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 … WebThe gamma camera is a machine that allows two-dimensional imaging of physical processes within the body using a radiopharmaceutical. A radiopharmaceutical is a drug …
WebSince the two gamma rays produced are emitted in opposite directions, the camera heads must be moved so that they are always opposite one another. Another difference is that … 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.
