Interactive, Image-Guided Surgery (IIGS) is a technique in which the three-dimensional position of any surgical instrument is tracked and that position is displayed on preoperatively obtained tomograms. The research proposed in this project is to extend beyond the initial application of IIGS, intracranial neurosurgery, and to expand the image information provided to the surgeon. The extension of this process will be to spinal surgeries. In order to apply IIGS techniques to spinal applications new forms of registration and display will have to be developed. Inherent in this process will be the development of automatic and semi-automatic segmentation techniques for structures in and about the spine. Intracranial IIGS has led to reduced damage to healthy tissue, smaller incisions, more complete resections and reduced time of surgery. Given the huge number of spinal surgeries relative to intracranial surgeries, if IIGS can provide the same advantages to spinal surgery as it does to intracranial surgeries, the rewards to health care would be enormous. The proposed expansion of the image information includes both vascular and realtime imaging formats. The vascular images will include both conventional projection angiograms and tomographic vascular images such as MRA and CTA. By using realtime imaging techniques such as endoscopy and B- Mode ultrasound in conjunction with tomographic image sets, the advantages of each may be preserved and the drawbacks to each mitigated.

交互式图像引导手术（IIGS）是一种技术， 跟踪任何手术器械的三维位置，并且 位置显示在术前获得的断层图像上。研究 在这个项目中提出的是扩展超出最初的应用程序， IIGS，颅内神经外科，并扩展图像信息 提供给外科医生。 这一过程的延伸将是脊柱手术。为了 将IIGS技术应用于脊柱应用新的配准形式， 显示器将被开发。在这个过程中， 开发自动和半自动分割技术， 脊柱内和周围的结构。颅内IIGS导致了 损伤健康组织，更小的切口，更完整的切除， 缩短手术时间。考虑到脊柱手术的巨大数量 相对于颅内手术，如果IIGS可以提供相同的 脊柱手术和颅内手术一样， 对医疗保健的回报将是巨大的。 所提出的图像信息的扩展包括血管和 实时成像格式。血管图像将包括 传统的投影血管造影和断层血管图像 MRA和CTA。通过使用实时成像技术，如内窥镜和B- 超声模式结合断层图像集的优点 每一个都可以被保存，并且每一个的缺点都被减轻。
