Hello,

currently learning how to work with vtk I experienced a strange problem:
I have a dicom data set consisting of an MRI scan with 512x512x87
voxels. I import the data into vtk with a vtkVolume16Reader. When I
display the volume the volume is shifted by 1/3 to the left and the
clipped voxels show up on the other side. So the volume is correct but
the data is offset and repeated. Looking at the images with IrfanView
doesn't show the effect.
I didn't find anything about it in the mailing list so it would be nice
if anybody could explain to me what happened.

Thanks,

Pascal Bertram
