Background Noninvasive measurement of internal dynamic strain can be potentially useful to characterize spine intervertebral disc (IVD) in the setting of injury or degenerative disease. Purpose To develop and demonstrate a noninvasive technique to quantify three‐dimensional (3D) internal dynamic str...
