| Description | Here's a general introduction to many different aspects of antimatter: what it is, where it is made, and how it's already a part of our lives. This is a good overview article with more in-depth information about antimatter. It's from Scientific American. Here's a link to more information about all the antimatter research at CERN. The TED-Ed blog outlines the collaboration with CERN. Michael Doser gives a talk at TEDxGeneva called The Return of Antimatter. Positron emission tomography (PET) is a nuclearmedical imaging technique that produces a three-dimensional image or picture of functional processes in the body. The system detects pairs ofgamma rays emitted indirectly by a positron-emitting radionuclide (tracer), which is introduced into the body on a biologically active molecule. Three-dimensional images of tracer concentration within the body are then constructed by computer analysis. In modern scanners, three dimensional imaging is often accomplished with the aid of a CT X-ray scan performed on the patient during the same session, in the same machine. |
