I messed around with it a little more and was able to extract raw binary 
from the tiffs with GraphicsMagick's convert:

     $ convert nir_tomo.tif nir_tomo.gray

I then verified that the file size was correct:

     $ ls -l nir_tomo.gray
     -rw-rw-r-- 1 hal hal 22048706 Aug 10 07:57 nir_tomo.gray
     $ echo $(( 239 * 239 * 386 ))
     22048706

Then I opened it in ParaView as a raw binary file.  I specified the 
extent as [0,238,0,238,0,385], since the dimensions of the image were 
[239,239,386].
