Use of Computed Tomography scanning in a 'virtual' bioarchaeology of care analysis of a Central Coast Peruvian mummy bundle.

Background: CT scanning was utilized to investigate an intact mummy bundle within the bioarchaeology of care framework. The project sought to ascertain whether a 'virtual' analysis was feasible, thereby avoiding physical disturbance to bundle structure and contents.

Methods: The bundle selected for this study contained an adult male (FA 54), Ichma culture, Peru, displaying evidence for two pathologies: chronic osteomyelitis of the right tibia, and cranial trauma. CT images provided the basis for bioarchaeology of care analysis, which followed Index of Care protocols.

Results: CT images enabled description and diagnosis of FA 54, and revealed human neonate remains and material artifacts within the bundle. Probable disease impacts were identified, and likely forms of care provided were inferred. CT scanning was of limited value in identifying characteristics of textile wrapping (a clue to cultural identity) and in resolving questions regarding funerary treatment (primary vs. secondary burial), and this constrained consideration of wider social implications of caregiving.

Conclusion: 'Virtual' examination of FA 54 achieved an advanced stage of bioarchaeology of care analysis, but building on this would require physical examination of bundle elements. Further investigation of CT imaging potential for bioarchaeology of care research in mummy studies is recommended.
