Fig. 4From: Three-dimensional morphological changes of the temporomandibular joint and functional effects after mandibulotomy Red arrows represents Hausdorff distance. a Illustrates two overlapped discs with linear relationship between the DSI and the RMSD (i.e. low DSI value due to displaced disc and high RMSD). b Illustrates two perfectly overlapped discs with non-linear relationship between the DSI and the RMSD (i.e. high DSI value due to excellent disc overlap, but high RMSD value)Back to article page
