A PET Prototype
This device from the 1960s is an early prototype of a positron emission tomography (PET) scanner. Scientists at the Department of Energy’s Brookhaven National Lab built this circular version of the PET scanner to image small brain tumors and nicknamed it the Head-Shrinker.
PET scans work after radioisotope tracers are introduced into the patient. The imaging equipment picks up gamma rays emitted as a result of the isotope’s decay. The system allows for functional imaging of processes throughout the body. The device is now used for research and to diagnose certain cancers, brain diseases and heart problems.
