Fast physics-based simulation of vascular surgery

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.
