Table 2 The calculation steps of combined uncertainty of XLTS.
\({U}_{S}\) | \({U}_{D}\) | \({U}_{C}\) | \({U}_{P}\) | \({U}_{T}\) | |
|---|---|---|---|---|---|
Uncertainty estimated type B | Segmentation uncertainty | Deformation uncertainty | Correlation uncertainty | Prediction uncertainty | Targeting uncertainty |
Standard uncertainty (assuming normal pdf) | SU Segmenation = U S /2 | SU Deformation = U D /2 | SU Correlation = U C /2 | SU Prediction = U P /2 | SU Targeting = U T /2 |
Combined standard uncertainty | \(S{U}_{Combined}=\sqrt{S{U}_{Segmentation}^{2}+S{U}_{Deformation}^{2}+S{U}_{Correlation}^{2}+S{U}_{Prediction}^{2}+S{U}_{Targeting}^{2}}\) | ||||
Expanded uncertainty (k = 2, assuming normal pdf) | \({U}_{Combined}=2\cdot S{U}_{Combined}=\sqrt{{U}_{S}^{2}+{U}_{D}^{2}+{U}_{C}^{2}+{U}_{P}^{2}+{U}_{T}^{2}}\) | ||||
