Table 2:

Median Dice Similarity Coefficients of automated segmentations generated using different combinations of image similarity and atlas fusion methods against expert segmentation for all OARs of the internal INST dataset. DSC for the preferred combination, CT-radiodensity and SWV, are presented in bold. Values marked in ** and * were found to be statistically significant when compared against CT-radiodensity and SWV, with p-value < 0.001 and p-value < 0.05, respectively. SMG = Submandibular Gland.
