Since Cyclotron and Radioisotope Center was established in 1977 for multi-purpose use of cyclotron at Tohoku University, the cyclotron has been used mainly for the studies of nuclear physics and nuclear medicine using Positron Emission Tomography (PET). The PET study has been much developed at Tohoku University by the collaboration of medical scientists with physicists. The contribution of physicists to the development is briefly presented here.
