Performance evaluation for Biograph 16HR PET/CT

To evaluate the performance specification of Biograph 16HR PET/CT through the acceptance tests.The performance measurement of PET was based on the standard of NEMA standard(2001 version).Using the NEMA standard phantom and methods to test the PET specifications of spatial resolution,scatter fraction,counts losses,random and sensitivity.And also,the stability and global performance were added for evaluate the stability of system and the image quality.The measurement results met the requirement of manufacture's standards,therefore acceptance test was approved.The performance measurements of CT was based on the standard of China CDC CT Acceptance Test Program,report the results including CT value,CT uniformity,CT high contrast spatial resolution,CT low contrast spatial resolution.Imaging fusion alignment was measured as a parameter for combination of PET and CT images.The measured parameters of the PET/CT acceptance test in Siemens Biograph 16HR PET/CT met the requirement of the manufacture's specification.
