This paper summarizes our work over the past several years in developing an image-guided system based on electromagnetic tracking for abdominal interventions. The paper begins with a review of computer-aided surgery and electromagnetic tracking. We next describe our image-guided system along with phantom and animal studies. We then present some technical issues in improving accuracy including pivot calibration, dynamic referencing, and registration using two 5 degree-of- freedom sensors. Electromagnetic tracking has great potential for assisting physicians in precision placement of instruments during minimally invasive interventions. However, the accuracy of these systems needs to be validated in the clinical environment and issues such as respiratory motion and organ deformation need to be addressed.
本文总结了我们在过去几年中开发基于电磁跟踪的腹部介入图像引导系统的工作。本文首先回顾了计算机辅助手术和电磁跟踪。接下来，我们描述了我们的图像引导系统以及模型和动物研究。然后，我们提出了一些提高精度的技术问题，包括枢轴校准、动态参考以及使用两个五自由度传感器进行配准。电磁跟踪在微创介入过程中协助医生精确放置器械方面具有巨大潜力。然而，这些系统的准确性需要在临床环境中得到验证，并且诸如呼吸运动和器官变形等问题需要得到解决。
