PET模块，包括一对紧凑的，高分辨率和大面积的探测器的基础上硅光电倍增管（SiPM）的开发和评估。探测器的有效面积为24 mm x 24 mm，采用1.9 mm x 1.9 mm x 10 mm的LYSO晶体和电荷分配电路，以获得相对简洁的前端电子学（FEE）的高空间分辨率。初步结果表明，探测器与1.5 T磁场兼容。系统的本征半高宽空间分辨率为1.50 mm，平均能量分辨率为18.5%，符合时间分辨率为2.6 ns。(C)2011爱思唯尔有限公司版权所有。
A PET module that comprises a pair of compact, high-resolution and large-area detectors based on silicon photomultipliers (SiPM) was developed and evaluated. The detector's effective area was 24 mm x 24 mm. LYSO crystals measuring 1.9 mm x 1.9 mm x 10 mm and charge division circuit were employed to obtain high spatial resolution with relatively concise Front-end electronics (FEE). Initial results showed the detector to be compatible with 1.5 T magnetic fields. The system's intrinsic FWHM spatial resolution is 1.50 mm. The average energy resolution is 18.5% and the coincidence timing resolution is 2.6 ns. (C) 2011 Elsevier B.V. All rights reserved.
