Combining Rheometry and Elastography to Understand Large Deformation Soft Tissue Properties

Accurate mechanical properties of tissues are essential for inclusion in computational models of impact injury. High quality large deformation (i.e. nonlinearly viscoelastic) tissue properties at high strain rates relevant to injury are limited in literature and this is mostly due to the complexities characterizing nonlinear viscoelastic properties past the linear viscoelastic limit, and experimental challenges at high loading rates. The authors suggest a method of combining static compressive preload and high frequency shear strain to understand large deformation tissue properties in vivo. The authors investigated this method in stages, combining ex vivo rheometry and Magnetic Resonance Elastography (MRE) tests under static preload, and also demonstrated proof of principle in in vivo MRE data.
