The quadriceps muscle plays an extremely critical role in various aspects of human locomotion. Changes in its function from various disease such as aging, muscular disuse or modified gait can degrade mobility. VE-PC imaging provides a convenient way to study muscle motion and assess the relative contribution of the thigh muscles to force production. This study is focused on deriving the strain and strain rate tensors to explore patterns along the fiber direction and cross-section. We were able to successfully obtain strain tensor images as well as to follow the temporal variation of these indices in different muscle compartments.
