After watching this video, I have look for publications which describe the techniques used, but I haven't found many detailed publications. However, I found this review publication (Lynnerup, N. (2010). Medical Imaging of Mummies and Bog Bodies – A Mini-Review Gerontology, 56 (5), 441-448 DOI: 10.1159/000266031), which I have read and although not too detailed about the CT scanning procedures, I have learned a few things:
- Living tissues require different processing that dead tissues, because Hounsfield units are different. Bone tends to de-mineralize, while soft tissues tend to become denser (probably due to surrounding minerals).
- Even that this type of scans are done since the 70's, new CT scans are also done, because technology has improved that new findings arise.
- CT data can be easily shared with other scientists, while skulls and mummies can't.
