Abstract
A single-ring positron emission tomograph is based on composite detect ors of the new type comprising stacked thin layers of plastic scintill ator and lead foil. The main characteristics of the tomograph were mea sured including spatial resolution (4-6 mm in the detector plane), sen sitivity (5859 coincidences per 1 mu Ci/ml solution activity), and the number of accidental coincidences and the coincidences due to scatter ed gamma-quanta. A tomographic image of the standard Derenzo phantom w as obtained.
