[vtkusers] insert 2D image into 3D Volume

[Shekhar.Chandra at csiro.au]

Hi Andre,

It's simple in ITK, a sister project to VTK well suited to medical imaging:
PasteImageFilter class is what u want in ITK. You can find more ITK slice (2D to 3D) stuff on my blog at 
< http://l3mmings.blogspot.com/2010/08/slices-stacks-and-itk.html >

In VTK:
Perhaps try vtkSelectArraySlices, vtkArrayExtentsList, vtkExtractSelectedSlices or vtkImageReslice.

Best of luck,
Cheers
Shakes

Hi,

I would like to insert a 2D image (which I extracted before) into a 3D 
Image Volume of medical data.

The 3D Volume has the dimensions  256 x 256 x 20 and I would like to 
replace slice 15 (in z-direction)  by a 2D slice  of same x-y dimensions 
256 x 256 x 1. z-position which I got from a different source.

Since I did't find any clue, how to do that I would be glad if anyone 
can give me a hint...

E.g. is there a filter which does something like that ?

Thanks

Andre
