3-d reconstruction of sequence of 2-d images

I have a sequence of 2-d circlular cross-sectional images of blood vessel. I would like to know how can I connect them to each other to get a 3-d reconstructed image for the blood vessel, and be able to go through it and view it from inside. Is there some thing in Opengl that can help me with that?
Thank you.

This link was on www.opengl.org recently. Maybe you can apply that to your data. http://www9.informatik.uni-erlangen.de/~cfrezksa/VolRen/

Not a particularly simple thing to do. Do a search on ‘computer vision’, thats the subject area for such things. I will send you some links later
