-
- Since this was one in our laboratory (although years before i got here),
- i thought i'd shed a little light.
-
- The purpose behind this was not to digitize the body parts or scan them
- into a computer, but to determine the center of gravity of the body and of
- each of its limbs. Although it has been criticized as morbid and wasteful,
- the data has been used and cited hundreds of times since.
-
- Yes the body was frozen, and each limb was cut into slices about 1" thick
- the slices were measured and weighed, and the center of gravity and density
- of each was determined.
-
- Incidently, the same investigator, Dr. Edmund Chao, has recently begun a
- project which is probably more related to the original post (although i
- missed it). CT scans of a human cadaver were done at 1.5 mm intervals from
- head to toe. This data has not yet been processed into anything useful yet,
- and is currently filling about 1 GB of disk space.
-
- Please don't ask for information, the project is no longer in our lab. It
- is somewhere between John's Hopkins University and Iowa State University.
- It is unlikely that it will be in the public domain for some time if ever.
