Tagging acquisition of the orbit during eye movement have proven to give new inside into the mechanical properties of orbital tissues, and to be a valuable tool for investigating ocular diseases etiologies. 3D tagging acquisition have been shown to be feasible. We present here a model-free method enabling to quantify out of 3D tagging data the inhomogeneous deformation along extraocular muscles. This tool able 3D strain quantification and is adaptable to other tissues, like the heart.
