Area of Science:

  • Medical Education
  • Surgical Navigation Technologies
  • Medical Imaging

Background:

  • Teaching image-guided interventions is difficult due to expensive and inaccessible imaging/tracking systems.
  • Hands-on experience is crucial for learning complex medical technologies.
  • Existing training methods lack practical, accessible components for image-guided navigation.

Purpose of the Study:

  • To develop and evaluate a cost-effective software and data infrastructure for hands-on training in image-guided interventions.
  • To address the challenges of high cost and limited accessibility in current training approaches.
  • To enable a wider audience, including students, patients, and clinicians, to understand and use navigation systems.

Main Methods:

  • Developed a software and data infrastructure requiring minimal hardware (LEGO phantom, webcam).
  • Utilized open-source components from the Image-Guided Surgery Toolkit (IGSTK).
  • Evaluated the accuracy of a consumer-grade webcam for use as a tracking system.

Main Results:

  • The developed infrastructure provides a functional, low-cost alternative to expensive systems.
  • Tracking accuracy using a consumer-grade webcam was found sufficient for educational applications.
  • An open-source implementation of basic image-guided navigation components was provided.

Conclusions:

  • The proposed infrastructure effectively overcomes cost and accessibility barriers in image-guided navigation training.
  • Hands-on learning with this system enhances understanding of key technologies.
  • This approach democratizes access to image-guided navigation education and experience.
