Dose distribution differences between the mass conserving and original XCAT phantoms for the 54 Gy SBRT treatment (a) and the 66 Gy conventional treatment (b) with regular breathing. The dose difference, ΔDose, is defined as the dose calculated in the original XCAT phantom minus the dose calculated using the mass conserving phantom. The coronal and sagittal slices are chosen to go through the center of the target lesion. A positive value of ΔDose corresponds to regions where a dose calculation using the original XCAT would overestimate the dose, and regions with a negative ΔDose value are where the original XCAT would underestimate the delivered dose relative to the mass-conserving phantom. Regions with dose differences smaller than 0.1 Gy in magnitude are not shaded.
