title: [Application of multi-slice computed tomography in biomechanical analysis of traffic accidents].
abstract: OBJECTIVE
  To study the application value of multi-slice computed tomography (MSCT) and 3D reconstruction in biomechanical analysis of traffic accidents in forensic medicine.
  
  
  METHODS
  Based on a real case, the tomoscan images were obtained from a corpse by MSCT scanning. The 3D images were reconstructed. The biomechanic process of injury manners of impacting, rolling and crushing in traffic accidents was analyzed together with autopsy, vehicle inspection, etc. The MSCT results were compared with the autopsy results.
  
  
  RESULTS
  Some characters in situ including the part of fracture on different site that suffered by force from different directions, trends of fracture line, and status of smash inner bones were obtained trough MSCT and 3D reconstruction. Some details like fracture were even better than those from autopsy.
  
  
  CONCLUSIONS
  MSCT and 3D reconstruction have some advantages such as in situ reconstruction, easily controlled image and fully conserved evidence. It may be a supplementary method and have a directive function for the biomechanical analysis of traffic accidents.
