介绍了一种手术引导和可视化系统,它独特地将数据分析和在线介入引导的能力集成到介入MRI的设置中。各种术前扫描(T1和T2加权MRI、MR血管造影和功能性MRI(fMRI))被融合,并自动与介入MR系统的操作场对齐。术前和术中数据都可以被分割以生成关键解剖结构和功能结构的三维表面模型。将模型与由跟踪的手术设备驱动的重新格式化的切片沿着组合在三维场景中。因此,术前数据增强了介入成像,以加快组织表征和精确定位和靶向。随着手术的进行,解剖结构的变化随后降低了术前数据的相关性,介入数据被刷新以用于真正真实的时间的软件导航。该系统已应用于45例神经外科病例,并发现具有有益的规划和指导的效用。J.磁共振影像学2001;13:967-975.

A surgical guidance and visualization system is presented, which uniquely integrates capabilities for data analysis and on-line interventional guidance into the setting of interventional MRI. Various pre-operative scans (T1- and T2-weighted MRI, MR angiography, and functional MRI (fMRI)) are fused and automatically aligned with the operating field of the interventional MR system. Both pre-surgical and intra-operative data may be segmented to generate three-dimensional surface models of key anatomical and functional structures. Models are combined in a three-dimensional scene along with reformatted slices that are driven by a tracked surgical device. Thus, pre-operative data augments interventional imaging to expedite tissue characterization and precise localization and targeting. As the surgery progresses, and anatomical changes subsequently reduce the relevance of preoperative data, interventional data Is refreshed for software navigation in true real time. The system has been applied in 45 neurosurgical cases and found to have beneficial utility for planning and guidance. J. Magn. Reson. Imaging 2001;13:967-975. (C) 2001 Wiley-Liss, Inc.
