ABSTRACT

The study aimed at examination of the possibilities of using photogrammetry methods followed by 3D modeling of the wound channel and acute traumatic object during forensic medical examinations of stab wounds of soft tissues and parenchymal organs. The study was conducted on a series of 15 experimental and practical cases of stab wounds. Experimental wound channels were manufactured using alginate imprint mass with rubber-like effect “Hydrogum 5" (“Zhermack”, Italy) and barbed tool with the one-sided sharpening of the blade. During the program investigation of 3D models of experimental wound channels, the linear dimensions of individual morphological parts of the wound channel were obtained with an accuracy of 0.001 cm, which allowed us to identify the instrument which caused the injury with a high probability. Taking into account the reliable results obtained in the experiment, this technique was used during the forensic medical examination of stab kidney wound, which allowed identifying the instrument of injury from among the provided ones by the investigating authorities for forensic examination of razor-barbed tools.
