Electromagnetic guided bronchoscopy is a new field of research, essential for the development of advanced investigation of the airways and lung tissue. Consecutive problem-based solutions and refinements are urgent requisites to achieve improvements. For that purpose, our intention is to build a complete research platform for electromagnetic guided bronchoscopy. The experimental interventional electromagnetic field tracking system in conjunction with a C-arm cone beam CT unit is presented in this paper. The animal model and the navigation platform performed well and the aims were achieved; the 3D localization of foreign bodies and their navigated and tracked removal, assessment of tracking accuracy that showed a high level of precision, and assessment of image quality. The platform may prove to be a suitable platform for further research and development and a full-fledged electromagnetic guided bronchoscopy navigation system. The inclusion of the C-arm cone beam CT unit in the experimental setup adds a number of new possibilities for diagnostic procedures and accuracy measurements. Among other future challenges that need to be solved are the interaction between the C-arm and the electromagnetic navigation field, as we demonstrate in this feasibility study.
电磁导航支气管镜检查是一个新的研究领域，对气道和肺组织的高级检查的发展至关重要。连续的基于问题的解决方案和改进是实现进步的迫切要求。为此，我们的目标是构建一个完整的电磁导航支气管镜检查研究平台。本文介绍了结合C形臂锥形束CT单元的实验性介入电磁场跟踪系统。动物模型和导航平台运行良好，目标得以实现；异物的三维定位及其导航和跟踪清除、显示高精度的跟踪准确性评估以及图像质量评估。该平台可能被证明是进一步研发的合适平台以及一个成熟的电磁导航支气管镜检查导航系统。在实验设置中加入C形臂锥形束CT单元为诊断程序和准确性测量增加了许多新的可能性。正如我们在这项可行性研究中所展示的，其他需要解决的未来挑战包括C形臂与电磁导航场之间的相互作用。
