Table 2 Measured count rates and scatter fraction for the mCT Flow system (NEMA NU2-2012) and comparison with the published values (NEMA NU2-2007) of the mCT system [6]
Parameter | Measured (mCT Flow) | Published (mCT) [6] |
|---|---|---|
Peak true rate | 634 kcps at 42.4 kBq/ml | – |
Peak NECR | 185 kcps at 29.0 kBq/ml | (180 ± 8) kcps at (28.3 ± 0.6) kBq/ml |
Scatter fraction at low counting rates | 33.5 % at 0.5 kBq/ml | 33.2 ± 0.7 % |
Scatter fraction at Peak NECR | 33.4 % at 29 kBq/ml |
