Figure 2.

Flowchart showing the three steps in the histological analysis of Ki‐67 stained histological sections, which was used for identification of proliferating tumor regions. In the images shown in the first step, individual cells can be seen. Applying the color threshold identifies proliferating cells. The image in the second step is an index map of the entire tumor. The top image in the last step shows a thresholded index map where regions defined as proliferating are shown in green
