The historical focus of TRIUMF’s research has been in accelerator-based subatomic physics and the related accelerator, detector, and isotope-production technology. Not only can critical isotopes used for medical imaging and treatment be produced with TRIUMF’s accelerators (called cyclotrons), but the techniques used by subatomic physicists to peer “inside” the atom can be used to image and trace these agents inside the body to study human health and disease in research known as nuclear medicine.


The core of the TRIUMF nuclear medicine program is positron-emission tomography (PET) imaging, a technique whereby tiny amounts of radioactive nuclei known a
