Terminal ballistics concerns the science of projectile behaviour within a target and includes wound ballistics that considers what happens when a projectile strikes a living being. A number of soft tissue ballistic simulants have been used to assess the damage to tissue caused by projectiles. Standard assessment of these materials, such as ballistic soap or ordnance gelatine, requires the block to be opened or that a mould to be made to visualize the wound track. This is time consuming and may affect the accuracy of the findings especially if the block dries and alters shape during the process. Therefore, accurate numerical analysis of the permanent or temporary cavity is limited. Computed tomography (CT) potentially offers a quicker non-invasive analysis tool for this task. Four commercially purchased ballistic glycerine soap blocks were used. Each had a single firearm discharged into it from a distance of approximately 15 cm using both gunshot and shotgun projectiles. After discharge, each block was imaged by a modern 16 slice multi-detector CT scanner and analysed using 3-D reconstruction software. Using the anterior-posterior and lateral scout views and the multi-plane reconstructed images, it was possible to visualize the temporary cavity, as well as the fragmentation and dispersal pattern of the projectiles, the distance travelled and angle of dispersal within the block of each projectile or fragment. A virtual cast of the temporary cavity can be also be made. Multi-detector CT with 3-D analysis software is shown to create a reliable permanent record of the projectile path allowing rapid analysis of different firearms and projectiles.
In a suicidal shot to the temple two roundish zones of powder soot blackening were found above the entrance wound. The paired zones of powder soot blackening were caused by two gas outlets located on the upper side of the muzzle end of the weapon used (converted blank cartridge pistol of make Rhöner). The conclusions that can be drawn from this particular soot pattern with regard to the type of the weapon, the muzzle-to-target distance, the direction of fire and the way of holding the weapon are discussed.
BACKGROUND: This study was undertaken to examine the distribution of entry wounds resulting from firearms and shrapnel in soldiers wearing military personal armor systems (MPAS) in low-intensity urban combat conditions. METHODS: Data were collected for a retrospective analysis on all combat fatalities sustained by the Israeli Defense Force (IDF) between March 30, 2002, and April 22, 2002, during Defensive Shield Operation in the West Bank. Twenty-six of the 30 fatalities were evaluated in the Israeli National Center of Forensic Medicine. RESULTS: A total of 149 entrance wounds were divided into shrapnel and bullet groups. The "face-neck" region had the highest density rate compared with other body regions in both shrapnel and bullet groups (2.97 and 2.41, respectively; p < 0.0001). In both groups, the overall prevalence of anterior injuries was significantly higher than posterior ones (78.9% vs. 21.1% in the shrapnel group and 68.5% vs. 31.5% in the bullet group, p < 0.001). However, anterior and posterior chest injuries had a reverse yet more even distribution (43.8% and 56.2% in the bullet group and 40% and 60% in the shrapnel group, respectively; p < 0.001). The difference in the average diameters of entry wounds in the covered versus uncovered regions (0.79 +/- 0.42 cm vs. 0.73 +/- 0.29 cm, respectively) was not statistically significant (p = 0.11). CONCLUSION: The use of MPAS turned the face-neck region into the most vulnerable body part, as shown by its prominent density rate, especially in the shrapnel group. MPAS designed for urban setting warfare should provide maximal shielding both to the anterior and posterior chest regions. The diameter of entrance wounds in the covered versus the uncovered areas was not statistically significant, suggesting that only a minor deformation of the bullet takes place while traversing the Kevlar vest.
