The Visible Human Project data sets are designed to serve as a common
reference point for the study of human anatomy, as a set of common pub
lic-domain data for resting medical imaging algorithms, and as a testb
ed and model for the construction of image libraries that can be acces
sed through networks. The data sets are being applied to a wide range
of educational, diagnostic, treatment planning, virtual reality, artis
tic, mathematical, and industrial uses by more than 800 licensees in 2
7 countries. But key issues remain in the development of methods to li
nk such image data to text-based data. Standards do not currently exis
t for such linkages. Basic research is needed in the description and r
epresentation of image-based structures and in the connection of image
-based structural-anatomical data to text-based functional-physiologic
al data. This is the larger, longterm goal of the Visible Human Projec
t: To link the print library of functional-physiological knowledge wit
h the image library of structural-anatomical knowledge transparently i
nto one unified resource of health information.
