CT Lung Visualisation [message #11542]

I was wondering if someone advise me on the following.
I am trying to create a 3-D visualisation of the lungs from CT data
within IDL. To do this I use the Shade_volume and polyshade commands.
The problem I have is that the voxels are anisotropic, and so
the visualisation looks squashed on storing the slices in an array
of size (512,512,26)
The dimensions are as follows.
x=512,y=512,z=26, xres = 0.5mm, yres=0.5mm, zres=10mm.
(NB the ct slices are contiguous)
Could someone suggest the best way to manipulate the data so
that the visualisation has the correct proportions in all directions

Cheers
Fraser
