I have used the data from the link "MultiChannel Multiple Sclerosis (MS) Phantom Data" in the data link of the vtk homepage. In the ReadMe of this data there is a voxel dimension inusual (0,078 CM, 0,078 CM, 0,03 CM) For me the third dimension is too small. In the MRI a 0,3 MM interslice space is impossible. The Number is wrong????
