Methods for Estimating Random Coincidences
| Method | Comments |
|---|---|
| Delayed coincidences | Accurate. Higher noise (Eq. 1). Lowest processing requirements. |
| Smoothed delayed coincidences | Accurate. Lower noise (0 ≤ k ≪ 1, Eq. 1). Higher processing requirements. |
| Calculated from single photon rates | Potential for bias if scanner is not properly calibrated. Lower noise (0 ≤ k ≪ 1, Eq. 1). Low processing requirements. |
