The advent of complex surgical procedures has driven the need for realistic surgical training simulators. Comprehensive simulators that provide realistic visual and haptic feedback during surgical tasks are required to familiarize surgeons with the procedures they are to perform. Complex organ geometry inherent to biological tissues and intricate material properties drive the need for finite element...
Realistic surgical simulation should take into account the mechanical properties of soft tissue, and also patient-specific variations. Consequently automated methods are required for the acquisition and modeling of patient-specific tissue properties.We take a step toward this goal by presenting a semiautomated method for acquiring, modeling, and simulating soft-tissue deformation. During a typical...
Mechanical models for soft organ tissues are necessary for a variety of medical applications, such as surgical planning, virtual reality surgery simulators, and for diagnostic purposes. An adequate quantitative description of the mechanical behavior of tissues requires adequate and accurate experimental data to be acquired and analyzed. We present results of three types of ex vivo tests on pig liver...
