The new GE Discovery STE 64-slice CT with PET. The PET scanner has a new BGO detector block of 8 x 6 matrix (6.3 x 4.7 x 30 mm(3)). The aim of this study was to test the performance of the new scanner.
The PET performance evaluation was done using NEMA methodology. Owing to improved front-end electronics, the system was tested with different energy window and coincidence timing settings.
