Measuring material properties of the human brain in vivo

Despite being critical to biomechanical models, material properties of the brain remain poorly understood and have been characterized variously in part because of limited access to the in vivo brain. We use a simple indentation technique feasible in the operating room coupled to a noninvasive stereovision system to induce and measure brain surface deformation in patients undergoing open cranial surgeries in order to estimate material properties of the human brain in vivo.
