[Insight-users] any 3D nonrigid registration method in ITK?

[Luis Ibanez]

Hi Changhua,


ITK provides multiple algorithms for computing
Deformable Registration.

The Demons implementation in ITK is N-Dimensional !

There is nothing in the ITK Demons implementation that will
limit it to 2D. You can use ITK Demons in 3D, 4D, 5D...
the only limit is the memory of your computer and the
amount of time that you are willing to let the registration
running.



We have been using Demons for 3D for registering 3D
CT lung datasets, for tracking respiratory movement.


The algorithms in ITK that you can use for
Deformable Registration are:


    1) FEM
    2) BSplines
    3) Demons
    4) LevelSet registration



You will find examples for all of them in the new
edition of the ITK Software Guide


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


The source code of the examples is available in the
directory:

       Insight/Examples/Registration



Regards,


     Luis
