         I've recently hacked together an implementation of
     the Marching Cubes algorithm for "surface-based"
     volume rendering (some would prefer to call it "surface rendering").
     It seems to be working ok with the simple test data that
     I created. The next step is to test it using real volume data.
     There seems to be several popular data sets that appear
     in many volume examples and literature (i.e. the famous MRI
     brain scan of an anonymous woman [I think she has a nickname], 
     the tree sloth, the skulls from the Drebin et. al. and Levoy papers). 

	 Since this data "appears" to be passed around rather freely, 
     I was hoping that someone could tell me where I might find some 
     of these sample data sets for testing my software. Hopefully,
     it is public domain and can be acquired via 'anonymous FTP".
     I suspect that NCSA will have some sample data sets with their
     new ISOVIS software. 
	 Any leads or suggestions would be much appreciated.

				       Thanks, in advance.
