Marcio,
You'll have to scan them with a transparency scanner
into BMP files (or other format for which there exists a
Reader in vtk), at a high enough resolution to capture
the relevant information (e.g., the Visible Human CT
images of the frozen male's lower extremities, in GE
Signa format, are 512x512 pixels, with a pixel spacing
of 0.9375mm in X & Y, with each pixel taking on a 12-bit
intensity value).

Then you'll have to align the images with one another in
X & Y, and add an origin & the pixel spacing info to the
vtkImageData read in by the vtkBMPReader (or whichever
reader you end up using).

HTH,
