Siemens experts have been examining the mummified remains of the pharaoh Tutankhamun in a CT scanner - with unprecedented precision. Together with the Egyptian chief archaeologist, Dr. Zahi Hawass, they want to determine the cause of Tutankhamun’s death more than 3,000 years ago. It was the first time since the mummy’s discovery in 1922 that it had been removed from its resting place in the Valley of the Kings near Luxor. In 1968 the first X-ray analysis of the head revealed that the pharaoh might have died as a result of a severe blow.
