Synopsis

The 4D CS-Flow sequence can be applied to image calf muscle motion during isometric contraction in order to extract 3D Strain tensors. The ability to extract the full 3D strain tensors should enable one to answer questions related to muscle deformation anisotropy in the transverse plane, volumetric strain and maximum shear strains.
