scope:

NPR-IEC/TR 61948-3 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.
