium iodide is used to detect the gamma photons. Whenever gamma photon hits the crystal, it gives a tiny flash of ...
