Abstract:
Objective:It is to discuss results and significance of PET/CT in the performance tests.Methods: According to NEMA NU 2-2007 Performance Measurements of Positron Emission Tomographs and GB 17589-2011 specifications for quality assurance test for computed tomography X-ray scanners standards, with phantoms of nuclear medicine and CT, performance testing was done.Results: Spatial Resolution (FWHM): transverse 1 cm 4.16 mm, axial: 1 cm 4.04 mm, transverse 10 cm 4.92 mm, axial: 10 cm 5.74 mm. Sensitivity: 9.6 s-1·kBq-1, scatter fraction: 35.4%, peak NEC rate: 1.69×105 s-1.Conclusion: According to manufacturers and national standards, the results of performances testing are up to standard. It is necessary to enhance the effect of in quality control(QC) of PET/CT and the fundamentality of the performance tests, so that the devices come to the demands for clinical practice.
