A new research tool, the Weighted Head Accelerator Mechanism (WHAM), is described. The WHAM, used together with a custom MRI sequence, permits in depth investigations into brain biomechanics during mild head rotations and the evaluation of mild traumatic brain injury mitigating strategies by directly evaluating their effects on brain biomechanics in vivo.
