Comparison of two approaches to breast deformation modelling based on a biomechanical model

According to recent studies, breast cancer is the most frequent women's cancer around the world. Fast and precise diagnosis and personalized treatment procedures are crucial in the face of the growing number of patients. One of the most informative and at the same time non-evasive diagnostic techniques is based on Magnetic Resonance Imaging (MRI). This examination is performed basically in prone position due to better visualisation of breast tissues as well as the proper magnetic coil force this position. On the other hand supplementary imaging techniques (e.g. Computer Tomography (CT) or Positron Emission Tomography (PET)) and, what is the most important, surgery are performed in supine position. Since changing position from prone to supine leads to breast deformation, we propose an algorithm based on finite element method (FEM) to model it. We compare our results with model created in ANSYS.
