Three-dimensional reconstruction of medieval child mummy in Yangju, Korea, using multi-detector computed tomography.

Recently reported studies on the medieval mummies in Korea have been regarded as an invaluable source for studying the physical characteristics of medieval Koreans. However, since the reported medieval mummies were re-buried by their descendants without any scientific investigations, the development of a brief, non-invasive investigation technique was desperately needed among the researchers in Korea. In this regard, we tried to apply high-quality multi-detector computed tomography (MDCT) with three-dimensional (3D) reconstructions and multi-planar reformat (MPR) to investigate Korean mummies. In our study, after 1.25 or 2.5mm thin slice axial images were taken, 3D reconstruction and MPR were performed to get more accurate information about internal organs. In this trial, we successfully showed high-quality images for the brain, muscles, bones, heart and liver. During various trials for getting selected organs, we could make the 3D reconstructed images of them. Since we could show that the current MDCT technique could be useful for obtaining high-quality 3D reconstructed images of the internal organs of Korean mummies, this technique will be used in forthcoming similar cases, which could not be investigated using invasive techniques.
