“…Spatial Resolution. NEMA NU 2-2012 specifies using a 18 F-FDG point source smaller than 1 • 1 • 1 mm. However, for measuring the spatial resolution on the Vision with smaller crystals, a smaller point source could improve test results (14).…”

“…Timing Resolution. The TOF resolution was calculated using the acquired scatter data used for NECR performance, according to a new proposed method (11,18). The timing resolution was calculated as the FWHM of the time distribution of events, after correction for scatter, randoms, and the position of the line source.…”

“…Therefore, the vendor's NEMA evaluation tools implemented in the Vereos PET/CT system had to be used. Further, the PET raw data would enable additional evaluations, such as assessment of the dependency of the timing resolution on the count rate from the performance measurements (34). Thus, we recommend the implementation of a raw data export function in the standard software.…”

“…TOF resolution was determined for increasing count rates with the FWHM of the timing error histogram computed from the listmode data. This method is based on the work of Wang et al [51] and was recently added to the NEMA NU 2-2018 [6]. There are two main differences compared to the daily quality control procedure, which uses a point source of 22 Na.…”
