We present a setup of a simplified positron emission tomograph (PET) which can be used in a third-year laboratory course for physics students. The equipment of a standard γ–γ angular correlation experiment was modified using bismuth-germanate crystals instead of NaI. Using this setup it is possible to locate several radioactive sources hidden in a closed box. The problems of two-dimensional imaging tomography using one-dimensional projections are illustrated as well as the problems encountered in medical PET examinations.
