Table 1.
Scintillation properties of selected scintillators appropriate for use in TOF PET. The 511 keV linear attenuation coefficients are shown under the μ511 column. We do not include parameters for Calcium and Magnesium co-doped LYSO since there are not enough consistent data available in peer-reviewed publications yet.
