More re Terahertz imaging to view mummies

Preserved bodies help doctors understand diseases that have plagued humans for thousands of years

Back in 2005, when Frank Ruhli was trying to figure out how ancient Egypt's famous boy pharaoh, King Tut, died, he used CT scans of Tut's mummified remains. Now, says the renowned mummy expert, the new technology to screen some airline passengers for explosives can provide even more information.

"By applying this technology on top of another technology, it may help you to look differently at the specimen," he explains, adding that the Terahertz imaging - also known as "full body scan" technology - does not use any sort of radiation, which could destroy DNA remnants of the mummies.

"And finally, by using this Terahertz imaging, you eventually may be able to look at the substances within the mummy, for example, the embalming liquid used in the Egyptian way of embalming. There you can actually do sort of substance analysis which you can't really do by conventional x-ray."
