Intact mummies are often examined with computed tomography, but many of the objects and materials found within the intact cartonnage or wrappings are unknown. We acquired CT scans of two Egyptian mummies (Third Intermediate Period, Dynasty 22 and Ptolymeic era) at 4 energies (80, 100, 120 and 140 kVp). These spectral data sets were calibrated using scans of ancient Egyptian objects with known composition and other reference materials to understand the mummified contents. We demonstrate how multi energy CT images can characterize the contents of Egyptian Mummy CT scans. Spectral CT allows visualization and analysis of materials used in the mummification process.  

Introduction: • History of mummification processes used in ancient Egypt • CT scanning of mummies • Spectral CT technology Spectral CT Imaging of Egyptian mummies • Differences found at 80 vs 140 kVp • Pseudocolor visualization of mummy contents • Multispectral material analysis method • Calibration of multienergy CT using ancient Egyptian objects with known composition Results of spectral CT scans for two Egyptian mummies • Third Intermediate Period, Dynasty 22 mummy • Ptolymeic era mummy Recommendations for future CT scans of Egyptian mummies
