[Insight-users] Extract an oblique 2D slice from a 3D volume

[Luis Ibanez]

Hi Gheorghe


You may want to use the

             ResampleImageFilter


You will have to provide the Transform that defines the resampling
plane, and the parameters of the image grid that you want to use
for the 2D image.

Please read the ITK Software Guide


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


in particular the section on "Geometric Transformations".

This section describes how you can set the parameters of a
resampling problem.



     Regards,


       Luis
