Description:


    Pre-operative evaluation of surgical strategies is of utmost importance in many areas of surgery. In particular this is true for surgery in congenital heart disease, where the complex morphology varies from individual to individual. This animation shows how interactive, real-time computer graphics is emerging in the fields of diagnostics and surgery planning in congenital heart disease. Using magnetic resonance imaging (MRI), volume rendering, and a GPU-based surgical simulator, we follow the treatment considerations of a ten-yea old girl with congenital heart disease. From three-dimensional MRI
    data, a detailed model of the patient-specific anatomy is obtained. The diagnosis is obtained from the MRI data and the reconstructed model. Surgical strategies are subsequently explored in the simulator. A spring-mass based physical simulation is resolved entirely on the GPU in real-time. For a complex organ like the heart, where a highly detailed model is necessary to model the anatomical details accurately, real-time convergence would not be achieved by existing CPU implementations.
