CT scan seeks secrets of 700-year-old mummy

Scientists at the Smithsonian Institution's National Museum of Natural History are using a CT scanner to investigate mummies, spacesuits, pottery, antique violins, and other priceless objects.
The researchers say the scanner produces highly accurate, high definition three-dimensional images that enable them to study the objects in detail without having to cut them open.
Dr Bruno Frohlich, a physical anthropologist with the museum, says researchers plan to use the scanner to study a 700-year-old Peruvian mummy. They have already determined its internal organs are intact, and Dr Frohlich says the studies could shed light on how the woman lived - and died.
"We could probably do the same with a traditional autopsy," says Dr Frohlich, "but there would be nothing left for future generations and it would destroy something that should not be destroyed."
