Abstract
Biomechanical models of the breast can be used to co-locate information between the various medical images to identify tumour locations, while also providing the ability to predict their locations during surgical procedures. We have created subject-specific, heterogeneous 3D finite element (FE) models of breast biomechanics to provide the ability to predict breast deformation under different loading conditions. We have verified the applicability of such modelling for simulating the prone to supine reorientation of the breast and obtained good agreement to ground-truth supine images obtained from breast MRI. In particular, we highlight the importance of modelling the pectoral muscles for gravity loading simulations.
