Figure 10.10
Segmentation method III applied to data set #1 (malignant lesion, tubulo-lobular
carcinoma) with four clusters. The left image shows the cluster distribution for
slices 13 through 16. The right image visualizes the representative time-signal
intensity curves for each cluster. See plate 5 for the color version of this figure.

Figure 10.11
Segmentation method I applied to data set #4. The left image shows the lesion's
extent over slices 6 to 8. The right image shows the average time-signal intensity
curve of all pixels belonging to this lesion.
