BS PD IEC/TR 61948-3:2018 describes test methods for POSITRON EMISSION TOMOGRAPHS (PET). Aspart of QUALITY CONTROL, this document is defining ROUTINE TESTS to be performed by the userof POSITRON EMISSION TOMOGRAPHS to maintain proper operation conditions. The results ofthese ROUTINE TESTS are compared to the REFERENCE DATA determined during or afterACCEPTANCE 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 forCOMPUTED TOMOGRAPHY (CT). For this document, PET/CT hybrid devices are considered to bestate of the art, dedicated POSITRON EMISSION TOMOGRAPHS not including the X-ray componentbeing special cases only.QUALITY CONTROL tests specific to only the CT component of the PET/CT are described inIEC 61223-2-6. The CT SCANNER also is subject to a TYPE TEST according to IEC 60601-1 andapplicable collateral and particular standards.Cross References:IEC 61223-2-6:2006IEC TR 61948-1:2016IEC 61675-1:2013IEC 60601-1:2005IEC 60601-2-44:2009IEC TR 60788:2004
