This describes initial efforts to use x ray and ct scans to provide a better understanding of the composition of mummy coverings, here a mummy mask or head covering. The primary interest is to try to analyze the texts on the papyrus infrastructure.

5. Identification of internal structure and linen,
papyrus, and ink indications were
observed

6. Indications of text
within the mask

8. CT provides 3-dimensional x-ray
data

9. CT provides 3-dimensional inside
and outside surface data

12. Summary
Currently developing an
advanced tool set to:
Accurately assess mask
construction and areas of
interest prior to extraction
Fully record 3-D Surface Data
Document visual appearance of
the mask for reconstruction and
replication with 3-D printing
Fabricate internal and external
supports for the mask to support
extraction, display, and
transportation
