Hello Everyone!!

I have biplane cerebral angiograms. I have got the two aneurysm view aligned in 3D and have formed a volume consisting of elliptical cross sections. Now I need to get a smooth surface from those elliptical cross sections stacked together.
Can someone help me out?
Do we have some command in Matlab that will do this stuff?

Thank You,

Regards,
Gaurav

Form volume data use the "isosurface" command.

otherwise this one should work:

Hi,

I just wanted to point out that MATLAB isosurface function has a lot of problems for complex data.

I have created a program that renders exact (without smoothing) error-free surfaces from 3-D voxel data, such as from MRI, CT Scan.

The following is the link to the discussion thread

http://www.mathworks.com/matlabcentral/newsreader/view_thread/268226#755017

You can download the program from
