You may want to start with the example:
in the directory:
This example is described in detail in the
ITK Software Guide
in the "Image Registration" chapter.
We *STRONGLY* recommend you to read the entire chapter
before you start playing with the registration. You
should also read the Section on image resampling since
they are very closely related.
Since your images seems to be from the same modality
and same patient, you can probably solve this by using
the following components:
1) Mean Squares Metric
2) VersorRigid3D Transform
3) Linear Interpolator
Note that, since you are reading this from DICOM,
you want to replace the "itk::Image" type in the
code with "itk::OrientedImage" type, in order to
make sure that the direction cosines of your images
are taken into account.
Examples on how to read DICOM series are available
in the directory:
and are described as well in the ITK Software Guide
in the Chapter "Reading and Writing Images".
Please let us know if you find any problems
while setting up your registration code.
