Figure 10.14
Segmentation method III applied to data set #4 (malignant lesion, ductal
carcinoma in situ) and resulting in four clusters. The left image shows the cluster
distribution for slices 6 through 8. The right image visualizes the representative
time-signal intensity time curve for each cluster. See plate 6 for the color version of
this figure.

Figure 10.15
Segmentation method I applied to data set #10 (ductal carcinoma in situ). The left
image shows the lesion's extent over slices 16 to 18. The right image shows the
average time-signal intensity curve of all pixels belonging to this lesion.
