脑室外引流的放置是最常进行的神经外科手术之一，因此，是神经外科实习生必须掌握的基本技能。引流管的最佳放置包括在颅骨上选择合适的钻孔，并通过钻孔盲目放置导管穿过侧脑室，以引流脑脊液并缓解颅内压。不理想的轨迹导致多次尝试以击中心室，具有损害脑功能区的潜在风险。在本文中，我们描述了一个模拟环境的开发，以培训居民在尝试放置在活的患者之前获得这些针对性的技能。该平台与我们实验室开发的增强现实图像引导工具相结合，以帮助患者头部脑室的可视化。使用Fitts的方法（Fitts，1954）评估性能，该方法尊重用户权衡速度和准确性的能力。
The placement of an external ventricular drain is one of the most commonly performed neurosurgical procedures, and consequently, is an essential skill to be mastered by neurosurgical trainees. The optimal placement of the drain involves choosing an appropriate burr hole on the skull and blindly placing a catheter through the burr hole to intersect a lateral ventricle in order to drain cerebrospinal fluid and relieve intracranial pressure. Undesirable trajectories lead to multiple tries in order to hit the ventricle, with potential risk of damaging eloquent brain areas. In this paper, we describe the development of a simulation environment to train residents on the acquisition of these targeting skills before attempting the placement on live patients. The platform is coupled with an augmented reality image-guidance tool, developed in our lab, to help with the visualization of the ventricles in the patient's head. Performance is evaluated using Fitts' methodology (Fitts, 1954), which respects the users ability to trade-off speed and accuracy.
