This study evaluates the new Aurora electromagnetic tracking system, finding substantial accuracy improvements over older models. Performance monitoring over time is also proposed for this 6 degrees of freedom system.

Area of Science:

  • Medical instrumentation
  • Electromagnetic tracking systems

Background:

  • Accurate tracking is crucial for image-guided surgery and interventions.
  • Electromagnetic tracking systems offer advantages but can be susceptible to interference.
  • Evaluating new systems is essential for advancing medical technology.

Purpose of the Study:

  • To assess the accuracy and performance of the newly released 6 degrees of freedom Aurora electromagnetic tracking system.
  • To propose a method for ongoing performance monitoring of the tracking system.
  • To investigate the impact of metallic objects on the system's accuracy.

Main Methods:

  • Utilized a published protocol for system evaluation.
  • Employed a machined base plate to measure positional and orientational errors.

  • Assessed the influence of metallic objects within the system's operating volume.
  • Quantified positional jitter (E(RMS)), relative positional error at various offsets, and rotational errors.

    • Main Results:

    • Positional jitter was measured at 0.17 mm +/- 0.19 mm.
    • Relative positional errors were 0.25 mm +/- 0.22 mm at 50 mm and 0.97 mm +/- 1.01 mm at 300 mm offsets.
    • Mean rotational errors were 0.20 degrees +/- 0.14 degrees (axial) and 0.91 degrees +/- 0.68 degrees (longitudinal).
    • 400-series stainless steel caused the most significant distortion, with a maximum error of 9.4 mm.
    • The new Aurora system shows substantial accuracy improvements compared to previous generations.

    Conclusions:

    • The new Aurora electromagnetic tracking system demonstrates significant improvements in accuracy.
    • The proposed performance monitoring protocol can ensure reliable system operation over time.
    • Understanding and mitigating metallic interference is key for optimal performance in clinical settings.
