This study introduces a 3D system for visualizing gunshot and stab wound paths. The tool aids in identifying affected anatomical structures for forensic analysis.

Area of Science:

  • Forensic Science
  • Medical Visualization
  • Computer Graphics

Background:

  • Accurate determination of wound trajectories is crucial in forensic investigations.
  • Existing methods for analyzing wound paths can be complex and time-consuming.
  • 3D visualization offers potential for improved clarity and analysis.

Purpose of the Study:

  • To develop a 3D graphical system for visualizing penetration path hypotheses of wounds.
  • To automatically identify anatomical structures affected by hypothesized wound paths.
  • To enhance the analysis of complex wound scenarios, including multiple injuries.

Main Methods:

  • Utilized a 3D graphical model of the human body with detailed anatomical structures.
  • Developed a system to generate penetration path hypotheses from surface wound data using combinatorial analysis.

Related Experiment Videos

  • Implemented an interpenetration analysis algorithm to determine affected anatomical structures for each path hypothesis.

    • Main Results:

    • The system successfully visualizes multiple penetration path hypotheses for gunshot and stab wounds.
    • Accurate identification of anatomical structures impacted by each hypothesized wound path was achieved.
    • The 3D graphical representation aids in understanding complex wound ballistics and injury patterns.

    Conclusions:

    • The developed 3D system provides a valuable tool for forensic experts.
    • This visualization system enhances the interpretation of wound evidence.
    • The approach offers a more objective and detailed method for reconstructing injury events.
