Description
To take advantages of positron emission tomography (PET) in studies of physiological functions of plants, a γ-ray imaging system composed of two block detectors facing each other is under developing. The block detector consists of 10 x 10 lutetium oxy-orthosilicate (LSO) crystals and a position sensitive photomultiplier tube (PSPMT), Hamamatsu R5900-C12, where the element size of the LSO is 1.8 mm x 1.8 mm x 10 mm. The performance of LSO detector was evaluated in terms of applicability to PET. All the detector elements are clearly visualized in the position map. Energy resolution ranges from 14.5% to 22% FWHM at 511 keV. Coincidence timing resolution is improved as the supply voltage of the PSPMT is increased. These measurement indicate that the LSO detector is applicable for high resolution dual block detector imaging system
