We exploit consumer graphics hardware to perform real-time processing and visualization of high-resolution, 4D cardiac data. We have implemented real-time, realistic volume rendering, interactive 4D motion segmentation of cardiac data, visualization of multi-modality cardiac data and 3D display of multiple series cardiac MRI. We show that an ATI Radeon 9700 Pro can render a 512x512x128 cardiac Computed Tomography (CT) study at 0.9 to 60 frames per second (fps) depending on rendering parameters and that 4D motion based segmentation can be performed in real-time. We conclude that real-time rendering and processing of cardiac data can be implemented on consumer graphics cards.
我们利用消费级图形硬件对高分辨率4D心脏数据进行实时处理和可视化。我们已经实现了实时、逼真的体绘制、心脏数据的交互式4D运动分割、多模态心脏数据的可视化以及多个系列心脏MRI的3D显示。我们表明，根据渲染参数，ATI Radeon 9700 Pro显卡能够以每秒0.9至60帧（fps）的速度渲染512x512x128的心脏计算机断层扫描（CT）研究数据，并且基于4D运动的分割可以实时进行。我们得出结论，心脏数据的实时渲染和处理可以在消费级图形卡上实现。
