Light division between two ends of scintillation pixel using two photodetectors and appropriate algorithm for signal processing as a method of DOI information extraction is studied in the present work with 2x2x20 mm3 LSO, 2x2x20 mm3 and 4x4x25 mm3 LuYAP pixels under annihilation gamma-quanta excitation and two PMT readout. Influence of optical ...
	Comparison of LuYAP, LSO and BGO as scintillators for high resolution PET detectors Nuclear Science Symposium Conference Record, 2002 IEEE In Nuclear Science Symposium Conference Record, 2002 IEEE, Vol. 3 (2002), pp. 1640-1642 vol.3. by S.

Halling posted to high lso luyap pet resolution scintillator by rbmoura on 2008-04-02 11:34:11 Abstract Copy My Attachments My Copy Abstract For high resolution positron emission tomographs based on scintillation detectors a fast, dense and bright scintillator is required. An early sample of a new scintillator, Lu/sub 0.8/Y/sub 0.2/AlO/sub 3/:Ce (LuYAP) with a density of 7.7g/cm/sup 3/ and a scintillation decay time of 20 ns and 160 ns is compared with LSO and BGO crystals of the same size to estimate the potential of the crystal for high resolution PET detectors. Special attention was paid to use an application specific measurement setup ...

Teller posted to luyap lyso properties scintillation scintillator by rbmoura on 2008-04-02 11:22:53 Abstract Copy My Attachments My Copy Abstract The Crystal Clear Collaboration has built a small animal PET, the ClearPET/spl trade/ and is now working on a dedicated PET for mammography, the ClearPEM/spl trade/. The /spl gamma/-ray detectors in these machines consist of matrices of small scintillation crystals coupled to photo detectors. In all the detectors for the ClearPEM/spl trade/ about 6000 LYSO (2/spl times/2/spl times/20 mm/sup 3/) crystals are used while for the ClearPET/spl trade/ the number is around 5000 LYSO and the same amount of LuYAP crystals ...

Zaidi posted to luap luyap properties scintillator by rbmoura on 2008-04-01 19:57:59 Abstract Copy My Attachments My Copy Abstract This paper presents the development of new Ce-doped, fast and high effective-Z mixed Lux(RE3+)1-xAP:Ce crystals. These crystals have been grown by the Czochralski method and good results have been obtained with x=0.1, 0.2 and 0.3 for Y3+ ions and roughly between x=0.6 and 0.7 for Gd3+ ions. Relative light yields measured for the Lux(RE3+)1-xAP:Ce crystals are 40-75% higher than for BGO and are comparable to the light yield of YAP:Ce crystal. Measured energy resolutions at 662 keV range over 8-15.3% and ...
	Intrinsic energy resolution and light output of the Lu0.7Y0.3AP:Ce scintillator Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, Vol. 493, No. 3. (11 November 2002), pp. 131-136. by C. Kuntner, E. Auffray, P. Lecoq, C. Pizzolotto, M. Schneegans posted to energy light luyap scintillator yield by rbmoura on 2008-04-01 19:56:02 Abstract Copy My Attachments My Copy Abstract Light output and energy resolution for a 2x2x10 mm3 LuYAP:Ce crystal coupled to a XP2020Q photomultiplier were studied. The measured light output of 8530 photons/MeV includes the correction for the quantum efficiency of the XP2020Q photomultiplier. An energy resolution of 7.33% was obtained for 662 keV [gamma]-rays with a long face coupled to the PMT. The measured number of 2130 phe/MeV implies a photoelectron statistical contribution of 6.59% and hence a LuYAP intrinsic energy resolution of 3.21%. The relative light output ...
