Two technologies which had been adapted for imaging use the examination and documentation of heritage artefacts.

Tetra-hertz technology had been previously developed for airport security screening (see previous New Scientist article here) - albeit, too successfully, one might add. The advantage is that the energy source is considered safe for humans.

The second uses a combination of x-ray and computed tomography to give a resultant three-dimensional image that would be immensely more viewable and, hence, more useful than conventional x-ray images.
