1. An imaging system comprising:

  • positron emission tomography (PET) detectors (30) substantially encircling an examination region;

    electronics operatively coupled with the PET detectors to perform coincidence detection of probative radiation comprising 511 keV gamma rays generated by electron-positron annihilation events occurring in the examination region; and

    radiation shielding disposed adjacent the PET detectors to reduce interaction of non-probative radiation with the PET detectors, at least a portion of the radiation shielding comprising an electrically non-conductive and non-ferromagnetic heavy atom oxide material.
