This project aims to develop a platform for modeling of virtual tissues to be used in simulation of surgical and interventional procedures. The investigative team has made major advances in collection of mechanical tissue properties of the liver, integration into complex constitutive models, re-tooling the hemodynamic simulation model, and delivery of physics based visual models. Moreover, the group has been able to successfully demonstrate interaction of the virtual liver model with external forces including external shock wave and actual ballistic projectile. The results of the work performed during this award period have allowed for a physics-based model of tissue trauma and hemorrhage based on actual physical properties of the liver in a viscoelastic model, with superimposed hemorrhage using a smooth particle hydrodynamics method, in order to generate a high-fidelity virtual model of the said organ.
