Figure 1 Spatial distributions of dose deviation between Raystation and Monaco as well as the corresponding DVHs for the 4 individual patients

Figure 2 Deviations between the TPS calculated doses (Raystation vs Monaco) and the TLD measurements from different IROC phantoms. Abbreviations: R = right; L = left; inf = inferior; sup = superior; TLD = Thermoluminescence dosimetry Conclusion The physical beam modeling and proton dose calculation algorithm were precise and the associated calculation uncertainty was within clinical tolerances.
