GB/T20013《核医学仪器例行试验》分为四个部分:

—第1部分:辐射计数系统;

—第2部分:闪烁照相机和单光子发射计算机断层成像装置;

—第3部分:正电子发射断层成像装置;

—第4部分:同位素校准器。

本部分为GB/T20013的第1部分(以下简称本部分)，等同采用IEC61948-1:2001,

为便于使用，本部分做了下列编辑性修改:

—删去IEC61675-1:1998的前言;

—在第2章“规范性引用文件”中，按GB/T1.1-200。的要求增加了导语;引用的IEC60788:

1984改为引用GB/T17857-1999((医用放射学术语(放射治疗、核医学和辐射剂量学设备)》，

这是因为GB/T17857虽不是等同采用IEC60788，但GB/T17857包含了本部分引用的

IEC60788的有关术语(见附录A);

—在第3章“术语和定义”中，术语的英文不用小的大写字母，而用小写字母;

—用小数点符号.‘’代替作为小数点的逗号‘，’。

本部分的附录A是资料性附录。

本部分由全国医用电器设备标准化技术委员会的放射治疗、核医学和放射剂量学设
