Abstract	We have developed 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 block detector rings with the ring diameter of 390 mm and each block detector ring consists of 24 DOI detectors. In this paper, we describe the system and performance evaluation of the jPET-D4. In particular, we evaluate scatter fraction, sensitivity and count-rate performance of the jPET-D4 by using the NEMA NU2-2001 standard. The average scatter fraction for this system is 42 % with an energy window of 400-600 keV. The sensitivity at the center of the field-of-view is 19.5 kcps/MBq with energy window of 400-600 keV. Peak NECRs (noise equivalent count rate; NEC1R and NEC2R) with 10 ns coincidence time window are 82 kcps at 8.7 kBq/ml and 56 kcps at 7.6 kBq/ml, respectively. These evaluation measurements indicate the jPET-D4 has excellent performance.
