Hi Marta,

If you want to get a surface that defines the boundary of
an anatomical structure (e.g. kidneys, liver, bones...)
contained in a medical image, you should perform the ritual
of "image segmentation".

There are many methods of image segmentation, and new more
are proposed every day. The reason is that every combination
of image modality, anatomical structure and clinical application
have very specific requirements and constraints. It is impossible
for a single segmentation method to be applicable to all the
variations of medical image needs.

You will find a description of the most commonly used segmentation
method in ITK into the ITK Software Guide


      http://www.itk.org/ItkSoftwareGuide.pdf


as well as in the Segmentation Tutorial:

http://www.itk.org/CourseWare/Training/SegmentationMethodsOverview.pdf

 From the set of Tutorials at:

      http://www.itk.org/HTML/Tutorials.htm


Once you have segmented the anatomical structure of your interest,
it is possible to extract a surface around it, and use it for the
purpose of registration.



Please let us know if you have further questions,



     Thanks,


       Luis
