03/01/13 to inclusion of more soft-tissue or air 80-200 HU (brain) & 40 HU (prostate) Overlap (DSC or MASD) in bone • Dice similarity coefficient or Mean Hausendorf Distance 0.5 < DSC > 0.95 Gamma index • Displayed as a map; combined distance to agreement and dose difference 2% & 2mm > 98% *Typical values observed. Dose difference • Percentage difference at prescription points, isocentre or DVH points 0.3-2.5% MAE • Voxel-wise mean difference in HU; Values sensitive
