目标跟踪是计算机辅助医疗干预背景下的关键使能技术。允许医疗器械和患者解剖结构的连续定位，这是为表面下解剖结构提供器械引导的先决条件。唯一广泛使用的能够在没有视线限制的情况下实时跟踪小物体的技术是电磁（EM）跟踪。虽然EM跟踪一直是许多研究工作的主题，但临床应用一直缓慢出现。因此，本综述的目的是深入了解EM跟踪用于医疗用途的未来潜力和局限性。我们描述了EM跟踪系统的基本工作原理，列出了误差的主要来源，并总结了已发表的跟踪精度，精度和鲁棒性的研究沿着提出了相应的验证协议。国家的最先进的方法，误差补偿也深入审查。最后，概述了EM跟踪的临床应用。在整篇论文中，我们不仅报告了科学进展，而且还对商业系统进行了审查。鉴于EM跟踪在医学中的适用性的持续辩论，本文提供了一个及时的概述，在该领域的最先进的。
Object tracking is a key enabling technology in the context of computer-assisted medical interventions. Allowing the continuous localization of medical instruments and patient anatomy, it is a prerequisite for providing instrument guidance to subsurface anatomical structures. The only widely used technique that enables real-time tracking of small objects without line-of-sight restrictions is electromagnetic (EM) tracking. While EM tracking has been the subject of many research efforts, clinical applications have been slow to emerge. The aim of this review paper is therefore to provide insight into the future potential and limitations of EM tracking for medical use. We describe the basic working principles of EM tracking systems, list the main sources of error, and summarize the published studies on tracking accuracy, precision and robustness along with the corresponding validation protocols proposed. State-of-the-art approaches to error compensation are also reviewed in depth. Finally, an overview of the clinical applications addressed with EM tracking is given. Throughout the paper, we report not only on scientific progress, but also provide a review on commercial systems. Given the continuous debate on the applicability of EM tracking in medicine, this paper provides a timely overview of the state-of-the-art in the field.
