DSC between segmentations of the unaltered first scan, the defaced first scan, and aligned rescan on the Kirby-21 dataset. In each column, we present the results for the segmentation comparison between the unaltered first scan and either a defaced first scan or the unaltered rescan aligned to the first scan. The raindcloud plots are explained in Fig. 2. Key: “$\text{rescan}+\text{rigid}$”—rescan registered with rigid registration; “$\text{rescan}+\text{affine}$”—rescan registered with affine registration; “$\text{rescan}+\mathrm{syn}$”—rescan registered with SyN based deformable registration.
