IEC TR 61948-3:20 18(E)描述了正电子发射断层扫描仪(PET)的测试方法。作为质量控制的一部分，本文件定义了正电子发射断层扫描仪用户应执行的常规测试，以保持适当的操作条件。将这些常规测试的结果与验收测试期间或之后确定的参考数据进行比较。IEC 61675-1:20 13中描述了用于验收测试的方法。此外，今天正电子发射断层摄影机通常包括用于计算机断层摄影术(CT)的X射线设备。对于本文件，PET/CT混合设备被认为是现有技术，不包括X射线组件的专用正电子发射断层扫描仪仅是特殊情况。IEC 61223-2-6.CT扫描仪还应根据IEC 60601-1以及适用的附属标准和特定标准进行型式测试。第二版取消并取代了2005年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a)增加了检查常规性能测试的条款，b)增加了检查PET和CT图像共配准准确性的测试，c)增加了检查图像质量的测试，d)检查像素大小的测试已被移除。

IEC TR 61948-3:2018(E) describes test methods for Positron Emission Tomographs (PET). As part of quality control, this document is defining routine tests to be performed by the user of Positron Emission Tomographs to maintain proper operation conditions. The results of these routine tests are compared to the reference data determined during or after acceptance test. Methods used for acceptance tests are described in IEC 61675-1:2013.
In addition, today a Positron Emission Tomograph often includes X-Ray equipment for Computed Tomography (CT). For this document, PET/CT hybrid devices are considered to be state of the art, dedicated Positron Emission Tomographs not including the X-ray component being special cases only.
quality control tests specific to only the CT component of the PET/CT are described in IEC 61223-2-6. The CT scanner also is subject to a type test according to IEC 60601-1 and applicable collateral and particular standards.
This second edition cancels and replaces the first edition published in 2005. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) a clause to check routine performance tests has been added,
b) a test to check the accuracy of co-registration of PET and CT images has been added,
c) a test to check image quality has been added,
d) the test to check pixel size has been removed.
