The objective of this project is to test and refine a device to assist a surgeon in locating a target of interest as defined from pre-operative medical images. The method, an outgrowth of stereotactic surgery, combines recent advances in medical imaging, high precision position sensing, robotics and computer technology to provide the surgeon with an interactive display of the present position of a surgical instrument on the pre- operative images. Once the device has been calibrated and its accuracy defined and validated, the device can be used to: 1) guide the surgeon directly to the target point, minimizing the size of the total resection, 2) guide the surgeon to objects, such as tumor margins, which may be defined on CT or MR images but be visually indistinguishable from normal tissue, 3) guide the placement of brachytherapy radiation sources for optimum dose distribution, 4) steer laser resection and 5), guide electrode and biosensor placement. If successful, the arm should incorporate the stereotactic advantage of accurate registration of image and physical space without the requirements of present frame-based systems.

该项目的目标是测试和改进设备以协助 外科医生定位术前定义的感兴趣目标 医学图像。该方法是立体定向手术的产物，结合了 医学成像、高精度位置传感的最新进展， 机器人技术和计算机技术为外科医生提供交互式 在预置台上显示手术器械的当前位置 手术图像。一旦设备及其精度被校准 经过定义和验证，该设备可用于：1) 指导外科医生 直接到达目标点，最大限度地减少总切除范围， 2）引导外科医生找到物体，例如肿瘤边缘，这可能是 在 CT 或 MR 图像上定义，但在视觉上与正常图像无法区分 组织，3) 指导近距离放射治疗放射源的放置 最佳剂量分布，4) 引导激光切除和 5)，引导电极 和生物传感器的放置。如果成功的话，手臂应该包含 图像和物理空间精确配准的立体定向优势 无需当前基于框架的系统的要求。
