Abstract:
Objective To probe into the application quality and performance test of PET/CT.Methods Radionuclide 18F was used to detect PET including its spatial resolution,sensitivity,scatter fraction,count losses and image quality.American Catphan-424,ionization chamber of Sweden Barracuda and radial measuring apparatus were used to perform CT test including CTDI,scan localization light accuracy,slice width,spatial resolution,density resolution,field uniformity and noise,CT value linearity and contrast scale,table movement accuracy.Results PET/CT was qualified as the whole,but part of parameters were beyond the limits.Conclusion The performance test can efficiently ensure the quality and safety of PET/CT system.
