We are looking for info on automatic digitizers capable of digitizing
objects with holes and voids.  These objects typically have volumes
no larger than 200x200x200 mm.  It would be nice to have both an accuracy
and resolution of about 0.5mm.  We really do not care how much time the 
digitizer requires; several hours would be more than acceptable.  We
are concerned however, that the digitizer be able to "probe" into
holes (we understand the mechanics and trigonometry involved and know
how difficult this is).

As a test case, we would like to digitize a human skull with enough
accuracy to capture the sutures, dentition, and orbits.  If you 
know of such a digitizer, we would certainly appreciate hearing from
you.
