Visualization interface for computer assisted surgical training

血管内手术正被广泛应用于许多关键手术，取代了恢复时间长的侵入性医疗手术。然而，在提高临床精度、手术时间和患者和医务人员的操作安全性方面仍然存在许多挑战;即，不必要的辐射暴露、手术工具的手动导航、缺乏3D可视化以及缺乏末端执行器的智能规划和自动跟踪。因此，我们的总体目标是开发计算机辅助手术系统的硬件和软件组件，以缓解研究环境中的上述问题，使用幻影而不是任何人类实验来证明概念验证系统。本项目的具体目标是（i）缓解手动导航导管遇到的困难，以及（ii）开发可用作手术培训模拟器组件的原型可视化环境。Ultrasonix已经开发了一种名为SonixGPS（www.ultrasonix.com/GPS）的针引导系统，并将其商业化，该系统结合了超声和电磁跟踪。因此，拟议的项目是他们现有技术的自然延伸。

Endovascular surgery is becoming widely deployed for many critical procedures, replacing invasive medical operations with long recovery times. However, there are still many challenges in improving clinical precision, procedure time, and operation safety to both patients and medical staff; namely, unnecessary exposure to radiation, manual navigation of surgical tools, lack of 3D visualization, and lack of intelligent planning and automatic tracking of the end-effector. Thus, our overall goal is to develop hardware together with software components of a computer assisted surgery system to alleviate the abovementioned problems in a research environment using a phantom instead of any human experiments to demonstrate a proof-of-concept system. The specific objectives in this project are (i) to alleviate the difficulties encountered in manual navigation catheter, and (ii) to develop a prototype visualization environment that can be used as a component in a simulator for surgical training. Ultrasonix has already developed and commercialized a needle guidance system called SonixGPS (www.ultrasonix.com/GPS) combining ultrasound and electromagnetic tracking. The proposed project is thus a natural extension of their existing technology.
