Validation of sCT

A number of performance metrics are used: Dose difference • Percentage difference at prescription points, isocentre or DVH points

MAE • Voxel-wise mean difference in HU; Values sensitive to inclusion of more soft-tissue or air

Overlap (DSC or MASD) in bone • Dice similarity coefficient or Mean Hausendorf Distance

Gamma index • Displayed as a map; combined distance to agreement and dose difference
