Table 4 Results of the regression analysis between the recovery coefficient (RC) and surface area-to-volume (SA:V) ratio for the infinity, 10-to-1, 5-to-1, and pooled target-to-background ratios of all kidney phantoms in the study
From: The magnitude of the partial volume effect in SPECT imaging of the kidneys: a phantom study
Infinity TBR | 10:1 TBR | 5:1 TBR | Pooled | |
|---|---|---|---|---|
Equation of best fit | RC [%] = 99.8 − 16.1 * SA:V [cm−1] | RC [%] = 99.8 − 16.1 * SA:V [cm−1] | RC [%] = 103.0 − 15.6 * SA:V [cm−1] | RC [%] = 100.9 − 16.0 * SA:V [cm−1] |
