【NEMA PET散射模体】
NEMA PET Scatter Phantom Set
型号/Model：PET/NEMA-SCT/P
NEMA PET散射模体 PET/NEMA-SCT/P型
NEMA PET散射模体主要特点:
-NEMA PET散射模体依据美国电气制造商协会(NEMA)标准设计生产，用于散射存在时对闪烁体相机的计数率表现进行标准化测量
The NEMA Scatter Phantom is designed in accordance with the recommendations by the National Electrical manufacturers Association (NEMA) to standardize the measurement of count rate performance of a scintillation camera in the presence of scatter*
-模体为实心正圆高密度聚乙烯柱状体
Is a solid right circular high density polyethylene cylinder
-模体具有一个可填充式线光源支撑架，其位置与柱状体中心轴平行，偏心距为4.5 cm
Has a fillable line source holder parallel to the center axis of the cylinder and offset a distance O.D. 4.5 cm
-圆柱模体由四部分组成，易于携带及存储
The cylinder is made of four sections for ease of carrying/storage
