| 内容記述 | We are developing a high-performance brain PET scanner, jPET-D4. This scanner is designed to achieve not only high spatial resolution but also high sensitivity using four-layered depth-of-interaction (DOI) detectors. The scanner has five detector rings with the ring diameter of 390 mm and each detector ring consists of 24 DOI detectors. In order to identify the crystal of interaction and its energy from PMT output, we have previously proposed the DOI detector calibration method. This method creates position and energy Look-Up-Tables (LUTs) from the uniform irradiation. The position LUT converts location of 2D position histograms to crystal addresses. The energy LUT corrects light output of each crystal. Five detector rings have been installed and calibrated. The average energy resolution for 120 DOI detectors is optimized to 17 %. The scatter fraction for this system is 38 % with energy window of 400-600 keV. The sensitivity for point source is 112 kcps/MBq with a 250 keV LLD. | |||||
