How do gamma cameras work
WebMay 16, 2024 · The Anger scintillation gamma camera, which currently dominates single-photon x- and γ -ray nuclear imaging, is an example of the latter method. The scanning detector system is less expensive, but the position-sensitive detector system permits more rapid image acquisition and has replaced single scanning detector systems. WebThe gamma camera records the energy emissions from the radiotracer in your body and converts it into an image. The gamma camera itself does not emit any radiation. It has radiation detectors called gamma camera heads. These are encased in metal and plastic, often shaped like a box, and attached to a round, donut-shaped gantry.

WebHow do Gamma Scintillation Cameras work? The emitted photons are first discretised by direction using a collimator. The collimator ensures that each small part of the crystal views only a small area of the organ to be imaged. Each interactions of a gamma ray with the detector crystal is called an ‘event’. Scintillation imaging produces WebA special camera detects gamma ray emissions from the radiotracer. The camera and a computer produce pictures and supply molecular information. Many imaging centers combine nuclear medicine images with computed tomography (CT) or magnetic resonance imaging (MRI) to produce special views. Doctors call this image fusion or co-registration.
