[Insight-users] Convert a set of 2D images to 3D

[Luis Ibanez]

Hi Luis,

You should instantiate the Paste filter in 3D.

Since you are going to paste 2D slices into a 3D image,
you need to set up the filter in such a way that a 2D
image is seen as a 3D image of a single slice.


    Regards,


        Luis
