Intraoperative MRI has recently entered the operating room as a new imaging modality. Customized visualization systems might further facilitate the use of this imaging technology. A visualization system for use in the interventional MRI has been developed, providing a virtual environment for surgical navigation using real-time images and for controlling the scanner. The visualization system has customized features for certain clinical applications. A training and testing facility has also been established. The introduction of the visualization system in the interventional MRI overcame several ambiguities and inconsistencies that were previously present, and resulted in a more transparent man-machine interface approach. A pilot study using the software to place cryoprobes in an animal liver showed promising results. Augmentation of real-time MR images with 3D rendering and customized navigation features opens new possibilities in intraoperative MRI. The described system can also be extended to other intraoperative imaging modalities.
术中磁共振成像（MRI）作为一种新的成像方式最近已进入手术室。定制可视化系统可能会进一步促进这种成像技术的应用。已经开发出一种用于介入性MRI的可视化系统，它利用实时图像为手术导航并控制扫描仪提供虚拟环境。该可视化系统针对特定临床应用具有定制功能。还建立了一个培训和测试设施。介入性MRI中可视化系统的引入克服了以前存在的一些模糊性和不一致性，并产生了一种更透明的人机界面方法。一项使用该软件在动物肝脏中放置冷冻探针的初步研究显示出了有前景的结果。用三维渲染和定制导航功能增强实时MR图像为术中MRI开辟了新的可能性。所描述的系统还可以扩展到其他术中成像方式。
