| 内容記述 | In building a PET scanner, crystal read-out using wave-length shifter fi bers（WLS）permits the use of many small crystals with a reduced number of photo-sensors, thus promising good spatial resolution at low cost. However, the main drawback of this method has been low efficiency of photon collection. Improvements in design of our readout system over the last several years have resulted in a factor of more than ten in the collection of photons. In the present study, a narrow gamma-ray beam is injected to a matrix detector composed of 16 × 16 LYSO : Ce crystals which are read out by using 2 × 16 Kuraray Y-11 WLS fi bers and two Hamamatsu H6568ModIII photomultipliers. A good spatial（0.34 mm RMS）and time resolution are obtained. The observed time resolution allows the use of 10 ns coincidence time window with a loss of 8.8%. A detection efficiency close to that of a single block LYSO crystal directly mounted on PM was obtained. A sketch of a full size animal PET scanner with 20 cm internal diameter is given. Building such a device by using the method developed in the present study needs only 54 photomultipliers identical to those used in this study. | |||||
