Certain types of diseases lead to changes in the microstructural organization of tissue. Altered microstructure in turn leads to altered macroscopic tissue properties, which are often easier to image than the microstructure itself. Thus the measurement of macroscopic properties offers a window into tissue microstructure and health. In Biomechanical Imaging (BMI) we aim to utilize this association between the macroscopic mechanical properties of tissue and its health by using generating images of the mechanical properties and using these to infer tissue microstructure and health. At the heart of BMI lies the solution of an inverse problem in continuum mechanics; given the deformation of the medium (tissue) and constitutive model, determine the spatial distribution of the material properties.
