Recent advances in Image-Guided Surgery allows physicians to incorporate up-to-date, high quality patient data in the surgical decision making, and sometimes to directly perform operations based on pre- or intra-operatively acquired patient images. Electromagnetic tracking is the fastest growing area within, where the position and orientation of tiny sensors can be determined with sub-millimeter accuracy in the field created by a generator. One of the major barriers to the wider spread of electromagnetic tracking solutions is their susceptibility to ferromagnetic materials and external electromagnetic sources. The research community has long been engaged with the topic to find engineering solutions to increase measurement reliability and accuracy. This article gives an overview of related experiments, and presents our recommendation towards a robust method to collect representative data about electromagnetic trackers.
图像引导手术的最新进展使医生能够在手术决策中纳入最新的高质量患者数据，有时还能根据术前或术中获取的患者图像直接进行手术。电磁跟踪是其中发展最快的领域，在由发生器产生的场中，可以以亚毫米的精度确定微小传感器的位置和方向。电磁跟踪解决方案更广泛应用的主要障碍之一是它们对铁磁材料和外部电磁源的敏感性。长期以来，研究界一直在研究这个课题，以寻找提高测量可靠性和准确性的工程解决方案。本文概述了相关实验，并提出了我们对于一种稳健方法的建议，该方法用于收集有关电磁跟踪器的代表性数据。
