Sub-surface analysis of ancient human remains using a robotic-based THz system

We used THz time-domain imaging with a robotic-based THz system for a tomographic reconstruction of the subsurface structure of an artificially mummified ancient Egyptian human left hand. A comparison between the THz tomography data and a conventional CT and a micro-CT scan reveals, that the depth resolution of the THz images exceeds the resolution of a conventional CT scan and is comparable with a micro-CT scan. Using such a robotic-based THz system promises new insights into the sub-surface structure of human remains.
