Simulation of real-time deformable soft tissues for computer assisted surgery.

The simulation of realistic surgical procedures requires specialized optimized algorithms for the models of organs and tissues, which should comply both with accuracy of results and run-time computation. This paper provides a general survey of methods and approaches used for the simulation of soft tissues in Computer Assisted Surgery, discussing the technological challenges to achieve realistic simulation of deformation.An application example is presented, referring to the simulation of a gastroenterology procedure, abdominal paracentesis for the treatment of ascites.
