Virtopsy: Experimental study of measurement tolerances in the processing and post-processing system of biomodels for forensic applications.

Abstract

Virtopsy, an innovative non-invasive post-mortem imaging technique, offers a new approach to forensic examination. However, the accuracy of measurements obtained from 3D models reconstructed from CT scans is significantly influenced by the technical characteristics of the scanners employed. This study assessed the impact of two different-generation CT scanners on measurement variability, highlighting how each scanner introduces a "characteristic error". The results emphasize the need for standardized acquisition protocols and the development of correction methods to ensure the reliability of digital evidence in forensic investigations. The ultimate goal is to promote the acceptance of virtopsy as a valid and reliable tool in forensic medicine.
