Simulation and visualization to support breast surgery planning

Today, breast surgeons plan their procedures using preoperatively placed metal clips or radioactive seeds and radiological images. These images show the breast in a positioning different from the one during surgery. We show a research prototype that eases the surgeonâs planning task by providing 3D visualizations based on the radiological images. With a FEM-based deformation simulation, we mimic the real surgical scenario. In particular, we have developed a ligament model that increases the robustness of a fully automatic prone-supine deformation simulation, and we have developed specific visualization methods to aid intra-operative breast lesion localization.
