Axial thin-collimation state-of-the-art spiral computed tomography (CT) was combined with sagittal and coronal reformatting, three-dimensional (3D) reconstruction, and virtual "fly-through" techniques to nondestructively study nine Egyptian mummies. These techniques provided important paleopathologic and historical information about mummification techniques, depicted anatomy in the most informative imaging plane, illustrated the soft-tissue preservation and physical appearance of mummies in superb detail, and generated an intriguing virtual tour through hollow mummified remains without harming the specimens themselves. Images generated with these methods can help archaeologists and Egyptologists understand these fascinating members of mankind and can serve as adjunct visual aids for laypersons who are interested in mummies. CT has emerged as the imaging modality of choice for the examination of Egyptian mummies due to its noninvasive cross-sectional nature and inherently superior contrast and spatial resolution. As multi-detector row CT and postprocessing tools evolve, the capabilities and applications of CT will continue to proliferate, attesting to the expanded versatility and utility of CT as a noninvasive research tool in the multidisciplinary study of Egyptian mummies.
轴向薄层准直的先进螺旋计算机断层扫描（CT）与矢状面和冠状面重新格式化、三维（3D）重建以及虚拟“飞越”技术相结合，对九具埃及木乃伊进行了无损研究。这些技术提供了有关木乃伊制作技术的重要古病理学和历史信息，在信息量最大的成像平面上描绘了解剖结构，极其详细地展示了木乃伊的软组织保存情况和外观，并在不损害标本本身的情况下，通过中空的木乃伊残骸生成了引人入胜的虚拟游览。用这些方法生成的图像有助于考古学家和埃及古物学家了解人类这些迷人的成员，也可为对木乃伊感兴趣的外行人士提供辅助视觉帮助。由于CT具有无创性横断面性质以及固有的卓越对比度和空间分辨率，它已成为检查埃及木乃伊的首选成像方式。随着多排探测器CT和后处理工具的不断发展，CT的功能和应用将持续增加，这证明了CT作为一种无创研究工具在埃及木乃伊多学科研究中的通用性和实用性不断扩大。
