Modeling internal ballistics of gas combustion guns.

Potato guns are popular homemade guns which work on the principle of gas combustion. They are usually constructed for recreational rather than criminal purposes. Yet some serious injuries and fatalities due to these guns are reported.

Sturdivan's formula revisited: MRI assessment of anterior chest wall thickness for injury risk prediction of blunt ballistic impact trauma.

Background: The thickness and composition of the chest wall are important quantities in multiparametric trauma models for the assessment of injury severity due to blunt ballistic chest impact. While ballistic parameters of non-penetrating projectiles can routinely be measured with high accuracy, data on the thickness of the anterior chest wall is unreliable. Therefore, it is the aim of this work to provide data on the thickness and composition of the anterior chest wall based on MRI examinations of healthy volunteers and to compare these measurements with different empirical estimation rules for the chest wall thickness.
