Purpose Synchronous measures of head kinematics and in vivo brain deformation during rapid head rotation are needed to advance understanding of traumatic brain injury (TBI) mechanics and enhance computational modeling as a tool for injury risk assessment and prevention. The aims of this study were to produce repeatable rapid rotation of the in vivo sheep head, to assess the viability of the sonomicrometry method for measuring...

Porcine models in injury biomechanics research often involve measuring head or brain kinematics. Translation of data from porcine models to other biomechanical models requires geometric and inertial properties of the pig head and brain, and a translationally relevant anatomical coordinate system (ACS). In this study, the head and brain mass, center of mass (CoM), and mass moments of inertia (MoI) were characterized, and an ACS...
