正电子发射粒子跟踪 (PEPT) 是一种通过跟踪放射性标记粒子来研究工程系统内部流动的强大技术。正电子相机用于记录正电子湮灭产生的重合数据;由于 PEPT 的精度取决于记录的数据速率,因此相机灵敏度至关重要。我们报告了新型正电子相机 SuperPEPT 的初步结果,该相机是使用 CTI/西门子 ECAT EXACT 31、ART 和 EXACT HR+ 扫描仪的组件构建的,并具有具有大视场 (FOV) 的多功能几何结构。这些结果仅使用三个探测器部分中的两个获得,但已经显示出灵敏度和数据速率远高于以前的正电子相机所能达到的水平。
Positron emission particle tracking (PEPT) is a powerful technique for studying flow inside engineering systems by tracking radioactively-labelled particles. A positron camera is used to record coincidence data arising from positron annihilation; since the precision of PEPT depends on the recorded data rate, the camera sensitivity is crucial. We report first results from a new positron camera, SuperPEPT, which has been constructed using components from CTI/Siemens ECAT EXACT 31, ART, and EXACT HR+ scanners and has a versatile geometry with a large field-of-view (FOV). These results were obtained using just two of the three detector sections but already show sensitivity and data rates much higher than achievable with previous positron cameras.
