Virtual autopsies use MRI and CT scans for non-invasive examination of cadavers. Image processing detects metal objects, aiding in developing better safety devices and reducing deaths.

Area of Science:

  • Forensic science
  • Medical imaging
  • Radiology

Background:

  • Diagnostic radiology devices like MRI and CT are increasingly used in forensic investigations.
  • Virtual autopsy offers a cost-effective, non-invasive alternative or supplement to traditional autopsies.

Purpose of the Study:

  • To explore the application of virtual autopsy in forensic investigations.
  • To develop image processing techniques for identifying forensically relevant information, specifically metal objects.
  • To analyze findings for improving safety and protection devices.

Main Methods:

  • Utilizing magnetic resonance imaging (MRI) and computed tomography (CT) for cadaver imaging.
  • Developing advanced image processing algorithms for metal object detection and characterization.
