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.
