NEMA NU 4-2008 标准提出了一种用于评估专为小动物成像设计的正电子发射断层扫描仪 (PET) 性能的标准化方法。
使用 µPET 系统进行散射分数、计数损失和随机重合测量的模型是根据 NEMA NU4-2008(第 4 节)规范设计的。
QRM-MicroPET-Scatter模体由高密度聚乙烯制成。提供三种不同类型的模体,分别代表小鼠、大鼠或猴子的大小。
小鼠模体:
直径:25mm
长度:70mm
线源孔:3.2mm, 偏离中心10 mm
大鼠模体:
直径:50mm
长度:150mm
线源孔:3.2mm, 偏离中心 17.5 毫米
猴子模体:
直径:100mm
长度:400mm
线源孔:3.2mm, 偏离中心 30 毫米
The NEMA NU 4-2008 standard proposes a standardized methodology for evaluating the performance of positron emission tomographs (PET) designed for small animal imaging.
The phantoms for scatter fraction, count losses and random coincidence measurements with µPET systems are designed according to the NEMA NU4-2008 (section 4) specifications.
The phantoms are made from High density Polyethylene. Three different types of phantoms are available, that represent a mouse, rat or monkey size.
