Figure 2.

Comparisons of various contour accuracy metrics (DSC vs MDA, DSC vs sDSC, and DSC vs APL) for the A, small bowel, B, large bowel, C, combined bowels, D, pancreas, E, duodenum, and F, stomach before and after the ACR process. Note that the axes of the DSC and sDSC were reversed so contours with higher quality would shift toward the origin for all plots. Abbreviations: ACR = automatic contour refinement; APL = added path length; DSC = Dice similarity coefficient; MDA = mean distance to agreement; sDSC = surface Dice similarity coefficient.
