During surgery, the CT scanner takes a sufficient number of two-dimensional initial images using a full field of view. Then within 24 hours of casting, the cast article is steam cured for 12 hours under atmospheric pressure, demolded and placed in an auto clave at 100% humidity. An image produced by the virtual microscope is easily read by a viewer, as it represents a scan of a whole slide rather than individual high power fields of view. The compounds and their salts can be employed as ingredients in pharmaceutical compositions, optionally in combination with other antivirals, immunomodulators, antibiotics or vaccines.
