1 Weapon identification using antemortem computed tomography with virtual 3D and rapid prototype modeling—A report in a case of blunt force head injury  Krzysztof Woźniak, Ewa Rzepecka-Woźniak, Artur Moskała, Jerzy Pohl, Katarzyna Latacz, Bogdan Dybała  Forensic Science International  Volume 222, Issue 1, Pages e29-e32 (October 2012) DOI: /j.forsciint Copyright © 2012 Elsevier Ireland Ltd Terms and Conditions

2 Fig. 1 3D volume rendered images of the skull based on the clinical CT scans: (a) right posterolateral view and (b) superior view. Open arrows indicate the two centers of impact and intrusion.

3 Fig. 2 3D volume rendered image of the skull based on the clinical CT scans, internal view of the right side of the skull, with the left side of the skull digitally removed. Open arrows indicate fracture apices. Forensic Science International  , e29-e32DOI: ( /j.forsciint ) Copyright © 2012 Elsevier Ireland Ltd Terms and Conditions

4 Fig. 3 Superimposition of virtual 3D objects from surface rendered clinical CT data of the skull and the scan of one potential weapon, views include: (a) the right lateral, (b) superior view, (c) right anterolateral, and (d) right posterolateral.
