||3D interactive segmentation tool "IRIS" developed at the Computer Science
Department UNC. 3D structures are segmented by drawing regions slice by
slice in arbitrary slice directions. The segmented regions are simultaneously
displayed in all the three orthogonal cuts. The 4th window lower left displays
the segmented object as a 3D graphical rendering. Full 3D navigation is
possible by linked cursors in the three orthogonal cuts and the 3D window.
Points and lines can be painted on the object surface by a newly developed
3D painting option. These marked points are simultaneously labeled in the
data volume. This interactive segmentation tool is platform independent
and runs on UNIX and PC computers. The image illustrates the segmention
of left and right hippompal structures.
