A Critical Look at Mummy CT Scanning

Area of Science:

• Paleoradiology
• Bioarchaeology
• Egyptology

Background:

• Computed tomography (CT) scanning has been utilized in mummy studies for nearly 40 years.
• Modern high-definition CT scans offer extensive data, yet their full potential remains underexploited.
• Current interpretations often overlook taphonomic and mummification effects on ancient tissues.

Purpose of the Study:

• To critically assess the evolution and application of CT scanning in mummy research.
• To highlight the potentials and challenges of high-resolution CT scanning in interpreting mummified remains.
• To address the limited understanding of how postmortem processes affect CT imaging of mummies.

Main Methods:

• Review of the historical development of CT scanning techniques for mummy analysis.
• Case study involving high-resolution CT scanning of two Egyptian mummies at the Penn Museum.
• Analysis of CT data to identify taphonomic and mummification-induced alterations in ancient tissues.

Main Results:

• CT scanning provides detailed, non-destructive insights into mummy morphology and preservation.
• Interpreting mummy CT scans requires careful consideration of postmortem changes (taphonomy and embalming).
• The study identified specific image artifacts and tissue alterations resulting from mummification processes.

Conclusions:

• CT scanning is a powerful tool for mummy research, but requires specialized interpretive frameworks.
• Understanding taphonomy and mummification is crucial for accurate analysis of mummy CT data.
• Further research is needed to establish standardized protocols for mummy CT interpretation.
