Description:


    Pre-operative evaluation of surgical strategies is of utmost impor-tance in many areas of surgery. This is especially 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 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 for a 10-year-old girl. From three-dimensional MRI data, a detailed model of the patient-specific anatomy is obtained. A diagno-sis 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 neccessary to accurately understand the anatomi-cal details, real-time convergence could not be achieved by existing CPU implementations. Dedicated software was developed and run on a 3 GHz Pentium 4 PC with an NVIDIA Geforce 6800 Ultra graph-ics card.

Hardware:


    PC, Pentium 4, 3 GHz, 1 GB RAM, Geforce 6800 Ultra graphics card, Polhemus Fastrak for interaction

Software:


    Adobe Premier Pro, Adobe After Effects, Adobe Photoshop, Deep Exploration, Virtual Reality Heart by Systematic Software Engineering, custom volume rendering and MRI reformatting software, custom GPU-based surgical simulator
