Accuracy of the anthropometric measurements of skeleton-ized skulls with corresponding measurements of their 3D reconstructions obtained by CT scanning

摘要

Purpose: The anthropometric measurements of the skeletonized skull are crucial in the investigation of human remains, mostly for personal identification. The images of the skull are used if the superimposition or approximation of the facial appearance is to be performed. The aim of the study was to compare the accuracy of the anthropometric measurements of skeletonized skulls with corresponding measurements of their 3D reconstructions obtained by CT scanning. Methods: Ten skeletonized skulls and their 3D digital reconstructions were measured according to standard anthropometric procedures. The results were compared and statistical analysis was performed. Results: The statistical analysis revealed that the 3D reconstruction is absolutely reliable for any measurements within the skull. The results of the measurements obtained from the CT image were accurate and comparable to the results of the anthropometric analysis of the skeletonized skull. The correlation between the anthropometry of the skeletonized skulls and the CT reconstructions was strong. Conclusions: It is relevant that 3D reconstructions of the skull can be used in forensic anthropology for personal identification.
