The new GE Discovery STE and Discovery VCT respectively combine 16-slice and 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.
GE Healthcare is proud to announce that the Discovery* PET/CT 610 has achieved an absolute sensitivity of 10.0 cps/kBq, the highest level found on any scanner on the market.1 Sensitivity is one of GE’s critical foundations of PET/CT imaging, and this double-digit measurement represents a critical milestone. It means the system is designed to deliver fast and detailed scans at low dose.
