We present an algorithm for determining the acceleration field of a rigid body using
measurements from four tri-axial accelerometers. The acceleration field is an important
quantity in bio-mechanics problems, especially in the study of mild traumatic brain injury
(mTBI). The in vivo strains in the brain, which are hypothesized to closely correlate with brain
injury, are generally not directly accessible outside of a laboratory setting. However, they
can be estimated on knowing the head's acceleration field. In contrast to other techniques …
