A new scintillation crystal, cerium-doped lutetium oxyorthosilicate (LSO), was recently discovered, with light intensity 75% of NaI(Tl), scintillation decay time of 12 ns (30%) and 42 ns (70%), effective Z of 66, and density of 7.4 g/cc. The fast decay time and scintillation light output of LSO are superior to those of bismuth germanate (BGO) for positron emission tomography (PET) and the stopping power of LSO for 511 keV photons is only slightly lower than that of BGO. The authors directly…

Development and Improvement of Cerium Activated Gadolinium Gallium Aluminum Garnets Scintillators for Radiation Detectors by Codoping

Polycrystalline Gd3Ga3Al2O12:Ce (GGAG:Ce) pellets with various codopants were prepared via solidstate synthesis and characterized by X-ray diffraction, radioluminescence (RL), photoluminescence (PL),

Gamma ray spectroscopy and timing using LSO and PIN photodiodes

The high density, high light output, and short decay time of LSO (lutetium orthosilicate, Lu/sub 2/SiO/sub 5/:Ce) make it an attractive scintillator for gamma ray spectroscopy. The low cost, small

Design considerations of an animal PET scanner utilizing ESO scintillators and position sensitive PMTs

Various parameters relevant to the design of a small scale PET scanner were studied both experimentally and by computer simulation. LSO (cerium-doped lutetium oxyorthosilicate) was compared with EGO,

Evaluation of Geiger-mode APDs for PET block detector designs

An evaluation of two types of Geiger-mode avalanche photodiodes for their potential to be used in a positron emission tomography (PET) detector finds G-APDs with a low number of cells provide a good timing and linear signals in block detector designs, where the scintillation light is shared over many G- APDs.

Performance characteristics of a compact position-sensitive LSO detector module

The results suggest that this scintillator/phototube combination should be highly effective in the coincidence mode and can be used, with some limitations, to image relatively low-energy single photon emitters.
