      In Figure 1 we present CT- and MR-derived volumes. The data was taken from radiology.uiowa.edu and www.volren.org.

      a) CT of the human skull;
      b) CT of the human skull with filtration resulting in skin showing;
      с) Sagittal MR image of the brain;
      d) CT of the foot.


a)                                                 b)

voxel size in mm - 0.35x0.35x2, resolution - 256x256x97


c)                                                  d)

voxel size in mm - 0.98x0.98x3 voxel size in mm - 1.00x1.00x1.00
resolution - 256x256x19 resolution - 256x256x256
