| Popis: | The objective of this experimental study was to develop a new method in terminal ballistics that would allow for precise numerical analysis of the characteristics of permanent cavity by use of computed tomography. Shots were made with Russian AK-74 assault rifle (5.45 mm) into gelatin blocks. Computed tomography scans of the blocks were obtained, translated to digital format, and analyzed using computer software. The area of selected cross-sections of the wound channel was calculated. Maximal destruction of the tissue simulant was recorded between 180 and 220 mm of the missile trajectory. Total and segmental areas of the tissue simulant destruction and missile directions showed significant variation. The method was found to measure terminal ballistic phenomena of the wound channel with considerable precision. It would allow for the effects of different weapons to measure, with implications for the understanding and treatment of gunshot wounds. Cilj ove eksperimentalne studije bio je razvoj nove metode u terminalnoj balistici, koja će omogućiti preciznu brojčanu analizu značajki permanentne kavitacije pomoću kompjutorizirane tomografije. Za potrebe ispitivanja provedeno je pucanje iz ruske automatske puške AK 74 (5.45 mm) u želatinske blokove. Blokovi su snimljeni kompjutoriziranom tomografijom, a slike su prebačene u digitalni oblik i analizirane primjenom kompjutorskog programa. Izračunate su površine presjeka strijelnog kanala. Najveće oštećenje tkivnog simulanta bilo je vidljivo između 180 i 220 mm putanje projektila. Ukupne i segmentne površine razaranja tkivnog simulanta i smjerovi putanje projektila pokazali su značajne varijacije. Zaključeno je kako navedena metoda mjeri terminalno balističku pojavu strijelnog kanala sa značajnom preciznošću. Moguće je mjeriti učinke različitih oružja simplikacijama za razumijevanje i liječenje strijelnih rana. |
