Visualization interface for computer assisted surgical training

血管内手术正被广泛应用于许多关键程序，取代了恢复时间长的侵入性医疗手术。然而，在提高临床精确度、手术时间和手术安全性方面，患者和医务人员仍然面临着许多挑战，即不必要的辐射暴露，手术工具的手动导航，缺乏3D可视化，以及缺乏对末端效应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，以在研究环境中使用体模而不是任何人类实验来演示概念验证系统来缓解上述问题。该项目的具体目标是(I)减轻人工导航导管所遇到的困难，(Ii)开发一个原型可视化环境，该环境可用作外科训练模拟器中的一个组件。超声波公司已经开发了一种名为SonixGPS的针导引系统并将其商业化，该系统结合了超声波和电磁跟踪。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.
