Real-time, three-dimensional (RT3D) ultrasound allows video frame rate volumetric imaging. The ability to acquire full three-dimensional (3-D) image data in real-time is particularly helpful for applications such as cardiac imaging, which require visualization of complex and dynamic 3-D anatomy. Volume rendering provides a method for intuitive graphical display of the 3-D image data, but capturing the RT3D echo data and performing the necessary processing to generate a volumetric image in real time poses a significant technical challenge. We present a data capture and rendering implementation that uses off-the-shelf components to real-time volume render RT3D ultrasound images. Our approach allowed live, interactive volume rendering of RT3D ultrasound scans.
实时三维（RT3D）超声可实现视频帧率容积成像。实时获取完整的三维（3-D）图像数据的能力对于诸如心脏成像等应用特别有帮助，这些应用需要可视化复杂且动态的三维解剖结构。容积再现提供了一种直观图形显示三维图像数据的方法，但实时捕获RT3D回波数据并进行必要的处理以生成容积图像带来了重大的技术挑战。我们展示了一种数据捕获和再现实现方法，该方法使用现成的组件对RT3D超声图像进行实时容积再现。我们的方法实现了RT3D超声扫描的实时、交互式容积再现。
