Application of superimposition-based personal identification using skull computed tomography images.

Area of Science:

• Forensic Anthropology
• Medical Imaging
• Digital Forensics

Background:

• Skull-facial superimposition is a key method for personal identification of unidentified skeletal remains.
• Traditional methods require a physical skull, limiting application when only digital data is available.

Purpose of the Study:

• To evaluate the efficacy of using three-dimensional (3D) skull images, reconstructed from computed tomography (CT) scans, for personal identification.
• To compare the accuracy of 3D image superimposition with traditional methods using real skulls.

Main Methods:

• CT scanning of skeletonized skulls from unidentified corpses.
• Reconstruction of 3D skull models from CT data.
• Superimposition of 3D skull models with ante-mortem facial photographs.

Main Results:

• 3D-reconstructed skull images showed morphological consistency comparable to real skulls when superimposed with facial images.
• The digital superimposition technique proved effective for personal identification.
• Reconstructed 3D skull images can be stored as data files for future use.

Conclusions:

• 3D skull image reconstruction from CT scans is a viable and effective tool for personal identification.
• This digital approach overcomes limitations of traditional methods, enhancing identification capabilities for unidentified bodies.
