Well it is not really clear what you want.  CT scanners used now for more 
than 15 years in medical diagnosis work by generating 3D images from 
projections.  I assume you know this: the text books are in the library.

If you are looking for canned programs which will do CT-type reconstructions 
from projections I am sure they are available from many places.  We have 
written programs for image processing which do reconstructions from projections 
(amongst many other things).  These are available from the DECUS library: 
submission V00535 for VAX/VMS or Ultrix.  The package is called MDPP.
