Ventilation Series Similarity: A Study for Ventilation Calculation Using Deformable Image Registration and 4DCT to Avoid Motion Artifacts

Figure 5

Dice similarity coefficient (DSC) data: (a) the average DSC versus phase for the lower 30%, upper 70%, and 50% ventilation volumes and (b) the average DSC for the 50% ventilation volume between neighboring phases. The solid line curve in (b) is redrawing of the DSC versus phase for the 50% volume as a reference.
