Algorithm for calibration of the electromagnetic tracking system

Proceedings of 2012 IEEE-EMBS International Conference on Biomedical and Health Informatics, 2012
Electromagnetic 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, 2009
Electromagnetic 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, 2005
This 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 SYSTEM FOR NEUROVASCULAR INTERVENTIONS

Biomedical Engineering, 2010
Electromagnetic tracking systems (EMTS) are widely used in a computer-assisted surgery, motion capture, kinematic studies and military applications. The main application in the medical domain represents minimal invasive surgery. For this purpose, the EMTS systems are integrated into the surgery device, i.e.

High-precision evaluation of electromagnetic tracking

International Journal of Computer Assisted Radiology and Surgery, 2019
Navigation in high-precision minimally invasive surgery (HP-MIS) demands high tracking accuracy in the absence of line of sight (LOS). Currently, no tracking technology can satisfy this requirement. Electromagnetic tracking (EMT) is the best tracking paradigm in the absence of LOS despite limited accuracy and robustness.

Open-Source Tracked Ultrasound with Anser Electromagnetic Tracking

2019
Image-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 ...

Electromagnetic tracking performance analysis and optimization

2014 36th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2014
The 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".

Advantages of Optical Compared with Electromagnetic Tracking

Journal of Bone and Joint Surgery, 2009
Tracking 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

Electromagnetic Tracking for Tomotherapy Systems

International Journal of Radiation Oncology*Biology*Physics, 2012
Conclusions: Our method is a valuable tool that enables us to characterize exosomes and microparticles, and, unlike other available nanoparticle analysis methods, this method permits subset identification and sorting for functional studies of single particles.
