Segmentation

Image volume must be segmented into its anatomical constituents.
Automatic segmentation is not possible.
Interactive, semiautomatic segmentation is time consuming (one man-year to segment 300 anatomical objects).
Algoritms ( histogramming, thresholding, edge enhancements, non-rational uniform B-spline).
Map Seperation methon in AVS (demo) (mussle easy, bone difficult).
Map separation implementation in Java (demo).
Bone tissue cannot be separated from anatomical images.
We must come back to CT images and do aligning CT-anathomy.
