@Poorya, I'm afraid I cannot assist you, because I do not understand the problem sufficiently. Others on this web site know a lot more than me about DICOM images. I think they will be able to assist you. They will be more likely to help if you post with a small example of your problem, with the associated files.

By "3D mesh volume" do you mean "volumetric image"? By "node" do you mean "voxel"? By "element" do you mean the aorta voxels of the image? You will need to "segment" the image to produe a mask where true=aorta and false = non-aorta. I can't say how to do that without seeing the image but you may want to look at published papers:

and you might take a look at imregister
