Abstract:
Objective To test image quality, accuracy of attenuation and scattering corrections of PET with NEMA NU2-2001. Methods By using NEMA IEC/2001 PET Phantom,along with the test methods recommended by NEMA NU2-2001, the PET image quality, accuracy of attenuation and scatter corrections were measured. Results Relative error in attenuation and scatter corrections were 0.25 (n=4) and 0.25 (n=8) respectively. Conclusion It's difficulty to prepare the phantom and process data. Preparing the phantom according to the radioactivity ratio strictly and processing data carefully even with many times, the exact result of the test can be obtained.
