Noise components on PET images were studied. The results showed that the square of synthetic noise Δ2 and the square of signal-to-noise ratio (N/Δ)2 varied with the signal intensity N and the relationships were respectively expressed with: Δ2 = 0.0395N2 + 0.1427N + 0.0025 (R2 = 0.9358) and (N/Δ)2 = −1.13932N2 + 7.0185N − 0.0746 (R2 = 0.9377). The synthetic noise on PET image may be categorized into three components. The first one varies directly as signal intensity, which depend on random coincidence; the second one varies directly as the square root of signal intensity, which depend on Poisson fluctuation; and the third one is independent of signal intensity. |
