Using high resolution slices of a female cadaver, scientists have created the world’s most digital detailed body, one that can be used for experiments too risky to perform on live humans.

SHE died two decades ago, but her body lives on in digital form. An American woman’s cadaver has been sliced more than 5000 times to create the world’s most detailed digital body. The “human phantom” is available online and will make it possible to perform experiments no live human could undergo.
Not much is known about the woman, not even her name. All we know is that she was obese and died of heart disease at the age of 59 somewhere in Maryland. Her husband gave permission for her body to be used by the Visible Human Project, set up by the US National Library of Medicine in Bethesda, Maryland.
The original aim of the project was to provide digital subjects for medical education, but researchers have since begun to appreciate their potential for modelling dangerous experiments.
When the project began, the bodies of two people, a woman and a man, were imaged extensively using MRI and CT scanning. They were then frozen, thinly sliced and photographed. The first photos were released back in the 1990s, and have been accessed thousands of times for research. Many teams have also pieced together digital versions of the man’s body (see “Digital Frankenstein“).
Now the woman’s body has been recreated, in far greater detail. She has been digitised at a much higher resolution, thanks to the thinner slices used. The male cadaver was sectioned at 1 millimetre intervals; the woman at intervals of just a third of a millimetre.
