Abstract Scope |
X-ray imaging of dynamic events has evolved in recent decades from the traditional sequencing of flash x-ray images to utilizing continuous x-ray sources and synchrotrons in combination with scintillator screens and high-speed cameras to capture dynamic events at frame rates on the order of 102-106 s-1. High-speed x-ray (HSX) imaging produces a single imaged plane for the duration of a dynamic event and is advantageous for tracking the motion of non-symmetric objects. In this study, a HSX system at TNO (Netherlands) is used to image ballistic impacts on a commercially available helmet backed by a 3D printed frangible human skull surrogate system developed at DEVCOM U.S. Army Research Laboratory. The HSX videos allow for quantitative analyses of the evolving helmet backface and subsequent interactions with the frangible skull surrogate that are otherwise not achievable via synchrotron sources (field-of-view limitations) or flash x-rays (limited frames and varying imaging planes). |
