This sounds like something I tried to do about a month ago. Except
mine were 512x512x12bit CT scan images. Of course the relative intensities
sould have been 0 to 4095 so the code looked like this:

a=intarr(512,512)
a=ishft(a,-4)
tvscl, a

This could create an image, but for some reason there was alot of
noise around where the bone should have been. I have tried many different
scaleing procedures that haven't helped. I also noticed that the data is
chopped because the upper value is 4080. This would probably be the cause
of the upper end noise since dence bone should be above 4080. I had to do
the shift because of IDL being 16 bit.
