3-D blood vessel tracing

We had a visitor from Harvard Medical School and Massachusetts General Hospital here at MathWorks headquarters in November. Alex Tyrrell is a postdoctoral fellow at the Edwin Steele Laboratory there. Alex gave a presentation in which he showed some fascinating videos, created using MATLAB, of a three-dimensional automatic blood vessel tracing technique using a "superellipsoidal model." Here's the first frame of a sample video that Alex made:

The technique is described in:

Tyrrell, Roysam, di Tomaso, Tong, Brown, and Jain, "Robust 3-D modeling of tumor microvasculature using superellipsoids," 3rd IEEE International Symposium on Biomedical Imaging: Macro to Nano, 2006.

It's fascinating stuff. Thanks, Alex.

    I have a stack of 2D polygons. Can u suggest me a way to stack these polygons in 3D such that I get a 3D object out of these 2D polygons.

    Sridharan—I don’t know anything about that topic. You might find something useful in this MATLAB Central contribution.
