'''Welcome to OpenEMT.org!'''
Creating an open source community for electromagnetic tracking systems.

==Discover Anser EMT==
<embedvideo service="youtube" alignment="right" container="frame" valignment="baseline" dimensions="360">https://www.youtube.com/watch?v=44rin3eplZE</embedvideo>
The first open-source electromagnetic tracking system. This paper details the design and specification of an electromagnetic tracking system for research and pre-clinical testing. Experiments were conducted in collaboration with the German Cancer Research Centre ([https://www.dkfz.de DKFZ]) in Heidelberg, Germany.

The Anser system design documentation is available [[System design| here]].
==Tiled Field Generators==
Anser EMT can be configured with multiple field generators to form larger tracking volumes. The design of the field generator can be found [[Field generator] here]. The square nature of the design provides the potentially unlimited tiling configuration for different tracking applications.

==Distortion Detection==
The Anser EMT field generator can be configured to detect the presence of the metal objects in the vicinity of the tracking volume. Metal objects introduce tracking errors in the form of ferromagnetic and Eddy current distortion. The ability to detect and localise the origin of these distortions is the first step in mitigating their error causing effects.

==Lung Navigation==
Electromagnetic tracking is a useful tool in navigating the human airways enabling more effective diagnosis and treatment of lung cancer. We show the first use of Anser EMT in a pre-clinical setting by performing electromagnetic navigation bronchscopy (ENB) on a pig. The open-source medical imaging software [https://www.custusx.org/ CustusX] was used to visualise the EMT position data within the airways. This work was performed in collaboration with the Norwegian Foundation for Industrial and Technical Research [https://www.sintef.no SINTEF].

==Liver Biopsy==
Needle tracking for biopsy is an important application of EMT technology as it enables clincians to precisely navigate the needle's tip to perform biopsy. In this study we apply the Anser EMT system to target liver tumours in a pig and perform targeted ablation therapy.
