Simulação de cirurgia mamária usando Elementos Finitos com modelos reconstruídos a partir de mamografias

Abstract

Surgery simulation is as a powerful tool to aid health care professionals. Among its applications, we can highlight virtual training, preview of surgery outcome, support for the choice of best procedure and doctor-patient communication improvement. This work presents a methodology for breast surgery simulation using solid nite elements. We build the models from mammographic images. We discuss all the steps required to build the breast nite elements model: image segmentation, breast volume reconstruction, surface mesh extraction, volume mesh generation, and breast materials de nition. The surgery is simulated by tissue removal and suture operations. An application to de ne the models was developed and the Abaqus suite is used to perform the simulations.
