Construct 3D surface from 2D segmented Contours

Hy, can someone help me to contruct 3D surface in matlab with help of 2D segmentation contours. I am working with CTA Volume, and I have manually segmented boundary of Aorta(internal Organ) by traversing throught 2d axial slices. Now I want to visualize and calculate the volume of segmented aorta, But I have got only 2D contours. Image attached[reproduced from thesis of Fabian Balsiger], shows my requirement that I am able to perform manual segmentation on consecutive 2D axial slices, but what I am looking is to construct/build 3d surface for volume quantification as shown in bottom row of this figure.

Hi, Have you solved this problem? Could you share your experience how you did it?

Thank you!

This approach in this publication is implemented in SlicerRT, which is open source:

It shouldn't be too difficult to port the C++ code to Matlab, especially if your contours are relatively simple and you don't need to consider the complex cases like branching etc.
