Abstract:
Post installation acceptance testing is vital to demonstrate that the equipment meets the vendor's specification and is suitable for clinical studies. The test procedures described in the NEMA NU 2-2001 document form the basis of vendor performance specifications of PET scanners and hence are also appropriate for acceptance testing. Initial installation performance tests of the Philips Gemini GXL PET/CT scanner installed at Liverpool Hospital revealed that the peak noise equivalent count rate (NECR) measurement of 57.5 kcps was substantially lower than the specification of 70 kcps and the scatter fraction of 38.5% was 10% higher than the specification of
