Abstract

With the widespread use of postmortem computed tomography (PMCT) beside forensic autopsies for investigation of causes of death, three-dimensional (3D) reconstruction and fusion imaging using PMCT data are now becoming common. In the present study, the applicability of virtual reassembly from PMCT data was investigated in three cases involving fragmentation of the skull or spine due to high-energy trauma, as in such cases it is sometimes difficult to obtain detailed information on fractures using macroscopic observation alone. In the first case, virtual reassembly of the skull provided more information about the fractures than conventional reconstruction with adhesive. In the second case, although the skull was severely fractured and could not be examined macroscopically, virtual reassembly allowed detailed visualization of the fractures. In the last case, virtual reassembly of the spine helped to clarify that the 6th–8th thoracic vertebrae had been run over by a vehicle at the scene. Thus, virtual reassembly was shown to be useful for assessment of injury patterns, and event reconstruction.
