可以利用用户交互性实时地创建和显示来自磁共振成像数据的体积渲染。这可以提供连续的3D反馈以帮助引导介入流程。本文介绍了一种能从二维多切片或三维磁共振脉冲序列产生实时体绘制的系统。成像帧速率高达每秒30帧，延迟约为三分之一秒，具体取决于图像矩阵大小。已经实现了几种交互功能来增强可视化，例如切割平面、单个通道缩放和颜色突出显示、视图共享、饱和度准备、复杂减影、门控控制以及alpha混合或MIP渲染的选择。该系统的描述和一些介入应用的例子。要查看某些示例的影片，请在Web浏览器中输入以下地址：http://nhlbi.nih.gov/labs/papers/lce/guttman/ rtvolmri/index/htm。
Volume renderings from magnetic resonance imaging data can be created and displayed in real-time with user interactivity. This can provide continuous 3D feedback to assist in guiding an interventional procedure. A system is presented which can produce real-time volume renderings from 2D multi-slice or 3D MR pulse sequences. Imaging frame rates up to 30 per second have been demonstrated with a latency of approximately one-third of a second, depending on the image matrix size. Several interactive capabilities have been implemented to enhance visualization such as cut planes, individual channel scaling and color highlighting, view sharing, saturation preparation, complex subtraction, gating control, and choice of alpha blending or MIP rendering. The system is described and some interventional application examples are shown.
