Figure 11.6: Depiction of the atlas selection strategies discussed in this chapter.
The strategies are also categorized in Table 11.2. Note that the basic atlas-based
segmentation with a single atlas (IND,
gray box
) occurs in different stages in
the other three strategies, in the MUL case replicated for each atlas.
A schematic graphical comparison of the four methods is given in Fig. 11.6, and
a textual summary of the categorization can be found in Table 11.2.
For each strategy, the resulting segmentation accuracy was evaluated. Auto-
matic segmentations were compared to a manual gold standard segmentation. A
detailed description of the methods used for validation and accuracy evaluation,
