Electromagnetic Tracking for Medical Imaging
, 2010 This thesis explores the novel use of a wireless electromagnetic: EM) tracking device in a Computed Tomography: CT) environment. The sources of electromagnetic interference inside a Philips Brilliant Big Bore CT scanner are analyzed. A research version of the Calypso wireless tracking system was set up inside the CT suite, and a set of three Beacon ...

Algorithm for calibration of the electromagnetic tracking system
Proceedings of 2012 IEEE-EMBS International Conference on Biomedical and Health Informatics, 2012Electromagnetic tracking systems (EMTS) are increasingly used in computer assisted surgery systems, motion capture units and military systems. The main application in the medical domain represents the support of minimally invasive surgeries. However, those electromagnetic tracking systems suffer from low accuracy and systematic errors caused by ...

Evaluation of dynamic electromagnetic tracking deviation
SPIE Proceedings, 2009Electromagnetic tracking systems (EMTS's) are widely used in clinical applications. Many reports have evaluated their static behavior and errors caused by metallic objects were examined. Although there exist some publications concerning the dynamic behavior of EMTS's the measurement protocols are either difficult to reproduce with respect of the ...

Stability of miniature electromagnetic tracking systems
Physics in Medicine and Biology, 2005This study aims at a comparative evaluation of two recently introduced electromagnetic tracking systems under reproducible simulated operating-room (OR) conditions: the recently launched Medtronic StealthStation, Treon-EM and the NDI Aurora. We investigate if and to what extent these systems provide improved performance and stability in the presence of

Electromagnetic tracking performance analysis and optimization
2014 36th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2014The purpose of this study is to evaluate the uncertainties of an electromagnetic (EM) tracking system and to improve both the trueness and the precision of the EM tracker.For evaluating errors, we introduce an optical (OP) tracking system and consider its measurement as "ground truth".

Open-Source Tracked Ultrasound with Anser Electromagnetic Tracking
2019Image-guided interventions (IGT) have shown a huge potential to improve medical procedures or even allow for new treatment options. Most ultrasound(US)-based IGT systems use electromagnetic (EM) tracking for localizing US probes and instruments. However, EM tracking is not always reliable in clinical settings because the EM field can be disturbed by ...

Advantages of Optical Compared with Electromagnetic Tracking
Journal of Bone and Joint Surgery, 2009Tracking systems are critical to all types of computer-assisted image-guided intervention. Many technologies exist; however, only optical and electromagnetic systems are widely used commercially. In orthopaedic applications, optical systems dominate because of the large working volume and accuracy, but these systems suffer from deficiencies due to line
