| Minimally invasive vascular surgery has been shown to be effective for the treatment of vascular or artery diseases. However, extensive training and careful planning are needed for a successful operation due to its inherent problems including non-co-located hand-eye coordination, restricted vision of anatomical environment, and the absence of tactile feedback. Virtual reality medical simulation can potentially provide a safe and robust solution to the training of clinicians.;In order for the training to be effective, the simulation should be physics-based with real-time computer graphics rendering so as to be realistic. This dissertation focuses on the study of fast physics-based simulation of vascular surgery on three important aspects: (1) realistic and interactive simulation of blood vessel deformation using an improved lumped element method, (2) fast hemodynamic simulation in patient-specific model using meshfree method, and (3) simulation of surgical smoke during the surgery.
